What does your patient need to know at the first visit?  

All patients, regardless of race, gender, or age, are afraid of an alopecia diagnosis. Often, the first thing a patient may say when I enter the examination room is, "Please don't tell me I have alopecia."  

The first step to a successful initial visit for hair loss is addressing the angst around the word alopecia, which helps to manage the patient's hair-induced anxiety. The next priority is setting expectations for the journey including what to expect during the diagnosis process, treatment, and beyond.  

Next is data collection. An extensive hair care practice investigation can begin with a survey that the patient fills out before the visit. Dive into and expand on hair loss history questions, including medical history as well as hair care practices (eg, history of use, frequency, number of years, maintenance for that particular hairstyle) such as braids (eg, individual braids, cornrow braids, with or without added synthetic or human hair), locs (eg, length of locs), chemical relaxers (eg, number of years, frequency, professionally applied or applied at home), hair color, weaves (eg, glued in, sewn in, combination), and more.¹ Include a family history of hair loss, both maternal and paternal.  

The hair loss investigation almost always includes a scalp biopsy, hair-pull test, dermoscopy, photographs, and even blood work, if applicable. Scalp biopsies may reveal more than one type of alopecia diagnosis, which may impact the treatment plan.² Sending the scalp biopsy specimen to a dermatopathologist specializing in alopecia along with clinical information about the patient is preferred. 

What are your go-to treatments?  

My go-to treatments for patients with skin of color (SOC) and hair loss really depend on the specific diagnosis. Randomized, placebo-controlled clinical trials focusing on treatment are lacking in central centrifugal cicatricial alopecia and traction alopecia, which holds true for many other types of alopecia.  

For black patients with central centrifugal cicatricial alopecia, I often address the inflammatory component of the disease with oral doxycycline and either a topical corticosteroid, such as clobetasol, or intralesional triamcinolone. Adding minoxidil-containing products later in the treatment process can be helpful. Various treatment protocols exist but are mainly based on anecdotal evidence.¹ 

For those with traction alopecia, modification of offending hairstyle practices is a must.³ Also, treatment of inflammation is key. Typically, I gravitate to topical or intralesional corticosteroids, followed by minoxidil-containing products. However, a challenge of treating traction alopecia is changing the hair care practices that cause tight pulling, friction, or pressure on the scalp, such as from the band of a tightly fitted wig.  

It is important to discuss potential side effects of any treatment with the patient. For the most common side effects, discuss how to best prevent them. For example, because of the photosensitivity potential of doxycycline, I ask patients to wear sunscreen daily. To prevent nausea, I recommend that they avoid taking doxycycline on an empty stomach, drink plenty of fluids, and avoid laying down within a few hours after taking the medication.  

How do you keep patients compliant with treatment? 

Dermatologists should try to understand their patients' hair. A study of 200 black women demonstrated that 68% of the patients did not think their physician understood their hair,⁴ which likely impacts patients' perceptions of their physician, confidence in the treatment plan, and even compliance with the plan. Attempting to understand the nuances of tightly coiled hair in those of African descent is the first step in the journey of diagnosing and treating hair loss in partnership with the patient.  

Setting the goal is a crucial step toward patient compliance. It may be going out in public without a wig or weave and feeling confident, providing more coverage so affected areas do not show as much, improving scalp tenderness, and/or preventing further progression of the condition. These are all reasonable outcomes and each goal is uniquely tailored to each patient.  

Familiarize yourself with various hair types, hairstyles, and preferred medication vehicles by attending continuing medical education lectures on alopecia in patients with SOC and on nuances to diagnosis and treatment, reading textbooks focusing on SOC, or seeking out mentorship from a dermatologist who is a hair expert in the types of alopecia most commonly affecting patients with SOC.  

What resources do you recommend to patients for more information 

For patients with scarring alopecia, the Cicatricial Alopecia Research Foundation (http://www.carfintl.org/) is a great resource for medical information and support groups. Also, the Skin of Color Society has dermatology patient education information (http://skinofcolorsociety.org/).  

For patients who are extremely distressed by hair loss, I encourage them to see a mental health professional. The mental health impact of alopecia, despite the extent of disease, is likely underestimated. Patients sometimes need our permission to seek help, especially in many SOC communities where even seeking mental health care often is frowned upon.

Postnflammatory hyperpigmentation (PIH) is an acquired hypermelanosis that can occur in children and adults following an inflammatory cutaneous disease or trauma. Postinflammatory hyperpigmentation may last for months to even years. Although PIH may occur in all skin types, it is more common and presents with greater severity and intensity in individuals with skin of color. By the year 2050, 1 in 3 US residents is projected to be Hispanic.¹ It is projected that by 2044, non-Hispanic white individuals (all ages) will make up less than 50% of the US population.² Currently, the majority of the US residents younger than 18 years are minorities. The majority minority population in the United States already exists in those younger than 18 years and is predicted to occur in the adult population by 2044.²

Effective treatment options and management strategies for PIH in adults with skin of color have been described in the literature.³ Due to a paucity of research, the approach to management of PIH in children with skin of color has been based on clinical experience and lessons learned from adult patients. This article focuses on management of PIH in pediatric patients with skin of color, which includes black/African American, African-Caribbean, Hispanic, Asian, Pacific Islander, and American Indian individuals.

Underlying Inflammatory Dermatoses Resulting in PIH

There are numerous conditions that may result in PIH, including but not limited to atopic dermatitis (AD), acne, arthropod bites, and injuries to the skin. Postinflammatory hyperpigmentation may have more of a psychological impact than the inciting disease or injury itself. The most important step in the approach to managing PIH is treating the underlying inflammatory condition that caused the pigmentation.

Parents/guardians may report a chief concern of dark spots, manchas (stains), blemishes, or stains on the skin, often with no mention of a coexisting inflammatory dermatosis. Parents/guardians of children with skin of color often have personally experienced PIH and may be determined to shield their children from similar angst associated with the condition. Although physicians may see just another pediatric patient with PIH, the child’s parents/guardians may see a condition that will be readily perceptible during major life events, such as the child’s prom or even his/her wedding day. Promptly diagnosing and instituting early treatment of inflammatory conditions associated with PIH may accelerate resolution and prevent worsening of the pigmentation.³

Select inflammatory dermatoses that are common in children with skin of color and may lead to PIH are highlighted below. Although this list is not comprehensive, the approach and management strategies should prompt creation of plans that keep PIH in mind when treating primary inflammatory skin diseases.

Atopic Dermatitis
Atopic dermatitis may induce PIH or hypopigmentation of the skin in children with skin of color. Developing a plan for AD flare prevention, as well as management of mild, moderate, and severe AD flares, is imperative in pediatric patients. Prevention plans should include gentle skin care, twice-daily application of emollients to the full body, and reduction of Staphylococcus aureus loads on the skin. The treatment action plan for mild to moderate flares may include topical corticosteroids, immunomodulators, and nonsteroidal agents. Treatment options for severe AD or patients who were unsuccessfully treated with other therapies may include phototherapy, biologics, and methotrexate, among others.⁴ Creating action plans for AD flares is a vital step in the prevention of PIH in patients with skin of color. Additionally, PIH should not be considered a sign of AD treatment failure.

Acne
Acne is a common skin disorder seen in patients with skin of color.⁵ A prospective observational study found that 34.3% of 683 children aged 9 to 14 years in a pediatric ambulatory clinic had acne.⁶ The number of preadolescents with acne is growing. Most cases are not associated with underlying endocrinopathy.⁷ With the growing population of children with skin of color in the United States along with the increasing childhood acne rate and subsequent inherent risk for hyperpigmentation, early acne interventions should be considered in pediatric acne patients with skin of color to reduce the impact of PIH in those at risk.

In a survey study of 313 adult acne patients with skin of color, 37.2% reported the presence of dark marks lasting 4 months or longer.⁵ Regardless of the severity of the acne, treatment should be initiated as tolerated in those with PIH. Adolescent acne patients with skin of color may develop PIH that is more severe and longer lasting than the acne itself.

The foundation for treatment of acne in adolescent skin of color patients is the same as those without skin of color, including topical retinoids, topical antibiotics, oral antibiotics, and isotretinoin when needed. Topical tretinoin, adapalene, azelaic acid, and tazarotene not only treat acne but also are a valuable part of the treatment armamentarium for PIH. Several studies in adults with skin of color have demonstrated improvement of PIH from the use of topical retinoids alone.^8-10 Despite wanting to treat the acne aggressively, special guidance should be given to prevent retinoid dermatitis, which may lead to PIH.¹⁰ Demonstrating the application of the topical acne medications, discussing how to avoid potential side effects, and giving permission to skip applications, if needed, may empower families to make adjustments between visits to limit irritation that might prompt further PIH. Incorporating α-hydroxy acid–based cleansers, α-hydroxy acid–based chemical peels, or salicylic acid chemical peels may be warranted in the setting of intense PIH. Selecting treatments that not only help the inflammatory disease leading to the PIH but also can help improve the pigmentation are preferred; however, the risks and benefits have to be weighed because many treatments that work well for PIH also may cause irritation, leading to new or worsening PIH.

Arthropod Bites
Arthropod bites cause inflamed pruritic papules and nodules, and the resulting PIH in those with darker skin types may be quite dramatic. Parents/guardians should be instructed to have a low-potency topical corticosteroid on hand to use on bites for a few days when they appear, which will not only help with the inflammation associated with the bite but also will help decrease pruritus and subsequently skin injury from scratching. In homes with pets, checking animals routinely for fleas and other infestations is helpful. In the setting of repeated arthropod bites in the spring and summer, applying bug repellant with 10% to 30% DEET (N,N-diethyl-meta-toluamide) on the child’s clothing and exposed body areas before playing outside or in the morning before school or camp may prevent some bites. There are DEET alternatives, such as picaridin, that may be used. Product instructions should be followed when using insect repellants in the pediatric population.¹¹

PIH Management Strategies

Gentle Skin Care Routine
There are misconceptions that areas of hyperpigmentation on the skin are caused by dirt and that scrubbing the skin harder may help to lighten the affected areas. Parents/guardians may report that the child’s skin looks dirty or, in the setting of acne, view dirt as the cause of the skin condition, which may prompt the patient to scrub the skin and the friction further worsens the PIH. Use of daily gentle cleansers and moisturizers is advised to keep the skin moisturized and free of further potential irritation and dryness that may prompt scratching or flares of the underlying condition.

Photoprotection
During the treatment course for PIH, using sun protection is helpful to prevent further darkening of the PIH areas. Sun protection may be in the form of broad-spectrum sunscreen, hats, or sun-protective clothing. Patients should be encouraged to apply sunscreen daily and to reapply every 2 hours and after water-based activities.¹² For pediatric and adolescent populations, practicing sun-protective behaviors before school or outdoor activities also should be advised, as many families only think about sun protection in the setting of sunny vacation activities. Research has demonstrated that individuals with skin of color may not realize that they can be affected by skin cancer,¹³ thus they may not have any experience selecting, applying, or regularly using sunscreens. Products that do not leave a white hue on the skin are suggested for adolescents who may be sensitive about their appearance following sunscreen application.

Skin Lightening Treatments

Although the most important therapy for PIH is to treat the underlying inflammatory conditions, some parents/guardians may desire additional options due to the extent of involvement of the PIH, its psychological impact on the child, or adverse effect on the child’s quality of life.¹⁴ In adolescents, incorporating an α-hydroxy acid–based cleanser, glycolic acid chemical peels, salicylic acid chemical peels, and topical cosmeceuticals may be warranted in the setting of intense PIH and acne. However, irritation may lead to further dyspigmentation.

Topical ammonium lactate 12% is lactic acid neutralized with ammonium hydroxide that is formulated as a lotion or a cream. It is used to hydrate dry skin and may decrease corneocyte cohesion.¹⁵ Topical ammonium lactate also has been used anecdotally for PIH on the body during periods of watchful waiting.

Topical hydroquinone, the gold standard for treating hyperpigmentation,^3,16 is not approved in children, but some parents/guardians elect to utilize hydroquinone off label to accelerate the clearing of distressing PIH in adolescents. Careful consideration including a discussion of potential risks and alternatives (eg, watchful waiting) should be highlighted.

In the setting of chronic inflammatory conditions that recur and remit, potentially irritating topical treatments should be used only during periods when symptoms of inflammation such as itching or erythema are absent.

Conclusion

Despite the best management efforts, PIH in some patients with skin of color may be present for months to years. In the pediatric skin of color population, treatment of the underlying inflammatory condition, gentle skin care, use of photoprotection, and time may be all that is needed for PIH resolution. With their parent/guardians’ consent, adolescents distressed by PIH may decide to pursue more aggressive, potentially irritating treatments. Above all, the most important management in the setting of PIH is to treat the underlying inflammatory condition causing the PIH and set reasonable expectations. For challenging cases, pediatric dermatologists with special expertise in treating pediatric and adolescent patients with skin of color may be consulted.

There are numerous conditions that may result in PIH, including but not limited to atopic dermatitis (AD), acne, arthropod bites, and injuries to the skin. Postinflammatory hyperpigmentation may have more of a psychological impact than the inciting disease or injury itself. The most important step in the approach to managing PIH is treating the underlying inflammatory condition that caused the pigmentation.

Parents/guardians may report a chief concern of dark spots, manchas (stains), blemishes, or stains on the skin, often with no mention of a coexisting inflammatory dermatosis. Parents/guardians of children with skin of color often have personally experienced PIH and may be determined to shield their children from similar angst associated with the condition. Although physicians may see just another pediatric patient with PIH, the child’s parents/guardians may see a condition that will be readily perceptible during major life events, such as the child’s prom or even his/her wedding day. Promptly diagnosing and instituting early treatment of inflammatory conditions associated with PIH may accelerate resolution and prevent worsening of the pigmentation.³

Select inflammatory dermatoses that are common in children with skin of color and may lead to PIH are highlighted below. Although this list is not comprehensive, the approach and management strategies should prompt creation of plans that keep PIH in mind when treating primary inflammatory skin diseases.

Atopic Dermatitis
Atopic dermatitis may induce PIH or hypopigmentation of the skin in children with skin of color. Developing a plan for AD flare prevention, as well as management of mild, moderate, and severe AD flares, is imperative in pediatric patients. Prevention plans should include gentle skin care, twice-daily application of emollients to the full body, and reduction of Staphylococcus aureus loads on the skin. The treatment action plan for mild to moderate flares may include topical corticosteroids, immunomodulators, and nonsteroidal agents. Treatment options for severe AD or patients who were unsuccessfully treated with other therapies may include phototherapy, biologics, and methotrexate, among others.⁴ Creating action plans for AD flares is a vital step in the prevention of PIH in patients with skin of color. Additionally, PIH should not be considered a sign of AD treatment failure.

Acne
Acne is a common skin disorder seen in patients with skin of color.⁵ A prospective observational study found that 34.3% of 683 children aged 9 to 14 years in a pediatric ambulatory clinic had acne.⁶ The number of preadolescents with acne is growing. Most cases are not associated with underlying endocrinopathy.⁷ With the growing population of children with skin of color in the United States along with the increasing childhood acne rate and subsequent inherent risk for hyperpigmentation, early acne interventions should be considered in pediatric acne patients with skin of color to reduce the impact of PIH in those at risk.

In a survey study of 313 adult acne patients with skin of color, 37.2% reported the presence of dark marks lasting 4 months or longer.⁵ Regardless of the severity of the acne, treatment should be initiated as tolerated in those with PIH. Adolescent acne patients with skin of color may develop PIH that is more severe and longer lasting than the acne itself.

The foundation for treatment of acne in adolescent skin of color patients is the same as those without skin of color, including topical retinoids, topical antibiotics, oral antibiotics, and isotretinoin when needed. Topical tretinoin, adapalene, azelaic acid, and tazarotene not only treat acne but also are a valuable part of the treatment armamentarium for PIH. Several studies in adults with skin of color have demonstrated improvement of PIH from the use of topical retinoids alone.^8-10 Despite wanting to treat the acne aggressively, special guidance should be given to prevent retinoid dermatitis, which may lead to PIH.¹⁰ Demonstrating the application of the topical acne medications, discussing how to avoid potential side effects, and giving permission to skip applications, if needed, may empower families to make adjustments between visits to limit irritation that might prompt further PIH. Incorporating α-hydroxy acid–based cleansers, α-hydroxy acid–based chemical peels, or salicylic acid chemical peels may be warranted in the setting of intense PIH. Selecting treatments that not only help the inflammatory disease leading to the PIH but also can help improve the pigmentation are preferred; however, the risks and benefits have to be weighed because many treatments that work well for PIH also may cause irritation, leading to new or worsening PIH.

Arthropod Bites
Arthropod bites cause inflamed pruritic papules and nodules, and the resulting PIH in those with darker skin types may be quite dramatic. Parents/guardians should be instructed to have a low-potency topical corticosteroid on hand to use on bites for a few days when they appear, which will not only help with the inflammation associated with the bite but also will help decrease pruritus and subsequently skin injury from scratching. In homes with pets, checking animals routinely for fleas and other infestations is helpful. In the setting of repeated arthropod bites in the spring and summer, applying bug repellant with 10% to 30% DEET (N,N-diethyl-meta-toluamide) on the child’s clothing and exposed body areas before playing outside or in the morning before school or camp may prevent some bites. There are DEET alternatives, such as picaridin, that may be used. Product instructions should be followed when using insect repellants in the pediatric population.¹¹

PIH Management Strategies

Gentle Skin Care Routine
There are misconceptions that areas of hyperpigmentation on the skin are caused by dirt and that scrubbing the skin harder may help to lighten the affected areas. Parents/guardians may report that the child’s skin looks dirty or, in the setting of acne, view dirt as the cause of the skin condition, which may prompt the patient to scrub the skin and the friction further worsens the PIH. Use of daily gentle cleansers and moisturizers is advised to keep the skin moisturized and free of further potential irritation and dryness that may prompt scratching or flares of the underlying condition.

Photoprotection
During the treatment course for PIH, using sun protection is helpful to prevent further darkening of the PIH areas. Sun protection may be in the form of broad-spectrum sunscreen, hats, or sun-protective clothing. Patients should be encouraged to apply sunscreen daily and to reapply every 2 hours and after water-based activities.¹² For pediatric and adolescent populations, practicing sun-protective behaviors before school or outdoor activities also should be advised, as many families only think about sun protection in the setting of sunny vacation activities. Research has demonstrated that individuals with skin of color may not realize that they can be affected by skin cancer,¹³ thus they may not have any experience selecting, applying, or regularly using sunscreens. Products that do not leave a white hue on the skin are suggested for adolescents who may be sensitive about their appearance following sunscreen application.

Skin Lightening Treatments

Although the most important therapy for PIH is to treat the underlying inflammatory conditions, some parents/guardians may desire additional options due to the extent of involvement of the PIH, its psychological impact on the child, or adverse effect on the child’s quality of life.¹⁴ In adolescents, incorporating an α-hydroxy acid–based cleanser, glycolic acid chemical peels, salicylic acid chemical peels, and topical cosmeceuticals may be warranted in the setting of intense PIH and acne. However, irritation may lead to further dyspigmentation.

Topical ammonium lactate 12% is lactic acid neutralized with ammonium hydroxide that is formulated as a lotion or a cream. It is used to hydrate dry skin and may decrease corneocyte cohesion.¹⁵ Topical ammonium lactate also has been used anecdotally for PIH on the body during periods of watchful waiting.

Topical hydroquinone, the gold standard for treating hyperpigmentation,^3,16 is not approved in children, but some parents/guardians elect to utilize hydroquinone off label to accelerate the clearing of distressing PIH in adolescents. Careful consideration including a discussion of potential risks and alternatives (eg, watchful waiting) should be highlighted.

In the setting of chronic inflammatory conditions that recur and remit, potentially irritating topical treatments should be used only during periods when symptoms of inflammation such as itching or erythema are absent.

Conclusion

Despite the best management efforts, PIH in some patients with skin of color may be present for months to years. In the pediatric skin of color population, treatment of the underlying inflammatory condition, gentle skin care, use of photoprotection, and time may be all that is needed for PIH resolution. With their parent/guardians’ consent, adolescents distressed by PIH may decide to pursue more aggressive, potentially irritating treatments. Above all, the most important management in the setting of PIH is to treat the underlying inflammatory condition causing the PIH and set reasonable expectations. For challenging cases, pediatric dermatologists with special expertise in treating pediatric and adolescent patients with skin of color may be consulted.
