Pseudofolliculitis Barbae:
It is easier to appreciate the post-inflammatory hyperpigmentation of pseudofolliculitis barbae in darker skin tones. Though notice the pink papules with perifollicular erythema in lighter skin tones. Even if erythema is not appreciated, the presence of papules should be interpreted as active disease. Furthermore, you can see here how the coiled hair is seen re-entering the dermis creating an inflammatory response.

Rosacea:
Erythematous, violaceous, or hyperpigmented patches may present with telangiectasias on the cheeks and glabella. In darker skin tones acneiform papules amidst mild phymatous changes (pronounced and dilated ostia) may be a better diagnostic clue. It is important not to be limited by the guideline based essential feature of persistent erythema.
One of the early signs of rosacea is flushing, which can be easily missed or even mistaken in darker skin tones for another condition. However, often all patients describe a feeling of warmth.

Alopecia Areata:
Though this collection of images depicts the scalp, the patchy or coin-shaped hair loss of alopecia areata can develop on other locations of the body including the beard, eyebrows, eyelashes, axillary, and could even include the inside of the ears and nose. Notice the fine white hair that will thicken and regain color with time— a sign of regrowth.
Note the exclamation mark hairs that are characteristic of alopecia areata. Keep in mind to examine the patient’s nails—they might be brittle and have dents or ridges. Furthermore, alopecia areata presenting on the frontotemporal scalp in coarser hair types can often be misdiagnosed as traction alopecia. Therefore it is important to take a good history combined with a thorough clinical examination (and/or biopsy, if necessary) to rule out different forms of alopecia.

Here we can appreciate the erythema of inflammatory papules in lighter skin tones and the brown coloration of inflammatory papules mimicking post-inflammatory hyperpigmentation in darker skin tones.

Rosacea:
Erythematous, violaceous, or hyperpigmented patches may present with telangiectasias on the cheeks and glabella. In darker skin tones acneiform papules amidst mild phymatous changes (pronounced and dilated ostia) may be a better diagnostic clue. It is important not to be limited by the guideline based essential feature of persistent erythema.
One of the early signs of rosacea is flushing, which can be easily missed or even mistaken in darker skin tones for another condition. However, often all patients describe a feeling of warmth.

Folliculitis:
Note the follicular pustules present in all of the images. However, if the location of the pustules are on the posterior scalp or beard area, these might represent early presentation of other follicular conditions such as acne keloidalis nuchae or pseudofolliculitis barbae respectively. Post-inflammatory sequelae will also be more prominent in darker skin tones—an impact that is often disabling to the patient but also a clinical sign of chronicity.

Pseudofolliculitis Barbae:
It is easier to appreciate the post-inflammatory hyperpigmentation of pseudofolliculitis barbae in darker skin tones. Though notice the pink papules with perifollicular erythema in lighter skin tones. Even if erythema is not appreciated, the presence of papules should be interpreted as active disease. Furthermore, you can see here how the coiled hair is seen re-entering the dermis creating an inflammatory response.

Hidradenitis Suppurativa:
Hidradenitis suppurativa is a fluctuant and polymorphic disease affecting mainly intertriginous areas. In darker skin tones, the papulonodules may initially present with a violaceous or brown hue instead of the more classic presentation of erythematous papules or nodules. Moreover, post-inflammatory hyperpigmentation is often more noticeable throughout the course of the disease.

Alopecia Areata:
Though this collection of images depicts the scalp, the patchy or coin-shaped hair loss of alopecia areata can develop on other locations of the body including the beard, eyebrows, eyelashes, axillary, and could even include the inside of the ears and nose. Notice the fine white hair that will thicken and regain color with time— a sign of regrowth.
Note the exclamation mark hairs that are characteristic of alopecia areata. Keep in mind to examine the patient’s nails—they might be brittle and have dents or ridges. Furthermore, alopecia areata presenting on the frontotemporal scalp in coarser hair types can often be misdiagnosed as traction alopecia. Therefore it is important to take a good history combined with a thorough clinical examination (and/or biopsy, if necessary) to rule out different forms of alopecia.

Alopecia Areata:
Though this collection of images depicts the scalp, the patchy or coin-shaped hair loss of alopecia areata can develop on other locations of the body including the beard, eyebrows, eyelashes, axillary, and could even include the inside of the ears and nose. Notice the fine white hair that will thicken and regain color with time— a sign of regrowth.
Note the exclamation mark hairs that are characteristic of alopecia areata. Keep in mind to examine the patient’s nails—they might be brittle and have dents or ridges. Furthermore, alopecia areata presenting on the frontotemporal scalp in coarser hair types can often be misdiagnosed as traction alopecia. Therefore it is important to take a good history combined with a thorough clinical examination (and/or biopsy, if necessary) to rule out different forms of alopecia.

Central Centrifugal Cicatricial Alopecia:
Central centrifugal alopecia (CCCA) can present at various stages with unique characteristics ranging from hair breakage and thinning, to significant follicular dropout and scarring. During flares, a “spongy” like edema can be noted upon palpation. The presence of a peripilar white halo is a dermatoscopic feature that suggests the diagnosis of CCCA.
Patients with CCCA often present with tiny bumps and a shiny appearance of the scalp, which can be seen here.

Lichen Planopilaris + Frontal Fibrosing Alopecia:
Earlier in disease course, the perifollicular erythema of lichen planopilaris (LPP) may appear gray or violaceous in darker skin tones. As LPP progresses, it can present as progressive patchy scarring alopecia on the frontal and parietal scalp, distinguishing it from the centrifugal spread of scarring alopecia on the vertex scalp seen in CCCA.
Frontal fibrosing alopecia (FFA) in darker skin tones with more tightly coiled hair can be distinguished from advanced traction alopecia by eyebrow loss and grayish to brown hyperpigmentation of the forehead.
