Lichen planopilaris is a rare, chronic condition causing hair loss, mainly in middle-aged women, and early treatment is important to prevent permanent baldness.

This article discusses a case of patchy alopecia areata that spares greying hairs but reports no new findings; it refers to existing literature for context.

This study found that eccrine duct dilation is significantly more frequent in cicatricial alopecias compared to noncicatricial alopecias, possibly due to the scarring process.

In this study, three patients with alopecia areata exhibited spotty absence of the whiteness of their nail lunulae, potentially due to defects in the matrical epithelium.

Hair follicle-derived melanocyte transplant could effectively treat vitiligo by restoring skin color.

This case report describes a 52-year-old black woman with diffuse scalp swelling and thinning hair attributed to a large increase in the thickness of scalp subcutaneous fatty tissue.

This study suggests that pseudopelade may be an autonomous disease based on its distinctive clinical and histopathological features not present in other scarring alopecias.

This case study describes a Doberman Pinscher with a unique alopecic variant of chronic cutaneous lupus erythematosus that progressed to systemic lupus erythematosus, highlighting a rare autoimmune alopecia form in dogs.

This narrative review reports that scalp micropigmentation offers immediate cosmetic improvements in hair density appearance, but does not promote actual hair regrowth and results vary based on the operator's skill.
