DPA (Diffuse Patterned Alopecia)

DPA (Diffuse Patterned Alopecia) refers to hair loss that shows widespread thinning across the scalp while retaining a patterned distribution of follicular miniaturization rather than completely uniform shedding. People with DPA typically notice overall reduced hair density, increased scalp visibility, and a mixture of finer, shorter hairs alongside thicker terminal hairs; hormonal, genetic, and age-related factors often influence its development.

Diagnosis relies on clinical history and scalp examination and may be aided by trichoscopy, hair-pull testing, laboratory screening for systemic contributors, and occasionally scalp biopsy to confirm miniaturization. Management is individualized and can include treating underlying causes, medical therapies such as topical minoxidil or anti-androgen agents when appropriate, and consideration of hair restoration procedures for stable, suitable cases, with regular follow-up to monitor progression and response.
