Symptoms and Causes
This form of hair loss occurs almost exclusively in men of African descent, but can occasionally occur in women. It begins as small firm bumps in the back of the neck Latin nuchae) or elsewhere, which over time can become larger and more confluent. In severe cases it can result in a large keloid-appearing plaque. Mechanical trauma from haircuts or clippers may play a role in initiating this condition, however it is still considered a primary scarring alopecia, often co-existent with CCCA (central centrifugal cicatricial alopecia).
Diagnosis & Treatments
It is best to start treatment when this is at the early stages. This condition may improve with topical corticosteroids, intralesional steroids and anti-inflammatory antibiotics such as doxycycline or minocycline. Laser hair removal may occasionally help. Severe cases resulting in keloid-like plaques may warrant surgical excision.
