Acne keloidalis nuchae: keloid-like bumps on the neck
A specific, often-missed condition at the back of the scalp and neck.

A distinct keloid-related condition deserves its own attention: acne keloidalis nuchae, which produces firm, keloid-like bumps at the back of the scalp and neck, most often in men with coarse or curly hair.
It begins as inflamed bumps along the hairline that, over time, can merge into raised keloid-like plaques and cause permanent hair loss in the area. Friction from close haircuts, collars, and helmets, along with the hair type, contributes. Because it is frequently mistaken for ordinary razor bumps or simple acne, it is often left to progress.
Early treatment matters and works far better than late intervention: topical and injected anti-inflammatories, avoiding close shaving and friction at the hairline, and addressing it before extensive plaques and scarring form. Advanced cases may need procedural treatment. The key message is recognition, persistent firm bumps at the back of the neck and scalp are not just razor bumps to ignore but a treatable condition that worsens if neglected. A dermatologist can confirm it and intervene while it is still manageable.
