pseudofolliculitis
Last reviewed 03/2021
Pseudofolliculitis describes folliculitis caused by ingrowing hairs in the beard area and on the back of the neck. This condition results in small papules on the areas of skin described (1).
This condition is worse in people with naturally curly hair and Afro-Caribbeans (1).
Scarring commonly occurs associated with this condition (1).
- pseudofolliculitis barbae (also known colloquially as 'ingrown hairs'
or 'razor bumps') is a common chronic inflammatory disorder occurring most
often in regions of thick hair growth after shaving (2)
- pathogenesis involves creating a sharp tip by shaving the distal end
of the hair that enables intrafollicular and transfollicular penetration
of thick hairs into the dermis
- as the hairs grow, they coil back into the dermis, causing an inflammatory
reaction
- characterized clinically by multiple painful, pruritic erythematous papules and, less commonly, pustules, nodules, or abscesses; hyperpigmentation, hypertrophic scars and keloids can also occur

reaction
