I wish to thank Dr Brauner for his constructive criticism regarding the article "Pseudofolliculitis Capitis" by Dr Smith and me (Archives 113:328-329, 1977). I continue to support the concept that pseudofolliculitis barbae is a condition that occurs in certain people who inherit the characteristic of having curved hair follicles that produce curly and kinky hairs. The disease is quite common in black men with curly hair, who shave their faces and necks. In persons with straight hair, pili incarnati is indeed uncommon.
With regard to dermatitis papillaris capillitii, the terms sycosis nuchae, folliculitis cheloidalis, and acne keloid are used interchangeably by various authors. One reference states that the nape of the neck and occipital region of the scalp of black men are the sites of this chronic form of keloid acne. It further states that the patient often has a seborrheic constitution with acne vulgaris or hidradenitis suppurativa.1 An
