Acquired Progressive Kinking of the Hair

“…1999;135:1223-1226 A CQUIRED progressive kinking of the hair (APKH) was first described by Wise and Sulzberger 1 in 1932. Since then fewer than 20 cases have been reported in the literature, [2][3][4][5][6][7][8][9][10][11][12][13][14] mainly as single case reports. The possibility that APKH could represent a clinical variety of androgenetic alopecia was first postulated by Mortimer and coauthors 3 in 1985 and recently supported in the article by Boudou and Reygagne,4 who showed pathological features consistent with the diagnosis of androgenetic alopecia as well as increased scalp concentrations of dihydrotestosterone in a patient affected by this condition.…”

“…This variety has been reported in 3 patients, including 2 females. [12][13][14] In all patients, the condition remained stable in the follow-up period, affected non-androgen-dependent follicles, and was not associated with hair thinning. This variety of APKH may clinically resemble woolly hair nevus, but it is acquired and not congenital.…”
