Abstract: Introduction: Acquired progressive kinking of the hair (APKH) is a rare condition in which the hair of the scalp changes in appearance. This disorder has been described infrequently over the years, so it is believed that it is being diagnosed late by physicians. We present a case of a patient with APKH. Case: A 13-year-old woman consulted for 8 months of evolution of changes on the appearance of her hair, being darker, thicker, and more brittle than usual. The physical examination reveals the presence of thick short hair and isolated long dark hair in the coronal area. Trichoscopy showed periodic reductions on the diameter of the hair shaft and no areas of alopecia suggestive of APKH. Discussion: APKH is an extremely rare condition in which hair of the scalp changes in appearance. It is very important to know the physical changes produced on the hair to avoid misdiagnosis. We report the case to make this pathology more widely known among professionals and encourage the reporting of this unusual disorder.
