    TLDR APKH in young males may signal early hair loss and needs early attention.
    The review article discusses acquired progressive kinking of the hair (APKH), a condition characterized by changes in hair texture such as increased curliness and frizziness, particularly in young males. The focus is on the androgen-dependent phenotype of APKH, which may be an early sign of androgenetic alopecia. The authors integrate clinical, trichoscopic, and histopathological findings and propose a framework to differentiate between androgen-dependent and non–androgen-dependent subtypes. The review highlights patterns of progression, diagnostic clues, and therapeutic implications, emphasizing the importance of recognizing this condition for timely intervention.
