Corkscrew hairs, also known medically as pili torti, are a specific type of hair shaft abnormality where the hair is twisted along its length. This condition is often linked to deficiencies in certain vitamins crucial for protein structure and maintenance.
Vitamin C, also known as ascorbic acid, plays a vital role in the synthesis of collagen. Collagen is a key structural protein found in skin, hair follicles, and blood vessels.
The characteristic corkscrew appearance of hairs is a known clinical sign associated with a significant lack of Vitamin C.
Therefore, corkscrew hairs are seen due to deficiency of Vitamin C.
