FAQ
Frequently Asked Questions
Not exactly. While both involve lack of hair, 'baldness' often implies hair loss after growth. 'Atrichia' is a more precise medical term often indicating a congenital, complete absence of hair and follicles.
As a fundamental absence of hair follicles, congenital atrichia currently has no cure to regrow hair. Management focuses on the skin's health and, if desired, the use of wigs or hairpieces.
Alopecia is a broader term for hair loss from any cause, where hair follicles may still be present but inactive. Atrichia specifically refers to a state where hair follicles are missing or completely non-functional from the start.
No, it is a highly specialized term used almost exclusively by healthcare professionals (dermatologists, geneticists) and researchers. The average person will never encounter or need to use this word.
