Question

How it's possible that dht helps in growing beard but not hair on head?

Answer 1

The hair on the head grows without the presence of DHT, but armpit hair, pubic hair, and beard hair cannot growwithout androgens. ... For reasons thatare not well understood, DHT is essential for most hair growth, but it is detrimental to head hair growth. DHTis thought to attach to androgen receptors on hair follicles.
