Thanks for the query. The cause of hair fall needs to be established before proceeding for a hair fall therapy and it is easily done by a clinical examination alone most of the times. The treatment typically consists of usage of oral medication (Finasteride) and topical lotion (Minoxidil in 5% strength). One needs to be patient with the treatment protocol as it takes months to see initial improvement. Minoxidil is recommended by US-FDA for indefinite usage. Certain dermatologists supplement biotin, hair serum and advice procedures like PRP therapy which may accelerate the rate of hair growth. PRP needs multiple sessions (4-6) roughly at 6 weeks intervals. PRP therapy is increasingly being accepted by dermatologists all over the world.
