Talk to General Physician on Androgenic Alopecia

I am facing severe hairloss since the age of 14. Got diagnosed with androgenic alopecia in 2019 and dr prescribed me minoxidil and anagain for 3 months. But I couldn't notice any difference then I had 4 prp sessions and still my hairfall is increasing. Its been 8 months since I had my last prp session. My hair are very brittle, thin and I lose so many hair strands just by a slight touch. Now many bald spots are noticeable. Any solution left other than hair transplant?
