Severe hair loss. As reduce hair fall?

I have been facing this problem of hair fall from past 4 years.Since childhood I had thin hair (density wise as well as the hair type) but as I turned 18 it started getting worse. I have extremely thin hair on the top of my head and a lot of scalp is visible especially in the crown area.Initially I was taking homeopathy treatment but after 2 years into the treatment I didn't find it as effective as the initial 2 years.I have recently stopped the homeopathy treatment and thinking about the prp treatment.Would it help ? I also take iron supplements (Autrin - 1 a day) as it was advised by the doctor, have been taking this for a long time now . As soon as I stop taking iron supplements the hair loss gets worse. Initially I was told its CTE but I think it has progressed to female pattern baldness. Is there any treatment that would help me improve the quality of my hair as well as reduce hair fall ? Any suggestions on where to get prp treatment in Hyderabad. Thanks.
