Hi,
It seems like your
hair fall might be due to
male pattern baldness or androgenetic alopecia. It is basically a hormonal as well as genetic condition. You do not need to go for DHT test. At earlier stage, it can be treated with topical therapy like
minoxidil and oral drug finesteride. However as the baldness progresses, these therapies might not work. In advanced cases of baldness, mesotherapy with PRP, minoxidil, stem cells can be tried. In mesotherapy, drugs are directly instilled in hair follicle through micro needles. If nothing works, surgical
hair transplantation is the best choice. So basically to understand what will work best for you,an appointment with
dermatologist needs to be fixed. Take care.
