Hair Stopped Falling out

I've had thinning hair, finer hair and more hair loss everywhere, since I was 65. It reached critical at 76. 3 exosome treatments, 8 weeks apart, with injected exosomes (Many hallow injections were easy to tolerate) in scalp stopped hair loss after 2nd treatment and allowed some growth. This has continued until December 2024. Now I'm loosing a few hairs a day. I know we normally loose 100 a day, so this is still good. I can style hair the way I want and how I used to, so it's was worth it. The treatments are $500 a vile and you need 3 to cover whole head. It's too expensive to continue every 8 weeks, but, starting 6 weeks ago, I'm trying topical 5% green tea extract and mint extract applied daily, hoping to prolong results. I section hair and spray scalp, rubbing it around on scalp. These 2 topicals have scientifically proven results for stopping the type of general hair loss from age that I have. I've noticed that I don't get the back of the head sink when I sweat or don't wash hair for a few days. There must be some anti-microbial properties to the combination. There is also a study that shows that taking, orally, a combination of persimmon leaf extract and green tea extract (2/1 ratio) increases size of hair (returns to near normal) and lessens hair loss after 3 months of use. Of course you must continue it as long as you want results. There is no product you can purchase as of this writing, and the summary of the study did not say how much to take. So I'm just experimenting. Be careful with green tea, as it inhibits iron absorption. I leave 4 -6 hours between taking this blend and eating iron-rich food. It's too early to know if topicals will do what exosomes did, but if it works, it will save my hair and a lot of money.
