>>18217203rosemary or peppermint oil with some very slight microneedling (just to make it absorb better) is pretty good for topical DHT reduction
do it sparingly on the worst spots and then the night before you wash your hair you can do it a little larger scale, because the issue when you put on alot it will look greasy.
Rosemary smells fantastic though and it won`t hurt your dick as much as internal DHT blockers might.
I also take some saw palmetto, Biotin, Copper, Kieselguhr (silicia supplement) helps for thickness, B Vitamins
and make sure your thyroid is working normally, low thyroid can also thin hair
combined the things work quite well i barely lose hair now
