@girl_HL A topical dht remover is Nizoral 2% shampoo. The only one I know of. It's a weak one, but it helps alot. I use a nozzle to ONLY APPLY TO MY SCALP (and put conditioner on my hair itself) to prevent the harshness on my hair that nizoral can cause.
Internally, I'm using Spironolactone (a low dose, it's harsh also, increases estrogen which causes some breast cancers so if you use, I suggest supplementing with wheat bran which decreases estrogen. I do about 7 tsp's in water a day. And I try to eat at least 1 cruciferous veggie to help against any breast cancers).
Internally I'm also going to do Saw Palmetto EXTRACT. The extract is proven to work for some. It helps me better than the...dry leaf.... Taking 320mg once or twice a day should help.
Also, what works for me like medicine is an anti inflammatory diet. Low to no sugar, pasta's, and heavily decreased carbs. The more vegetables and lean meats I eat, the less hair I shed.
