I am doing the following to try to maximize my "natural assets" (i.e. get as much regrowth as possible before considering transplants):
1. Rogaine. I'm on my second bottle. It costs about $45 a bottle, which lasts about 20 days.
2. Nizoral shampoo Monday, Wednesday and Friday. Apparently, Nizoral helps block or destroy DHT on the scalp, and assists the Rogaine, amplifying its effects.
3. NutriCap. Two capsules a day. Touted as a hair-thickening/regrowth suppliment.
4. Saw Palmetto capsules. Two a day, as often as I can remember, what with all the other regimens I now have.
I added the Saw Palmetto capsules when I read about MinSaw, which was a combination of Minoxidil and Saw Palmetto, with retinolic acid. I looked for it, but it's apparently either very hard to find or unavailable at present.
I will say that having done the above for about two months, there is visible and encouraging thickening of my hair, some regrowth does seem to be occurring. And now that I'm on HRT, I'm hoping I will get an additional boost from no longer losing hair.
