Well I am definitely not back to 100% when it comes to my hair. It's pretty good now compared to the worst point, but it was still much thicker when I was 36. I am at 8 months into treatments, so realistically, I should have about 4-8 more months of improvement based on the hair count studies regarding Finasteride.
Nizoral is an anti-fungal shampoo and the ingrediant is called KETOCONAZOLE and it is a member of the AZOLE family of drugs which have been studied and found to have some anti-androgen effects topically. The shampoo is found at 1% concentration in most retail type stores like WallMart, etc. The 2% version is prescription, but most people order it online anyway. I personally quit the shampoo and started using a CREAM version a few weeks ago. It is simply NIZORAL CREAM and if you search, you will find it too online. MICONAZOLE is another AZOLE drug that seems to work well and adds synergism to the BIG 3 meds. Miconazole has tons of threads about it right now and MOST people are getting some results including faster growing hair and new growth as well as thickening of finer hairs. I KNOW it has really sped up my progress and it is OTC and EASY to get. It's actually usually sold as "Vagina Cream" for fungus infections!!! LOL!
Here is a pic of me at 36, almost 37 and this is the desity I am trying to achieve. I'm about 75% there.
As far as "maintaining" on the Big 3... Well, it's FOREVER. If you quit, your hair goes away again. It's worth it, though and not that difficult to maintain.
