I tried Nioxin because a have always had thin hair(23 years old), its in my genes. But after my last pregnancy i noticed my hair was extremely thin, i could see my scalp through my hair everywhere. A friend recommended it to me (her mother uses it) and i have hed great sucsess. But I do other things to improve my hair. I use the complete line shampoo, conditioner, and leave in. i massage my head regularly, once a week i go to sleep with olive oil in my hair (put a towel down on your pillow case) i take vitamins for hair skin and nails everyday, and i also try to eat more lean protien and drink soy milk (soy is excellent for your body). I blow dry my hair everyday, i know this isnt good, but i dont look good with out it. anyways, with this combination, i have actually had new hair growth! I have bangs, and if you pull them back you can see a whole new line of hairs coming in,(about 1/4 inch long) i do not have breakage at this point because i rarely wear my hair back, these are new hairs! i also had a "bald spot" on the back of my head that was really noticeable that is now going away. i doubt that i will ever have a head of thick lucious hair like i want, but i do see a huge difference and it makes me more confident. I bought nioxin at jcpenny hair salon, the set cost me $37, I have been using it for about 1 month and i still have some left in the bottle. For that much money, im really happy. I have tried every product in the world. some are bad, some can style your hair really nice, but this is actually solving the problem. thanks nioxin. for a special ocassion, if i want really big hair, i use KMS amplifying mousse, i like this stuff too.
