Am a Nioxin convert
I started using all Nioxin 3 products one month ago; shampoo, conditioner, scalp treatment, volumizing thickening spray and extra hold hairspray. Since I use them all together, it's hard to say specifically if one of the products works or doesn't. In my honest opinion, the Nioxin line has improved t...

more hair shedding
I have thinning hair in the frontal region. My hair part isn't noticeably thinning, but it could be better. I attribute my hair loss to genetics.

Definitely Helped my Fine Hair
Hair Type Straight Hair
Took about a month to notice any difference in hair thickness. It does help with regrowth. I purchased my second bottle recently. A little goes a long way.
After a few months, I can see a difference!
I used Nioxin shampoo and conditioner a few times a week for several years but didn't really notice a difference in how much hair I was ahedding daily. This Fall Defense shampoo made an instant difference in the amount of hair i shed daily and in the shower. Instead of picking up a few hundred hairs out if the drain, I pick up about 20. I also have regrowth all over my head, and can see the three and four inch hairs all over my head. My ponytail is thicker, and my hair has more body. I lost a lot of volume the last few years, after an extended illness, and after using this shampoo for four months, I'm a believer.
Scalp care hero!
Ive been on a scalp care mission….this shampoo removes all crap / oil from my scalp….the best part is that it does so without stripping my hair! Multiple hair-growth support ingredients. Let it sit on ur scalp for a few minutes and voila! Clean/healthy scalp and hair! Ive tried tons of shampoos - this one is my desert island must-have.
