Nioxin System 4 Scalp Care + Hair Thickening Leave-In Treatment For Colored, Dry, & Damaged Hair with Progressed Thinning Nourish & Boost Hair Density with Niacinamide & Biotin

LOVE this and can't go without. Wish it was the larger size that came in the set with the shampoo and conditioner. Certainly seeing a difference in my hair with continued use and pairing with the shampoo and conditioner.

I use this mainly in my roots and my hair feels so much fuller. I am very impressed with the product. The smell is a little off. Can’t explain it, but I would buy this product again. My hairdresser even noticed a difference.

I bought it at,first at the,Academy of Hair but it really dose make your hair grow .I started it in November and by December I could see hair growth.I use,the,shampoo and conditioner as well. My husband told me he could see it,so not just me thinking it was growing

Very sticky

Great to help thicken thinning hair at a great price.

Product came with cap not sealed. Both ends of box is ripped off and box is open. Hoping this is really the product.

I wasn't really sure if any of these hair growth products work or not. Given how expensive they are, it's not easy to just dive in. However, I figured if this works then it's worth the money. Just didn't want to see less and less hair on my head.The RESULT:After 3 months of daily use, I notice some very short hair on my head in some areas. Not sure if it was broken hair or new hair.After 4 months, I was convinced there was baby hair growing.After 6 months, definitely see improvement.After 8 months, definitely see more hair growing in more area of my head.So far so good.The CONS:The cost is relatively high.

This is the 2nd time I have had to use in my life and it works just as good 2nd time as it did 1st time.
