Nioxin Hair-Thickening System

For more than 25 years, the hair-minded scientists at Nioxin have worked to transform thinning hairs into fuller, thicker, and healthier follicles. These chemists created distinct formulas based on specific hair types, from normal to visibly thinning to chemically treated. Each system is infused with key herbs and botanicals that protect and moisturize scalps and follicles, creating a healthy environment for hair and flimsy french berets to thrive on.

This system helps achieve those results in two simple steps. First, a cleanser unclogs follicles and promotes scalp health by clearing sebum, fatty acids, and other residues from the hair. Second, a lightweight scalp-therapy conditioner works to strengthen hair and balance moisture levels, helping fragile strands recuperate from environmental damage and chemical treatments.

  • Two-part haircare system

  • Helps protect the scalp against damage from chemical treatments
  • Cleanser unclogs follicles by removing residues, sebum, and microscopic corks

I have very thin, baby-fine hair, and several hairstylists recommended that I use this brand of shampoos and conditioners - even hairstylists who did not sell the products, so they had no incentive to push the product. I've been using them for years and while nothing can change thin hair to thick hair with tons of volume, at least it gives me whatever advantage I can get.

I have used Nioxin for a number of years and this price is fantastic! The product Nioxin Hair Duo is great for hair thickening. My hairdresser recently asked me if I wanted to have her thin my hair and I laughed at her! No way are you going to thin my hair! I have very thick hair because of Nioxin Hair- Thickening System Duos!!

I use Nioxin as my main shampoo. I transfer the product into smaller bottles so it is easier to manage in the shower. Nioxin works for me.

I like Nioxin. My hair is thinning and this product helps reduce hair loss. I have been using Nioxin for about 2 years.

It certainly gives my hair body and softness. I am hoping it will let me keep more hair as I age.

Best deal I ever made and I would do it again if offered. Had told so many people that it was over by the time they found out.

Can't tell a difference in hair thickness. Feels nice on my scalp but doesn't seem to help thicken my hair.
