Oliver Sutherland –
After using the Nioxin System 4 Trial Kit for four weeks, I noticed a visible increase in hair fullness. My thinning areas seem less noticeable, especially at the crown. The shampoo and conditioner are easy to use and don’t leave residue. I would recommend this to anyone with fine, chemically treated hair.

The serum helped improve the texture of my hair. I used it every day after washing and felt a difference in volume within two weeks. The product is effective, though it takes time to see full results.
