Wanda Vaughan –
After using the Nioxin System 4 trial kit for three weeks, I noticed my hair felt softer and fuller. The shampoo cleanses well without stripping moisture, and the treatment left my hair with more body. It’s especially helpful for fine, chemically-treated hair.

I tried this kit because I had thinning hair after frequent coloring. The conditioner improved my hair’s manageability, and the treatment helped reduce frizz. I would recommend it to others with similar concerns.
