How do I know which System Kit is right for me?

For natural, untreated hair with light thinning, we recommend System Kit 1. For natural, untreated hair with progressed thinning, we recommend System Kit 2. For damaged, dry, or colored treated hair with light thinning, we recommend System Kit 3. For damaged, dry, or color treated hair with progressed thinning, we recommend System Kit 4.

How do I know which kit to use if I previously used System Kit 5 or 6?

What does Nioxin System 1 Shampoo do?

Nioxin System 1 Shampoo gently cleanses the scalp and hair, helping remove impurities and excess sebum to support a healthy scalp environment. It is designed for natural, untreated hair with light thinning.

What are signs of light thinning?

Light thinning can show up in subtle ways. You may notice more hair in your brush or shower, your hair may feel less full than it used to, your ponytail may seem smaller, or you may be seeing early signs of reduced hair density.

Can I use System 1 on color-treated hair?

Nioxin System 1 is specifically formulated for natural, untreated hair with light thinning. If your hair is color-treated, highlighted, bleached, or chemically processed, we recommend System 3, which is designed for dry, damaged or color-treated hair with light thinning.
