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.

Do Nioxin System Kits contain minoxidil?

No, the Nioxin System Kits are not formulated with minoxidil. Instead, they are powered by a unique blend of Niacinamide, Caffeine, Salicylic Acid, and Peppermint Oil to strengthen, thicken & boost hair density, with visible results in 30 days*.

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

We recently transitioned from 6 kits to 4 to make it even easier to navigate which kit will help you meet your hair goals. If you previously used System Kit 5, we recommend using System Kit 3. If you recently used System Kit 6, we recommend using System Kit 4.

How often should I use the 3-step system to see results?

We recommend using the complete system at least 3 times a week for visible results in 30 days.

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.

How is thinning different from hair fall?

Hair fall refers to the shedding of individual hair strands, which is a normal part of the hair growth cycle. Hair thinning refers to a gradual reduction in hair density, which can make hair feel less full over time. Signs of thinning may include a smaller ponytail, less volume, or reduced hair density.

Can I use System Kit 3 on natural, non-color-treated hair?

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

What products should I use with System Kit 3?

For a complete thinning hair routine, pair System Kit 3 with Night Density Rescue Serum® for overnight scalp and hair care support or Diamax Advanced® Hair Thickening Serum for instantly thicker-looking hair. For additional strengthening benefits, add the Anti-Breakage Strengthening Mask to your weekly routine.
