Nioxin offers something other hair growth or thickening systems do not: A complete scalp and hair cleansing system built for both women and men.

The Nioxin System No. 4 is a specially formulated hair care method designed to add thickness to thinning locks. System No. 4 was created for those with colored hair experiencing progressed thinning.

*For natural, untreated hair and progressed thinning, we recommend checking out Nioxin System No. 2.

System No. 4 includes a complete hair care regimen of products including a Cleanser Shampoo, Therapy Conditioner, and Scalp & Hair Treatment. Use the products as follows::

• Start with the Cleanser Shampoo - Gently massage into hair and scalp. Rinse well. Use this product daily. This product is designed to remove any follicle clogging sebum, fatty acids, and environmental residues from both the scalp and hair. The Cleanser Shampoo also contains Pro-Color Shield Technology which helps protect your color longer.
• Scalp Therapy Conditioner - Apply directly from the scalp and smooth to the ends. Leave in for 1 to 3 minutes. Rinse. This product helps to provide hair resilience and control your hair's balance of moisture.
• Scalp & Hair Treatment - Shake well. Apply evenly to entire scalp. Do not rinse. This product increases the diameter of each strand and contains UV protecting ingredients for your locks. Avoid contact with eyes - If contact occurs, rinse eyes thoroughly with water. The Scalp & Hair Treatment may cause temporary redness to the scalp after application.
