Designed to remove oil and debris such as sebum, fatty acids and environmental residue which can block hair follicles, the System 1 Cleanser Shampoo by NIOXIN is suitable for normal to fine, thin looking natural hair. It gently removes product build up, clearing nutrient pathways to your scalp and hair follicle sites without stripping hair of essential oils. Unique technology BioAMP® helps to provide thicker looking locks by reducing hair loss and increasing the fullness of each hair strand, whilst the Transactive Delivery System® uses antioxidants, botanicals and vitamins to deeply cleanse for a rejuvenated feeling. The first of three steps towards a healthy scalp and thicker looking hair, the cleanser shampoo will amplify hair texture whilst refreshing the scalp with Activ-Renewal® technology containing white tea extract and peppermint oil. You'll be left with a healthy shine and fuller hair texture. K.D. Directions for use: Apply to wet hair. Gently massage into scalp and hair. Lather and rinse.
