Nioxin Pro Clinical's System Kit 4 is designed for dry, damaged, coloured hair with progressed thinning.  Clinically and dermatologically tested, this shampoo nourishes and gently cleanses your hair to protect against follicle-clogging sebum, resulting in thicker, fuller hair.
Formulated with a powerful blend of niacinamide, biotin and caffeine to help nourish the hair root, stimulate hair follicles and strengthen the hair. 
The three-step regimen begins with the Scalp + Hair Shampoo. Start by applying it to wet hair, gently massaging it into the scalp and hair for one minute before rinsing thoroughly. This gentle cleanser works to remove buildup, including follicle-clogging sebum and environmental residues, preparing the scalp for the next steps.
For optimal results, use the Nioxin System Kit 4 daily.
