Suitable for dry, damaged and colour-treated lengths, the Nioxin System 3 Scalp + Hair Conditioner nourishes the hair while lending a thicker, fuller look. Enriched with biotin and niacinamide, the formula plumps the fibres with moisture to protect against breakage and visible brittleness, supporting the feel of stronger strands with more noticeable volume and body. This conditioner is designed to be used as part of the brand’s System 3 shampoo, conditioner and treatment set for optimal results.
