Offering visible results in as little as 30 days, the Nioxin System 3 Scalp + Hair Thickening Treatment encourages fuller, thicker-looking hair with added body and shine. Enriched with biotin and niacinamide, the serum lends non-oily moisture to the scalp and strands, helping to plump them and promote a more voluminous illusion. Biotin protects against breakage and noticeable brittleness, leaving the hair with a stronger feel over time, alongside a reduced appearance of split ends and dryness. Suitable for fine, fragile and colour-damaged lengths, use the serum daily in conjunction with the brand’s System 3 shampoo and conditioner for optimal results.
