The Nioxin System 4 is a protective hair treatment specially developed for coloured and damaged hair with advanced weakening. This product comes in a 100 ml serum with a convenient dispenser pump, allowing precise application and optimal preservation of the product. Formulated in Germany, the serum contains a combination of emulsifiers and preservatives such as Polysorbate 20, Polysorbate 60, Polysorbate 80, and Potassium sorbate, which ensure stability and promote effective absorption into the hair. The composition is suitable for unisex use and meets the specific needs of chemically treated hair, with a thickening effect that helps strengthen weakened hair fibres and improves the texture and resilience of coloured hair exposed to damage and brittleness. The serum form ensures even distribution without adding unnecessary weight, ideal for daily use that protects and revitalises the hair. Although it does not contain an SPF filter, it is a good addition to hair care routines that require protection and repair, especially for hair exposed to colour treatments and external aggressions. In summary, Nioxin System 4 offers a technical and targeted solution for coloured hair with advanced damage, providing density and protection through a concentrated and easy-to-apply treatment.
