Kératine Color Châtain Doré 5.5

The Keratin Color Châtain Doré 5.5 is a permanent hair dye from Schwarzkopf that delivers a warm chestnut gold shade while incorporating keratin to help reinforce the hair shaft. The formulation relies on classic hair‑color chemistry, including ammonia, hydrogen peroxide, and p‑phenylenediamine, which provide lasting colour but can irritate sensitive scalps or trigger allergic reactions. The product is supplied as a multi‑component kit (60 ml + 60 ml + 22.5 ml + 12 ml) packaged in a cardboard box with plastic containers, making it convenient for home use but contributing to plastic waste.
