Is Excellence 10 Ekstra Lys Blond safe for sensitive scalps or chemically damaged hair?

The product contains ammonia, hydrogen peroxide and p‑phenylenediamine‑derived dyes, which are known irritants; users with sensitive skin or heavily processed hair should perform a patch test and may prefer milder, ammonia‑free colour alternatives.

What role does hydrogen peroxide play in this hair colour formula?

Hydrogen peroxide acts as an oxidising agent that opens the hair cuticle and reacts with the dye precursors (such as p‑phenylenediamine, resorcinol and m‑aminophenol) to develop the extra light blond shade and lock the colour in the hair shaft.

Does this formula include any controversial or allergenic ingredients?

Yes, it lists several potential allergens and controversial chemicals, including ammonia, toluene‑2,5‑diamine, m‑aminophenol, resorcinol, fragrance (parfum), nano‑silica and titanium dioxide, all of which can cause allergic reactions or irritation in susceptible individuals.

It also contains fragrance, nano‑silica, titanium dioxide and several known allergens (e.g., resorcinol, m‑aminophenol), so a patch test is recommended before full application.
