Is Natural & Easy 545 Blond Cendré suitable for sensitive scalps or color‑treated hair?

The dye uses ammonia and sodium laureth sulfate to open the cuticle, which can be harsh on sensitive scalps or already chemically‑treated hair; while conditioning ingredients like cetearyl alcohol and olive oil help soften the hair, a patch test is advisable and those with known sensitivities should consider a gentler, ammonia‑free option.

What is the function of ammonia (ammonium hydroxide) in this hair color?

Ammonia raises the hair's pH, swelling the cuticle and allowing the pigment molecules to penetrate; it also enables the peroxide developer to oxidize the dye precursors, ensuring a permanent color fixative.

How often should Natural & Easy 545 Blond Cendré be used and are there any controversial chemicals to be aware of?

The product is intended for reapplication every 4–6 weeks to maintain color vibrancy; it contains controversial ingredients such as ammonia, resorcinol, toluene‑2,5‑diamine sulfate and fragrance, which may cause irritation or allergic reactions in susceptible individuals.
