Is Belle Color safe for sensitive or dry scalps?

While Belle Color delivers effective colour, its ammonia and p‑phenylenediamine can irritate sensitive or dry scalps, so a patch test is recommended and those with reactive skin may prefer an ammonia‑free alternative.

What does p‑phenylenediamine (PPD) do in Belle Color?

PPD is the primary oxidative dye precursor that reacts with hydrogen peroxide to form the pigments responsible for the final hair colour, enabling a broad spectrum of vivid shades.

How often should Belle Color be applied, and does it contain any controversial chemicals?

Belle Color is a permanent dye intended to be reapplied every 4‑6 weeks as hair grows out, and its formula includes ammonia, hydrogen peroxide and PPD, which are effective but have been criticized for potential irritation and allergic reactions, so proper ventilation and protective measures are advised.
