Is Olia Coloration Permanente Midnight Noir Saphir safe for sensitive scalps or color‑treated hair?

The dye contains several potential irritants, such as p‑phenylenediamine sulfate, m‑aminophenol, and sodium lauryl sulfate, which can trigger reactions on sensitive scalps; users with a history of dermatitis or allergies should perform a patch test before full application, but the included seed oils and vitamin E help mitigate dryness on color‑treated hair.

What role does p‑phenylenediamine sulfate play in this hair dye?

p‑Phenylenediamine sulfate is a primary intermediate that forms the dark pigment through oxidation with hydrogen peroxide, providing the intense midnight black color while also enhancing color fastness, but it is a well‑known allergen and must be handled with care.

How often should this permanent hair color be applied and does it contain any controversial chemicals?

Because it is a permanent formula, it is designed for use only once every four to six weeks to allow natural hair growth without over‑processing; the product does contain controversial chemicals such as p‑phenylenediamine, m‑aminophenol, and sodium lauryl sulfate, which are common in permanent dyes but may be avoided by consumers seeking allergen‑free or gentler alternatives.
