Is Nutrisse 9 Meget Lysblond suitable for sensitive scalps or already damaged, color‑treated hair?

The formula contains ammonia, hydrogen peroxide, resorcinol and fragrance, which are common culprits for scalp irritation and can exacerbate damage, so a patch test is recommended and the product should be used sparingly on fragile or chemically‑treated hair.

What function does resorcinol serve in the Nutrisse 9 colour cream?

Resorcinol acts as a coupling agent in oxidative hair dyes, reacting with the peroxide‑generated radicals to help develop the final blonde shade; while effective for permanent colour, it can be a sensitising ingredient for some users.

How frequently should the dye be applied and are there any controversial ingredients to be aware of?

Professional recommendations suggest using the product only when a colour refresh is needed, typically every 4–6 weeks, and note that it contains ammonia, hydrogen peroxide, p‑aminophenol, nano‑silica and synthetic fragrances, ingredients that some consumers consider controversial due to irritation or safety concerns.

Product Insights

Nutrisse 9 Meget Lysblond is a L’Oréal professional hair‑colour cream designed to achieve a very light blonde shade, formulated with a blend of conditioning agents such as cetearyl alcohol, shea butter and plant oils, as well as antioxidants like ascorbic acid and tocopherol to help protect the hair shaft. The dye relies on traditional oxidative chemistry, containing ammonia, hydrogen peroxide, p‑aminophenol, m‑aminophenol, resorcinol and various synthetic colorants (e.g., CI 77891 titanium dioxide, CI 15985, CI 19140) which can cause scalp irritation or allergic reactions, especially in sensitive users. The product is labeled gluten‑free but includes fragrance, several preservatives, and a nano‑silica component, so individuals with fragrance sensitivities, soy allergy (soybean oil is present), or concerns about nanoparticles should use it with caution.

Comparative Analysis

Within the professional hair‑colour segment, Nutrisse 9 Meget Lysblond stands out as a high‑coverage, ammonia‑based dye targeting very light blonde shades, positioning itself above conventional permanent dyes in terms of lift and intensity.
