Based on its formula, is this product safe for sensitive or dry scalp?

The presence of ammonia, p‑aminophenol, resorcinol and fragrance can cause irritation on sensitive scalps, so it is best suited for normal to oily scalp types; those with dry or highly sensitive skin should perform a patch test or consult a professional before use.

What is the role and benefit of dimethicone in this hair colour formula?

Dimethicone acts as a silicone‑based emollient that forms a protective film on hair fibers, reducing friction during processing, enhancing shine, and helping to lock in moisture, which mitigates dryness caused by the strong chemical oxidisers.

What is the optimal application frequency for this product, and does it contain controversial chemicals?

Excellence 9 Meget Lys Blond is intended for a single application per colour change, typically every 4–6 weeks; it does contain controversial chemicals such as ammonia, resorcinol, and p‑aminophenol, so a thorough patch test and adherence to the recommended usage interval are essential.

Product Insights

Excellence 9 Meget Lys Blond is a professional‑grade permanent hair colour from L'Oréal designed to achieve intense lift and bright very‑light blonde shades. The formulation blends water, conditioning agents like cetearyl alcohol and dimethicone with alkaline compounds (ammonium hydroxide) and oxidative agents (hydrogen peroxide) to enable permanent dyeing, and it includes pigment carriers such as titanium dioxide for colour stability. Although the product is gluten‑free and contains conditioning polymers for smoothness, it also features fragrance, p‑aminophenol, resorcinol and nano‑silica, which may irritate sensitive scalps or cause allergic reactions.

Comparative Analysis

Positioned as a high‑performance, salon‑style permanent blonde hair colour, it stands out for delivering strong lift and lasting vibrancy while incorporating conditioning ingredients, yet it contains several potential sensitizers that differentiate it from milder, everyday hair dyes.
