Is the Excellence Creme Ultra 5.11 safe for sensitive scalps or dry hair?

The formula contains ammonia, hydrogen peroxide and fragrance, which can cause irritation on sensitive scalps, so it is best suited for normal to resilient scalp types and may be too harsh for dry or highly sensitive scalp conditions.

What function does ammonium hydroxide serve in this permanent hair color formula?

Ammonium hydroxide raises the hair cuticle pH to allow the color pigments to penetrate and react with the hydrogen peroxide developer, enabling permanent color deposition.

How often should the product be applied, and does it contain ingredients that may cause irritation or are restricted in certain regions?

The cream is intended for a single application during each coloring session, typically every 4-6 weeks for touch-ups, and it includes potential irritants such as ammonia, resorcinol, and fragrance, which are regulated in some markets and may be unsuitable for users with known sensitivities.

Product Insights

Excellence Creme Ultra 5.11 Ash Light Brown is a permanent hair color cream from L'Oreal Norway, designed to deliver an ash light brown shade. The formulation combines water, cetearyl alcohol, propylene glycol, conditioning agents such as polyquaternium-22, and a hydrogen peroxide/ammonium hydroxide oxidative system; it also contains colorants (CI 77891/Titanium Dioxide and other proprietary dyes), silica nanodispersions for smoothness, fragrance, and is labeled gluten-free. It provides long-lasting, even color with conditioning benefits, but potential irritants include ammonia, hydrogen peroxide, resorcinol, and fragrance, making it unsuitable for sensitive scalps or those with fragrance allergies.
