Is Excellence 4 Brun safe for sensitive or damaged scalp and hair?

The product is formulated with conditioning agents that can be gentle on normal hair, but the inclusion of chlorhexidine digluconate, fragrance and other synthetic preservatives may trigger irritation in sensitive scalps; a patch test is strongly recommended.

What role does hydrolyzed oats play in this hair-colour formula?

Hydrolyzed oats supply oat proteins and beta-glucans that help moisturise, soothe and reinforce the hair cuticle, reducing dryness caused by the oxidative dyeing process.

Q: How often should Excellence 4 Brun be applied and does it contain any controversial chemicals?

The dye is intended for use only once per colour cycle, typically every 4-6 weeks, and it includes ingredients such as chlorhexidine digluconate, hexadimethrine chloride and synthetic fragrance, which are considered controversial due to possible irritation and environmental concerns.

Product Insights

Excellence 4 Brun is a permanent brown hair colour from L'Oréal that combines a high level of conditioning agents, such as hydrolyzed oats, cetearyl alcohol and polyquaternium-22, to help protect the hair shaft during the bleaching process. The formula also contains several synthetic components, including chlorhexidine digluconate, hexadimethrine chloride, multiple fragrance agents, and titanium dioxide (CI 77891), which may cause scalp irritation or allergic reactions in sensitive users. Additionally, the presence of animal-derived or ambiguous ingredients leaves its vegan status uncertain.

Comparative Analysis

Excellence 4 Brun targets the premium segment of brown hair-dye consumers by offering a long-lasting colour with added conditioning benefits, distinguishing itself from organic or low-chemical alternatives that prioritize natural ingredient profiles.
