How to read the result

An ingredient list (INCI) is ordered by concentration: the first ones are the most concentrated. We take that into account.

🌿

The allies

Targeted actives, hydrating, soothing or nourishing agents: what supports the fibre and the scalp.

👀

The "worth watching"

Occlusive silicones, stripping surfactants, drying alcohols, certain preservatives, or fragrance for sensitive scalps.

📊

Concentration

An ingredient near the top of the list weighs far more than at the very end. We flag when a sensitive point is highly concentrated… or just a trace.

What we rely on

Every ingredient carries its level of evidence. When solid research exists, we cite it; when data is limited, we say so plainly.

A cosmetic wellness analysis. For advice personalised to your profile and progress, the Repousse app goes further.
