Dessange Nutri-extrême Richesse is a basic conditioner hiding behind a luxe name

Dessange positions Nutri-extrême Richesse as a richly nourishing treatment for dry, damaged hair, but the verified INCI reads as a standard supermarket-tier conditioner dressed up with a splash of sesame and evening primrose oil. It will smooth and detangle competently. It will not transform anything.

What it is

A rinse-out conditioner aimed at dry or chemically processed hair. The marketing leans on sesame seed oil and evening primrose (Oenothera biennis) oil for the 'nutrition' story, but on the actual list sesame sits after the dyes and titanium dioxide, and evening primrose sits after phenoxyethanol — meaning both are present in cosmetically token amounts, not treatment-level doses.

The base is what's doing the real work: water, cetearyl alcohol (a fatty alcohol that conditions and thickens), paraffinum liquidum (mineral oil) for slip and occlusion, and dipalmitoylethyl hydroxyethylmonium methosulfate, a quaternary conditioning agent that helps the formula cling to the hair shaft.

Key ingredients

Amodimethicone is the most useful functional ingredient here. It's a substantive, amine-functional silicone that deposits selectively on damaged areas of the cuticle, so it smooths split-prone ends without building up as aggressively as straight dimethicone. Paired with cetrimonium chloride, you get reliable detangling and static control — this is competent shelf-conditioner chemistry. Cetyl esters add a light emollient feel; trideceth-6 is there to help solubilize the silicone and fragrance.

The downsides are mostly cosmetic philosophy. The fragrance load is heavy and the INCI declares six EU-listed allergens: alpha-isomethyl ionone, coumarin, butylphenyl methylpropional (lilial — now banned in EU cosmetics due to reproductive toxicity concerns, and a notable red flag if you bought a recent batch), benzyl benzoate, benzyl salicylate, and benzyl alcohol. Anyone with a scalp prone to contact dermatitis should skip this outright.

Two azo dyes (CI 19140 / Yellow 5 and CI 15985 / Yellow 6), titanium dioxide, and mica are present purely for aesthetics — to make the product look creamy and golden in the tub. Fine, but it tells you where the formulation budget went. Chlorhexidine digluconate also appears, which is unusual in a conditioner; here it works alongside phenoxyethanol as a secondary preservative. Not a problem, just notable.

Who it's for

If you have coarse, dry, or color-treated hair, tolerate fragrance well, and want a cheap, easy-to-find conditioner that delivers softness and slip, this does the job. The mineral oil and amodimethicone combination is genuinely effective at making rough hair feel smoother in the shower and easier to comb.

Skip it if you have a sensitive or itchy scalp, if you're fragrance-avoidant, or if you were drawn in by the 'nutri-extrême' framing expecting a treatment-level product. This isn't a mask, it isn't a leave-in, and the headline botanical oils are present in trace amounts.

The verdict

Nutri-extrême Richesse performs adequately as a daily conditioner but doesn't justify the 'extrême' in the name. At drugstore prices it's defensible; at salon prices it's not. The presence of butylphenyl methylpropional in particular suggests an older or non-EU-compliant formulation, which is worth checking before you buy. For dry, damaged hair you'll get more out of a dedicated mask (K18, Olaplex No. 8, or even the Garnier Ultra Doux range) used weekly, paired with a cheaper, lower-fragrance daily rinse-out.
