Shopping details

Kérastase gave us the volume. ARGELAN gave us a softer, more natural-looking finish. Both earned 4.5/5, for different reasons. These bottles belong in the same story because we used Kérastase first, then decided to try ARGELAN. Curiosity was the reason for the change; Kérastase still had plenty to recommend it.

Two of us used these products: Kérastase for one month, then the ARGELAN pairing for several weeks, with use still ongoing. The impressions and scores here come from the owner’s account of that shared routine. Each score is one personal assessment of the option as used, rather than an average of two separately collected ratings.

The starting point was Kérastase Genesis Homme Bain de Masse Épaississant. The next chapter paired ARGELAN Bouncy Up Organic Shampoo with ARGELAN Moist Glow Organic Treatment. That last bottle is the rinse-out conditioning step. The two ARGELAN bottles are from different lines, brought together in our routine.

Kérastase Genesis Homme: the volume is the appeal

The clearest impression of Bain de Masse was simply how good the volume looked. It gave hair the fuller appearance we enjoyed, and that is the reason it remains such a good reference point in this comparison.

Kérastase positions this particular Genesis Homme shampoo around thickness and volume. Our observation is narrower and more personal: we liked the visible volume after using it. We did not measure changes to individual strands or assess hair growth.

The exact name matters when shopping. Bain de Masse Épaississant is the photographed bottle. Other Genesis Homme shampoos can look similar on a results page, so check the product name as well as the green packaging.

ARGELAN: soft hair that still looks like your own

ARGELAN felt very soft. The finish was natural and understated, almost as though the hair had not just been washed. That describes the appearance and feel we liked: there was less of an obvious freshly washed transformation.

It is a useful distinction if you are deciding what you want from wash day. Sometimes the pleasure is noticeable volume. Sometimes it is hair that feels comfortable and looks entirely at ease. Our ARGELAN pairing suited that second mood beautifully.

Bouncy Up is itself positioned by ARGELAN as a volume-oriented range. The softer impression here comes from our experience with this shampoo and the Moist Glow conditioning treatment together. It should not be read as a claim about every person’s result from Bouncy Up used alone.

Is ARGELAN Bouncy Up sulfate-free?

Yes: ARGELAN lists Bouncy Up as sulfate-free on its official haircare page. The published shampoo ingredient list includes sodium C14-16 olefin sulfonate; its name should not be confused with a sulfate. Sulfate-free also does not mean that a shampoo has no cleansing ingredients.

That answers the question raised by the soft feel, without turning a personal sensation into a test of cleansing strength. The Kérastase global ingredient list we checked includes ammonium lauryl sulfate. Formulas can differ between markets, so the ingredient list on the bottle you are buying takes priority.

The scent that stays with you

Fragrance was part of the pleasure of both options. Our scent memory was natural-smelling, pleasant and lingering, with an association that leaned towards ginger.

The labels make a useful distinction from that personal impression. Bouncy Up names Atlas cedar and clary sage; the photographed Moist Glow treatment names geranium and chamomile. Ginger is our sensory association, not the advertised fragrance of those ARGELAN bottles. The Kérastase label does name ginger root, although an ingredient on a label does not tell the whole story of how a fragrance smells.

A leathery detour with Kérastase

We also experimented with adding an oil we know as “Safrolin” to the Kérastase bottle. The resulting leathery scent was a pleasure in its own right. That leather note belongs to our altered bottle, rather than the original shampoo. The owner describes the addition as an essential oil; its precise identity and composition have not been independently verified. This is a scent anecdote, not a mixing recommendation.

Why both earned 4.5/5

Kérastase is the one we remember for the volume. ARGELAN is the pairing we remember for its very soft feel, natural finish and lingering scent. Trying the latter did not diminish what we liked about the former.

The ARGELAN score belongs to the combination we used. It is not two separate ratings for the shampoo and treatment, and it does not assess the newly listed version of Moist Glow. Our bottle says 97% natural-origin ingredients; ARGELAN’s current Japanese page displays 98% for the treatment. The shopping note below keeps that edition difference visible.

For the next step after washing, our Glaze Milk guide looks at a leave-in styling spray. If your question is how to refresh curls between washes, ALAMA Curl Re-Activator belongs to that different part of the routine. Choose the step for the finish you want to live with.
