Growth Kit

Shampoo first, mask second. Shampoo cleanses the scalp deeply, which allows the mask's active ingredients to penetrate the fiber more effectively.

Apply the mask to wet hair after shampooing, leave on for at least 15 minutes, then rinse thoroughly.

Yes.

The shampoo bottle contains 500 ML and lasts between 3 and 4 months if you wash your hair 2 to 3 times per week.

The mask also contains 500 ML and will last you for at least 3 months at the same frequency.

As for the gummies: there are 90 of them and you need to take 1 per day — so that lasts 3 months.

2 to 3 times a week is the ideal frequency for most hair types. For very dry or thick hair, 1 to 2 times is enough. For fine, oily-prone hair, 3 times a week is generally more suitable.

A single application is sufficient for each wash.

Yes, our products are suitable for colored, bleached, and blonde hair. They do not alter the color and do not interfere with ongoing treatments.

If you have just colored your hair, wait 48 to 72 hours before the first use to allow the color to set.

Yes, you can use the routine with a smoothing treatment. There are no contraindications.

However, the sulfate present in our shampoo may reduce the longevity of the smoothing treatment—it affects the keratin deposited during the treatment. If you wish to preserve your smoothing treatment for as long as possible, you can use only the mask during this period and incorporate the shampoo once the smoothing effect has faded.

No — and that is often the first surprise for our clients. The formula has been specifically developed so that the garlic scent is completely masked. The result: a soft, clean scent that our clients love.

No trace of garlic scent remains in the hair after rinsing.

The routine is designed to be complete and sufficient on its own — it covers both external action (shampoo + mask) and internal action (gummies) to meet all expectations: growth, density, shine, and anti-hair loss.

There are no contraindications to combining it with other treatments if you wish. To clearly measure the effects of the routine, we simply recommend using it alone for the first 4 weeks.

Yuka is a useful tool — but it has an important limitation: it flags the presence of an ingredient without taking into account its actual concentration or the context of use (whether the product is rinsed off or not, duration of contact). An ingredient can be rated red even at minute doses, well below any threshold of concern.

Our shampoo scores 51/100 — "Good". This is a good score for an active shampoo: most comparable anti-hair loss shampoos score between 25 and 45.

Our mask scores 19/100. This score reflects the presence of silicones and a preservative — two ingredients that we explain in detail below. It does not reflect a real risk in the context of this product's use.

Our priority is effectiveness. We considered removing sulfate, but after consulting our scientific teams, we concluded that this would have had negative impacts on growth: a poorly cleansed scalp accumulates sebum residue, styling products, and pollution, which clogs follicles and directly hinders hair growth. That was not an acceptable compromise.

The Sodium Laureth Sulfate (SLES) we use is the most effective surfactant for deep-cleansing the scalp. It is precisely because it works so well that it contributes to growth—and that is why we have kept it.

Its safety is established by the FDA, the European Commission, and all independent scientific committees for rinse-off formulas at standard concentrations. A shampoo is exactly that context: brief contact, thorough rinsing.

Phenoxyethanol is a preservative: without it, any formula containing water would be exposed to the growth of bacteria and mold. It is what ensures the product’s safety and shelf life.

Our mask contains it at 0.30%—which is three times below the limit authorized by European regulations (1%). At this concentration, in a rinse-off product, the European Scientific Committee on Consumer Safety (SCCS) considers it safe for all adults.

Manufacturers always use the lowest effective concentration possible to ensure optimal preservation while minimizing exposure. 0.30% is precisely that threshold—sufficient to protect the formula, and well below any cause for concern.

The real concern regarding this ingredient relates to leave-on products that remain on the skin all day. Our mask is a rinse-off product—it is in contact for a few minutes, followed by a complete rinse.

The silicones we use—Dimethicone and Amodimethicone—are among the most effective active ingredients in hair care for three specific properties: shine, softness, and breakage reduction.

Amodimethicone in particular is recognized by formulators for its ability to target damaged areas of the fiber, reduce the force required for detangling by more than 80%, and provide greater light-reflecting properties than other conditioning agents. Dimethicone, for its part, creates a coating film that protects the fiber from friction and retains moisture.

Mechanical breakage is one of the most underestimated causes of hair that seems not to grow. These two active ingredients address this directly.

These are rinse-off silicones—designed to be rinsed away, not to remain on the fiber or the scalp. Yuka rates all silicones the same way without making this distinction. A properly rinsed silicone does not accumulate and does not clog follicles.
