Water (and) Glycerin (and) Sodium Metabisulfite (and) Glycine (and) Larix Europaea Wood Extract (and) Zinc Chloride (and) Camellia Sinensis Leaf Extract
Capixyl™ is a complex composed of a biomimetic peptide and red clover extract. It works at the root of the problem: it stimulates stem cell regeneration, and strengthens hair anchorage by increasing follicle size.
Our Capixyl is formulated at 5%, the maximum percentage recommended for intensive action (preventive dosage: 0.5–2.5%; intensive dosage: 2.5–5%).
Butylene Glycol (and) Water (and) Dextran (and) Acetyl Tetrapeptide-3 (and) Trifolium Pratense (Clover) Flower Extract
Baicapil is an energy complex composed of three plant ingredients: Baikal skullcap, wheat germ, and soybean. It provides essential sugars to the hair follicle, thus contributing to increased cellular activity.
It acts on two levels:
As a protective source, reducing hair loss
As a source of energy, stimulating their growth
Thus, Baicapil prolongs the anagen phase (active growth phase) of the hair.
Our Baicapil is included at its optimal effective concentration (4%), shown to deliver the best results in clinical studies.

Saw palmetto, also known as dwarf palm, is a plant that promotes hair growth by helping to reduce DHT, a hormone that shrinks hair follicles and leads to progressive hair thinning.*
Our Saw Palmetto is dosed at 320 mg per day, with 45% fatty acids, the most clinically studied concentration for its effects on hair loss.
Why 320 mg of Saw Palmetto?
This is the dosage used in the reference clinical studies on hair loss, which shows measurable effects on hair density and cycle. Below this dosage, the inhibitory effect on DHT is insufficient to truly act on the follicles.
Why 45% fatty acids?
Fatty acids are the active ingredients in Saw Palmetto: they are responsible for inhibiting 5-alpha-reductase, the enzyme responsible for converting testosterone to DHT. A standardized extract of 45% guarantees that each dose contains the same active concentration, unlike non-standardized extracts, where the actual active content can vary threefold from one batch to another.
In summary:
320 mg is the effective dose. 45% fatty acids is the guarantee that this dose contains the right active ingredients. Both together replicate the conditions of studies that have demonstrated the effectiveness of Saw Palmetto on hair loss.

After 12 weeks:
Keranat® is a patented active ingredient derived from millet seeds, dosed at 80 mg in Grow No.1. Rich in sulfur-containing amino acids and structural lipids, it acts directly on the hair fiber to strengthen its resistance and help reduce breakage. At the scalp level, it supports the anchoring of the hair within the follicle and helps reduce hair loss. A comprehensive action from root to tip, for visibly denser and stronger-looking hair.
EMortal Pep [Hair] is a pea peptide-based active ingredient rich in phytonutrients. It helps prevent hair loss and stimulates cell regeneration. Clinical trials have proven its effectiveness.
Our EMortal Pep [Hair] is formulated at its optimal effective concentration (3%), as shown by clinical studies.
Propanediol, Water, Hydrolyzed Pea Protein
Stinging nettle is a plant rich in minerals and active compounds, traditionally used to support scalp health.
Comparative study:Caffeine 0.2% vs Minoxidil 5%
Conclusion :A 0.2% caffeine lotion is as effective as 5% minoxidil.
→ Difference of 1.09%
→ Non-inferiority demonstrated
Caffeine is an active ingredient that stimulates microcirculation in the scalp while slowing the effects of DHT, the hormone responsible for hormonal decline. At 0.2%, it blocks the enzyme 5-alpha-reductase (which converts testosterone into DHT), while improving the supply of nutrients and oxygen to the follicles.
Our caffeine is included at its clinically proven effective concentration (0.2%), demonstrating positive results in clinical tests.
Bamboo is a highly concentrated natural source of silica, a mineral essential to the structure of hair.
L-cysteine is a sulfur-containing amino acid essential to the structure of hair. A key component of keratin, it contributes to the strength, growth, and vitality of the hair fiber.
Our L-cysteine is dosed at 80 mg per day, within the range used in clinical research on sulfur amino acids and hair.
Biotin, also known as vitamin B8, is an essential vitamin that contributes to the maintenance of normal hair. It participates in the metabolism of nutrients necessary for the proper functioning of the body and plays an important role in hair health. Often incorporated into hair care routines, biotin is particularly valued for its action on the beauty and quality of the hair fiber.
Selenium is an essential trace element involved in protecting cells against oxidative stress.
Vitamin B6 plays an important role in protein metabolism, which is essential for the production of keratin, the main protein that makes up hair. It therefore contributes to the proper functioning of the processes necessary for the formation and maintenance of healthy hair.
Conclusion: Niacinamide derivatives have demonstrated a statistically significant increase hair density compared to placebo (p = 0.04)
Niacinamide (or vitamin B3) is a multifunctional ingredient recognized for its benefits in dermatology. Applied to the scalp, it soothes irritation, rebalances sebum production, and strengthens the skin barrier.
Our Niacinamide is formulated at an optimal dosage (2%), combining skin tolerance, anti-inflammatory effectiveness and sebum-regulating properties, without attacking the scalp.
Vitamin B9, also known as folic acid, is essential for cell division and tissue regeneration, key processes for hair growth.
Vitamin B12 plays a key role in the formation of red blood cells, responsible for transporting oxygen to the hair follicles. A deficiency can reduce scalp oxygenation, weaken the hair and accelerate its loss. By maintaining optimal B12 levels, a follicular environment favourable to healthy and lasting growth is supported.
Zinc bisglycinate is a highly bioavailable form of zinc, essential for many biological functions, including those related to skin and hair.
Magnesium plays a key role in stress regulation, one of the leading causes of hair loss. By supporting nervous function and cellular metabolism, it helps reduce the impact of chronic stress on the hair cycle, limiting the premature shift of follicles into the resting phase. Optimal magnesium levels help preserve density and maintain regular hair growth.
Vitamin B5, or pantothenic acid, plays a key role in the energy metabolism of hair follicle cells. By supporting energy production at the cellular level, it helps maintain an active hair growth cycle and strengthen the hair fiber from within.
Hormonal imbalances, stress, deficiencies, Grow No.1 targets the biological mechanisms involved in progressive thinning and hair loss for visibly denser, stronger hair.
DHT: one of the main causes of hair loss. Sensitivity or excess DHT shortens the hair's life cycle and leads to progressive miniaturization of the follicles, increasingly thin hair, and ultimately hair loss.
Our targeted ingredients: Saw Palmetto, Nettle, and Millet
Everyday stress, linked to the pace and demands of modern life, can be sudden or chronic. It can increase cortisol levels and disrupt hormonal balance, contributing to diffuse hair loss.
Our targeted ingredients: Magnesium
Hair follicles need nutrients to produce hair. An unbalanced diet or poor absorption can slow down growth and trigger premature hair loss.
Our targeted ingredients: Zinc, Selenium, Calcium, Vitamins B5, B6, B8, B9, B12
Stress, pollution, and daily aggressions increase oxidative stress. This weakens hair follicles and accelerates their aging.
Our targeted ingredients: Keranat®, L-cysteine, Bamboo

We recommend avoiding GROW No.1 during pregnancy or breastfeeding. It is best to consult your doctor before taking any supplement during these periods.
Our Saw Palmetto is dosed at 320 mg per day, with 45% fatty acids.
Why 320 mg of Saw Palmetto?
This is the dosage used in reference clinical studies on hair loss, which shows measurable effects on hair density and cycle. Below this, the inhibitory effect on DHT is insufficient to genuinely affect hair follicles.
Why 45% fatty acids?
Fatty acids are the main active compounds in Saw Palmetto: they help inhibit the activity of 5-alpha-reductase, the enzyme responsible for converting testosterone into DHT. A standardized extract containing 45% fatty acids ensures a consistent level of active compounds from one dose to the next, unlike non-standardized extracts, whose active compound content can vary considerably from one batch to another.
Yes, GROW No.1 addresses the main causes of hair loss (hormonal, nutritional, stress, lifestyle) and can therefore help reduce seasonal hair loss.
Yes. And it's important to clarify: all humans naturally produce DHT; it's a hormone present in all organisms. The difference lies in the level of sensitivity of the follicles to this hormone, which varies from person to person.
However, DHT is only one of the possible causes of hair loss. GROW No.1 was formulated to act on all the mechanisms involved: stress, nutritional deficiencies, fatigue, and lifestyle.
Yes, the formula is also suitable for men, as it targets the biological mechanisms involved in hair loss.
Yes, GROW No.1 can be taken in addition to other vitamins, but be careful not to exceed the recommended daily intake for certain vitamins and minerals.
The first visible results on hair density and strength generally appear after 4 weeks, and significant growth results can be seen from 3 months of regular treatment.
Yes, GROW No.1 is effective for all hair types: straight, wavy, curly, coily, or kinky.
Yes, the capsules can be opened and their contents mixed with a small amount of food or drink. However, avoid hot drinks so as not to alter the vitamins and active ingredients.
No. GROW No.1 targets scalp follicles. Facial and body hair are regulated by other mechanisms.
