Hair loss is one of the most emotionally challenging beauty concerns women face.
Unlike wrinkles, which tend to appear gradually, increased shedding can feel sudden and alarming. Whether it's post-partum hair loss, stress, hormonal changes, weight loss medications, seasonal shedding or simply age-related thinning, most women want the same thing:
Less hair in the shower. More hair on their head.
Vichy's latest Dercos Aminexil Clinical R.E.G.E.N. Booster promises exactly that.
But does the formula justify the hype?
Key Active Ingredients Aminexil (1.5%)
The hero ingredient is Aminexil at 1.5%, one of the highest concentrations currently available in a dermocosmetic hair loss serum. Vichy has researched Aminexil for more than 30 years and positions it as its flagship anti-hair-loss molecule. It helps maintain hair anchorage by preventing excessive collagen stiffening around the follicle.
Compared with many hair loss serums relying mainly on botanical extracts, 1.5% Aminexil is a genuinely meaningful concentration.
Niacinamide
Niacinamide appears extremely high in the ingredient list, suggesting a substantial concentration. Vichy includes it as part of its 3% Revitalizing Essence. Niacinamide helps soothe the scalp, support barrier function and reduce micro-inflammation that can negatively impact follicle health.
Ginger Extract
Ginger extract provides antioxidant support and is intended to help restore the regenerative potential of the hair bulb. While ginger alone won't regrow hair, it complements Aminexil by helping create a healthier scalp environment.
Caffeine
An interesting addition is caffeine, which may help stimulate scalp microcirculation and support hair growth pathways. Although caffeine isn't present at pharmaceutical levels, it's a welcome bonus ingredient in this category.
The Science Behind The Claims
The headline claim is impressive:
+14,000 hairs in 12 weeks.
According to Vichy, this result was observed in a clinical study involving 40 women and 37 men using the serum at least five times per week over 12 weeks. The brand also reports improved scalp coverage, stronger hair fibres and visibly denser-looking hair.
As always, these numbers should be interpreted carefully. Not every user will gain exactly 14,000 hairs.
However, the fact that Vichy conducted a controlled clinical study puts this product above many "miracle hair growth" serums that rely solely on marketing claims.
Texture & Application
One of my favourite aspects of this serum is how lightweight it feels.
Many anti-hair-loss products leave the roots sticky, greasy or difficult to style.
This one absorbs surprisingly fast and leaves virtually no residue. The formula is designed for daily use on either dry or damp scalp and doesn't require rinsing.
For women with fine hair, this is a major advantage.
Is It Suitable For Post-Partum Hair Loss?
This is probably one of the strongest target groups for this product.
Although no topical serum can completely stop post-partum shedding, Aminexil is one of the few non-prescription ingredients with meaningful clinical data behind it.
Women experiencing temporary shedding after pregnancy, significant weight loss or stressful periods may benefit from using it consistently for at least three months.
How Does It Compare To Competitors?
Compared to many pharmacy hair serums:
Product Type Typical Active Level Botanical Hair Serums Mostly plant extracts Rosemary-Based Products Variable potency Aminexil Clinical Products 1.5% Aminexil Prescription Minoxidil Stronger clinical evidence
Minoxidil remains the gold standard for regrowth.
However, many women dislike:
Initial shedding phase Scalp irritation Daily commitment Texture issues
For those users, Vichy offers an excellent middle ground between cosmetic and pharmaceutical treatment.
Is The Price Fair?
The serum usually retails around €45–60 for 90ml.
That isn't cheap.
However, considering:
1.5% Aminexil High niacinamide placement Additional ginger extract Clinical testing Daily-use volume
I would consider it fairly priced within the premium pharmacy category.

Final Verdict
Vichy has created one of the most scientifically credible non-prescription hair loss serums currently available.
The 1.5% Aminexil concentration is genuinely impressive, the formula feels elegant on the scalp, and the clinical data supporting the product is stronger than what we see from most competitors.
Will it completely reverse advanced hair loss?
No.
But for women experiencing increased shedding and early thinning, it is one of the best pharmacy options currently available.
Final Score: 8.9/10
