Frequently Asked Questions
10,000 mcg is a measured dose that supports keratin synthesis at levels shown in peer-reviewed studies. Many store-brand formulas contain 1,000–5,000 mcg, which may not deliver the same support for hair and nail structure.
Please refer to the product label for the specific collagen type and source. Collagen provides amino acids like glycine, proline, and hydroxyproline that support connective tissue and skin elasticity.
Each bottle contains a 30-day supply when taken as directed (2 capsules daily). The 3-pack and 6-pack bundles offer savings and ensure continuous use, which is important for consistent results.
Why Croissance capillaire avancée – Capsules de biotine 10 00... works
A targeted blend of research-studied ingredients, formulated at the doses studies actually used — not the dusted-on amounts found in cheaper formulas. Every milligram is printed on the label so you know exactly what you are taking.
Simple daily routine
Prenez 2 gélules par jour avec un verre d’eau, de préférence pendant un repas pour favoriser l’absorption. La régularité est essentielle : la biotine et le collagène agissent sur plusieurs semaines, et non quelques jours, en favorisant la production naturelle de kératine et de protéines par votre organisme. Prenez-les à la même heure chaque matin pour prendre l’habitude. Ne dépassez pas la dose recommandée. Si vous devez effectuer des analyses de laboratoire prochainement, informez votre professionnel de santé, car des doses élevées de biotine peuvent fausser certains résultats sanguins.

Real Reviews From Supplement World Customers
"I'm 34 and my nails have always been brittle. After five weeks on this, they're growing faster and I haven't had a single break. My hairdresser even commented on the shine."
"I've tried four different hair vitamins over the past year. This is the first one where I actually see new growth around my hairline at week six. The capsules are easy to swallow too."
"I'm 29, and after eight weeks my barber noticed thicker hair texture. The price is steep but the dose is legit. I'm sticking with it for now."
"Six months postpartum, my hair was shedding everywhere. My OB cleared me to try this. Three months in, the shedding has slowed and I see baby hairs growing back along my part."
"I'm on my third month. My nails grow so fast now I have to trim them weekly, and my hair has that healthy bounce again. No weird aftertaste or stomach upset either."
"I didn't think supplements could make a real difference. But at 42, dealing with thinning hair, I gave this a shot. Week seven now and my ponytail feels thicker. I'm genuinely surprised."
"I've been taking this for ten weeks. My hair stylist asked what I changed – it's shinier and less prone to breakage. The high biotin dose really seems to make a difference."
"The ingredients are top-notch and I'm seeing results after a month. Only downside is the capsule size – they're a bit big for me. But the benefits outweigh that minor inconvenience."
