The Active Ingredient Is: Biotin (Vitamin B7)

Biotin, aka vitamin B7, is a water-soluble vitamin that helps with normal hair health and keratin production. This topical ingredient is used in beauty products to support the structural integrity of hair strands.

In this formula, biotin is blended with other natural actives to support hair conditioning and vitality; topical biotin is included as part of a mix designed for fine and thinning hair without giving a dosage in the product information.

What Does Biotin Do?

Biotin helps keep hair strand strength and may support new hair growth in line with cosmetic science context. This aligns with EFSA-style function claims for biotin and its role in maintaining normal hair health, especially when used as part of a balanced hair care routine.

Evidence from the field shows that topical biotin's effects on hair growth aren't robustly proven in large human trials, with some studies suggesting limited or anecdotal outcomes as of now.

This product is not intended to diagnose, treat, cure, or prevent any disease.
