Why this formula

Hair, Skin & Nails in context

Hair, Skin and Nails Strips deliver biotin, folate and vitamin D3 in a dissolvable orange strip. The product is intended to support normal nutrient-dependent processes involved in hair, skin, nail and cellular health.

Biotin is essential, but cosmetic benefit from supplementation is best established when deficiency or a relevant disorder is present. Folate supports cell formation, and vitamin D participates in skin, immune and calcium-regulation pathways.

The 5,000 mcg biotin dose is high enough to interfere with some laboratory assays. Customers should tell clinicians and laboratories that they use a high-biotin supplement.

Dermatology review

Micronutrients and hair loss

A large review links iron, vitamin D and biotin deficiencies with hair changes while warning that indiscriminate supplementation lacks evidence.

Case-control study

Vitamin D and alopecia areata

A case-control study found lower vitamin D levels in alopecia areata and an association with disease severity, which does not prove supplementation treats hair loss.

Evidence note

High-dose biotin can distort thyroid, troponin, hormone and other laboratory tests. Benefit for cosmetic growth in people without deficiency is not established.
