Keratin Hair Enhance
ResVitale
Overview
ResVitale Keratin Hair Enhance contains some ingredients, notably Cynatine HNS keratin and Biotin, that show promise for hair and nail health. The Cynatine HNS is provided at a clinically studied dose (500mg), and the Biotin dose (3000mcg) is higher than typically recommended for general health but aligns with doses used in some brittle nail studies. However, the comprehensive effectiveness of the Resveratrol Polyphenol Complex, which includes Japanese Knotweed Extract and various grape extracts, for hair-specific benefits in this formulation is less clearly established and may be underdosed for broader health benefits beyond anti-oxidation.
The Good
Utilizes Clinically Studied Patented Keratin (Cynatine HNS): Provides a highly bioavailable form of keratin shown to improve hair growth, strength, and nail health for some individuals.
Comprehensive B-Vitamin Complex: Includes B3, B6, Biotin, and Pantothenic Acid, essential for cellular metabolism and overall hair and skin health.
Essential Mineral Support: Contains Zinc and Copper, crucial for enzyme function, immune health, and maintaining healthy hair follicles.
The Bad
High Biotin Dose May Interfere with Lab Tests: The 3000mcg of Biotin can lead to inaccurate results in certain blood tests, potentially causing misdiagnosis.
Resveratrol Complex Efficacy for Hair is Undefined: While it provides antioxidants, the direct impact of the Resveratrol Polyphenol Complex on hair health at this specific dose lacks strong, specific clinical evidence.
Resveratrol Sources May Have Nuances: Japanese Knotweed Extract, a source of resveratrol, has shown potential for increased cardiovascular risk markers at high doses in some studies, although the dose here is likely too low to be a major concern.
