The Active Ingredient Is: Keratin (Hydrolyzed)

Keratin is the primary structural protein in hair, and hydrolyzed keratin is enzymatically broken down into smaller amino acids to penetrate the hair shaft.

This form is sourced from natural keratin and processed to improve absorption, supporting hair structure from within.

What Does Keratin Do?

Keratin helps maintain hair strength and elasticity through its role as a major hair protein, with hydrolysed keratin providing amino acids that reinforce hair from within, supporting hydration and shine.

Scientific research suggests that oral keratin hydrolysate can improve hair appearance and related hair health markers after several weeks of use, reflecting a protein replenishment approach for hair durability. Dr. Genovese of a university found improvements in hair appearance with 90 days of keratin hydrolysate.
