Name Ingredients:
Keratin is a protein that is a key structural component of hair, skin, and nails, providing them with strength and resilience. In hair loss treatments, keratin-based products are used to replenish and strengthen hair fibers, reduce breakage, and improve hair texture and appearance.
Key insights:
- In vitro and in vivo evidence suggests that intradermal injection of keratin can promote hair growth in mice due to the extracellular interaction of keratin with hair-forming cells.
- When applied to damaged hair, K31, a type of human hair keratin, can increase hair diameter by up to 49% and improve the mechanical strength of bleached hair by almost 2-fold.
- There is no clinical evidence showing that keratin can improve hair loss outcomes in humans.
- Our experience tracking members: keratin alone is not enough to improve hair loss outcomes.
