Hydrolyzed keratin is a powerful protein ingredient derived from natural sources such as wool, feathers, or hair. It is enzymatically or chemically broken down into smaller peptides, making it easier for the body or skin to absorb. But what is hydrolyzed keratin used for, and why is it gaining attention across multiple industries?

1. Hair Care

Hydrolyzed keratin is widely used in shampoos, conditioners, and hair masks to:

· Repair damaged hair fibers

· Strengthen brittle or chemically treated hair

· Improve elasticity and reduce breakage

· Smooth frizz and enhance shine

It penetrates the hair shaft, replenishing lost protein and restoring structure from within.

2. Skin Care

In skin care formulations, hydrolyzed keratin:

· Provides a protective barrier on the skin

· Enhances moisture retention

· Supports skin elasticity and texture

Its small peptide structure helps nourish the skin deeply without irritation.

3. Nutritional Supplements

Hydrolyzed keratin is also used in nutricosmetics and dietary supplements for:

· Supporting healthy hair, skin, and nails

· Promoting collagen and keratin production internally

It is especially popular in beauty-from-within products.

Conclusion

Hydrolyzed keratin is a multifunctional ingredient with proven benefits for hair, skin, and overall beauty support. Its bioavailability and effectiveness make it a valuable component in cosmetics, personal care, and health supplements.
