Keratin oil is a beauty product specifically formulated for hair care, containing keratin, a protein naturally found in hair, skin, and nails.
Derived from sources like wool, feathers, or plant extracts, keratin oil is highly valued for its ability to restore and strengthen damaged hair, making it smoother, shinier, and more manageable. In the 1950s, the discovery of keratin's hair-repairing properties revolutionized the hair care industry, paving the way for the development of keratin-based products.
