Keratin is one of the most talked about hair care ingredients, yet it is often misunderstood. Many people associate keratin with chemical straightening, but keratin itself is simply a protein your hair already has. When used correctly, it helps strengthen, smooth, and protect the hair without changing its natural texture.
What keratin does is reinforce weakened strands. Heat styling, coloring, extensions, and environmental stress can slowly break down the hair’s structure. Keratin based products help fill in those weakened areas, improving strength, elasticity, and shine. Hair that lacks protein often feels frizzy, rough, or limp, and struggles to stay smooth. In these cases, keratin can help restore balance and manageability.

What keratin does not do is permanently straighten your hair. Mirta de Perales Keratin products are not a straightening treatment. They are a maintenance line designed to cleanse, condition, and repair hair while supporting its natural pattern. This makes them ideal after a keratin service, for color treated hair, or for anyone who regularly uses heat tools or wears extensions.
Mirta de Perales Keratin Line is sodium sulfate free and formulated with keratin protein to help protect hair from heat, styling, and environmental damage. With consistent use, hair feels softer, looks shinier, and becomes easier to style with less frizz and breakage. Think your hair might benefit from keratin support?
