Keratin is a family of fibrous structural proteins, and the key structural material that makes up hair, nails, and the outer layer of your skin. Keratin makes hair strong and lustrous; but the protein is weaker in curly and textured hair, which results in dryness and frizz.
A keratin treatment is nothing but a chemical process in which salon professionals coat hair strands with the protein to make them smooth and shiny. While there are different types of keratin treatments, on a basic level, all of them involve diving into the hair follicle and injecting the porous areas with keratin to make hair healthier.
