The hair cuticle is the outer coating of the hair, and the hair cuticle also gives the look of the hair. If you have frizzy hair, flyaway hair, usually the hair cuticle is damaged. Therefore, you want something that's going to smooth it out, make it look shiny. That's where hair products like hair serums, silicone products, and oils come into play. They coat the outer shaft of the hair, and they give that beautiful, shiny texture.
