Keratin treatment and hair straightening are two popular hair treatments, each with its own unique purpose. Keratin treatment primarily focuses on improving hair health and reducing frizz by infusing the hair with a protein called keratin, which helps to strengthen and smooth the hair shaft. It results in smoother, more manageable hair with reduced frizz and enhanced shine. On the other hand, hair straightening aims to alter the hair's natural structure to achieve a straightened appearance using chemicals or heat tools. While both treatments can lead to straighter hair, keratin treatment prioritizes overall hair health and manageability, while hair straightening focuses solely on altering the hair's texture.
