A keratin treatment is primarily designed to smooth and straighten the hair. This technique works by infusing the hair with keratin, which is a natural protein found in hair, skin, and nails. When applied, the treatment adheres to the hair strands, filling in gaps and creating a protective layer that can help reduce frizz while making the hair easier to manage.

The process effectively alters the hair's texture, aiming for a sleek, shiny, and straightened appearance that can last for several weeks or even months, depending on the specific treatment and hair type. This is particularly beneficial for those with curly, wavy, or frizzy hair who desire a smoother look without the need for daily heat styling.

While reducing frizz and adding shine is a part of the overall effect of the treatment, its primary function is more aligned with providing smoothness and straightness, making it a popular choice for individuals looking to achieve a polished hairstyle.
