Hair smoothing is a treatment designed to reduce frizz, enhance shine, and create sleek, manageable hair. It involves applying a smoothing product (often containing keratin) to the hair, which is then sealed in using heat. This treatment helps to straighten hair, making it smoother, softer, and more manageable for a longer period, typically lasting a few weeks to months. Hair smoothing is ideal for those looking to tame unruly hair, adding a polished look, especially for special occasions like weddings.
