Hair straightening treatments are cosmetic procedures designed to smooth and straighten curly or wavy hair. These treatments can vary in method, including chemical relaxers, keratin treatments, and thermal straightening. Each technique alters the hair's structure to achieve a sleeker appearance, often lasting several weeks to months. While effective, these treatments can have varying effects on hair health. Some may cause damage or dryness, depending on the ingredients used and the hair's condition. It's essential to consult with a professional stylist to determine the best option for your hair type and desired results.
