Chemical hair treatment involves the use of various chemicals to alter the structure and appearance of hair. Common types include permanents, which create curls or waves, and relaxers, which straighten curly hair. These treatments can change the hair's texture, making it more manageable or styled according to personal preference. While chemical hair treatments can enhance beauty, they may also cause damage if not applied correctly. It's essential to follow proper application techniques and aftercare to maintain hair health. Consulting a professional stylist can help ensure the best results and minimize potential risks associated with chemical treatments.
