Chemical hair services involve the use of various chemical products to alter the structure and appearance of hair. Common services include permanents, which create curls or waves, and relaxers, which straighten curly hair. These treatments can enhance hair texture and manageability, but they require careful application to avoid damage. Before undergoing chemical hair services, it is essential to consult with a professional stylist. They can assess hair type and condition, recommend suitable products, and provide aftercare instructions. Proper maintenance, including using sulfate-free shampoos and deep conditioning treatments, helps preserve the results and keep hair healthy.
