Step-by-Step Guide: How Keratin Treatment Works on Hair explains the process of transforming frizzy, unmanageable hair into smooth, shiny, and healthy-looking locks. First, hair is washed thoroughly to remove dirt, oil, and residue. Then, the keratin solution is applied evenly and left to penetrate the hair shaft. After application, hair is blow-dried and sealed with a flat iron to lock in the keratin. The treatment strengthens hair, reduces frizz, and enhances shine. Regular care after treatment maintains results, making hair more manageable and vibrant over time.
