Keratin—the protein that helps strengthen hair to prevent breakage, heat damage, and frizz—is vitally important for maintaining strong and healthy hair.
First, you'll get a really good, clarifying shampoo to get any product or buildup that may be on your hair completely out. Then, section by section the keratin product, which disrupts your natural curl pattern and causes it to straighten, is applied and combed through, then blow-dried.After you're dried, your hair gets straightened with heat. "The straightening part is actually the part where the keratin locks into the hair," she says, adding that she would adjust heat and number of times she passes each section depending on what look her client wants: higher heat and seven to 10 iron passes for stick-straight; lower heat and three to five times to keep some wave.After your hair is straightened, you rinse your hair one more time but don't shampoo it, then another locking product is applied to ensure it stays for the full three months. The whole process takes about two hours.
