What should I do after keratin treatment?

It's important that your hair stays completely straight for the first 3 days after a keratin treatment, so avoid hats, sleep caps, scrunchies, and hair wraps. When you sleep, leave your hair down and use a silk or satin pillowcase to reduce creases and frizz. Try to sleep flat on your back with your hair straight. Touch and brush your hair as little as possible during the first 3 days, and wash your hair 2-3 times a week after the 4th day so the treatment lasts.
