Q&A for How to Sleep After a Keratin Treatment

A keratin treatment is a procedure that infuses keratin into the porous parts of the hair strand to add shine and smoothness while reducing frizz and wave. The hair is first washed and clarified to remove any impurities. Afterwards, the keratin solution is applied to the hair in sections, thoroughly dried, then ironed into the hair to bond and seal. On average, the entire process takes about 90 minutes.

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.

Wait until at least the 4th day after your treatment to shower and use a sulfate-free and chlorine-free shampoo so you don't wash the keratin out. About 3 days after your treatment, use coconut oil or argan oil to add moisture to your hair if it gets frizzy. Shower 2-3 times a week at the most and avoid swimming in chlorinated water so the treatment lasts longer.

It's very important that you allow your hair to stay completely straight for at least the first 3 days after a keratin treatment. After it's had time to properly set in your hair, the keratin will make your hair smooth, shiny, and free of frizziness.
