Hair treated with keratin protein, otherwise known as the “Brazilian blowout,” has exploded into popularity. But the treatment requires care on your part to keep hair looking smooth and straight.
Avoid getting your hair wet for three days after the treatment. This means no washing, swimming and sweating as well as staying out of the rain. Water and moisture can wash away some of the protein treatment, leaving marks in the hair, according to Tracy Kollmer with M&M International Inc., a major distributor of keratin protein treatment products.
Leave your hair down and straight for the first few days after your treatment. The keratin is still malleable, so if you put your hair in a ponytail or use a hair clip, it can leave dents in the hair. If you want to tie your hair up, wait until the keratin has been on the hair for at least three days, and then use a soft hair tie for short periods of time.
Purchase a shampoo and conditioning set that is sodium lauryl sulfate or sodium laureth sulfate-free. Both forms of SLS are powerful detergents that strip hair of its natural oils. When used with a keratin protein treatment, SLS shampoos can remove the protein and your treatment will not last as long, notes StraightenMyHair.com. Non-SLS shampoos can be found at health food and organic stores.
