I''m not expert i'm just telling you what i read:
1. After you wash your hair, give it a final rinse with carbonated or sparkling water. The reason carbonated or sparkling water reduces frizz is because of it’s low pH level.
2. Beer is another great rinse option, and ranks third on our list of unconventional no-frizz tips. Beer replenishes moisture in your hair. Dark beers often provide the most nutrients and moisture. When doing the rinse, simply coat your hair with them and let it sit for a few minutes. When ready, rinse your hair with cold water—which will also help get rid of the smell.
