Sun & swim can wreck havoc on your hair! We recommend that you always wet your hair with tap water before dunking your head into pool water. Always after swimming- shampoo hair with Bumble & bumble sunday shampoo & condition using quenching masque. This will help prevent a chemical build-up, damage and color changes. To protect hair from the sun, a hat is best, but if you must go without, be sure to add a few drops of Bb. color minded UV protective polish over damp or dry hair.
