The Bumble & bumble Quenching Shampoo is a supersaturated formula for really thirsty hair. When you mistreat your locks with heat & rough styling, it can result in chronic dryness. This ultra mild cleanser is the first step in putting some much-needed moisture back in, with a wealth of gloss-enhancing, dryness-busting & softness-boosting ingredients. Wet hair, lather up & rinse away thoroughly. Follow with the Bumble & bumble Quenching Conditioner or Quenching Masque for extra replenishment.
