Time Frame

Considerations

• Use Bumble and Bumble Deeep Treatment if your hair has been sun-damaged as well. Spend the recommended time under the dryer after applying the conditioner. Or, if you're washing your hair at home and don't have a dryer, leave the product on your hair and wrap your hair in a warm towel for the recommended 20 minutes.
