A warm mask will work better than a cold one, but you don't want hot!
Hair masks should be left on for a minimum of 15-30 minutes. The longer you leave it on, the more it can work
Sometimes hair is too damaged to repair.
Long, or thick hair may require a double batch.
Avoid using heat styling (blow dryer or straightening irons) for at least 24 hours after application.
Don't use shampoo or conditioner with SLS or SLSA after the mask, they will strip out all of the good work you just did. (Try one of ourย Sulfate-Free Shampoo Bars)
