What Happens If I Leave Purple Shampoo On My Hair For 2 Hours?
Leaving purple shampoo on your hair for 2 hours may result in overtoning or a dryness in your hair. This can happen because the shampoo may have stripped away too much of your hair’s natural oils. It can leave your hair feeling brittle, dry and may cause some breakage. It is advisable to follow the instructions on the label carefully while using purple shampoo and avoid leaving it on for too long.
