- You don’t rinse your hair enough and use too much shampoo.
Rinsing your hair thoroughly for at least a minute before applying shampoo helps to remove any residue from the last hair care product you used. Letting your hair get completely wet before applying shampoo is an essential step to effectively wash it. If your hair is wet from top to bottom, the shampoo will lather better and spread more evenly. It will also help you use less shampoo when washing your hair.
