For Residue-Ridden Hair

"Nothing eats through product buildup like baking soda," Cox says. Sodium bicarbonate essentially breaks down anything acidic.

To Use: Mix 1 to 2 Tbsp baking soda with small amounts of water until a thick paste forms. Massage into damp hair and let sit for 15 minutes. Rinse with water, then shampoo hair. Treatment can be applied every two weeks.
