DIAGNOSIS: PRODUCT BUILD UP SYNDROME
If your hair just doesn’t feel clean enough, even after double shampoos, youÂ may be a victim of product buildup….a common affliction.Â Dull, limp or oily hair requires special attention. You need to wash away all the residue from hard water, smoke, chlorine, salt, gels, mousses, serums without stripping essential moisture and oils.
Clarifying shampoos tend to beÂ higher in pH since they are based on acetic acid, so they can also dryÂ out your hair and scalp. You can use clarifying shampoos once a week to manage product buildup and prevent oily roots. Use sparingly on dry or color treated hair – once every two weeks is probably enough
