Purchasing sulfate-free and alcohol-free products is a necessity as they are imperative to maintain the health of your extensions. These ingredients strip the hair of its natural oils and will affect their integrity. This, in turn, makes the hair drier and more prone to tangling or matting. Be sure to check the ingredient listing and ensure you don’t see the words: SLS, Sodium Lauryl Sulfate, Sodium Laureth Sulfate, Alcohol Denat, Ethanol, SD Alcohol 40, Propanol, Isopropyl, and Propyl.
