What kind of products should I use after getting the treatment?
Steer clear of products that contain sulfates, as well as shampoos and conditioners with sodium chloride. These elements cause the treatment to wear off faster, leaving you with a two to three month wear time, as opposed to the typical four to six months. Swap out your products for more gentle options, like
Jonathan’s Smooth No-Frizz Shampoo and Conditioner ($18 each;
