What happens if I use a product with sulfates on my treated hair?
If you accidentally grab the wrong product in the shower, don’t fret. Although sulfates and sodium chloride cause the treatment to wear off, you can replenish the keratin in your hair by loading up on products rich in the protein. “We recommend using Keratin Complex's Intense Rx ($61; keratincomplex.com),” Raubeson said. “This reinvigorates the hair with keratin and emollients, and revitalizes hair during thermal styling.” Another option we love: Sally Hershberger’s Super Keratin Spray ($13; ulta.com), which can be used to soften damp and dry strands alike.
