The best shampoo for permed hair is alkaline-free and contains deep moisturizing ingredients. There are multiple brands from which to choose, and some top brands include Tresemmé Flawless Curls, Bumble and Bumble Curl Conscious shampoo and Aveda's Be Curly shampoo.
Alkaline shampoos are extremely harsh on newly-permed hair. These shampoos can remove the curls if used within a week or two after a permanent wave. Moisturizing shampoos are more acidic than alkaline, and they allow for continual moisture and nourishment for chemically treated hair. Additional tips for washing and caring for permed hair include gentle scrubbing and air drying as these techniques allow the curls to settle in over time.
