Look for formulas with nourishing ingredients like argan oil, keratin proteins, or coconut oil to reinforce the treatment’s benefits. Avoid anything with harsh sulfates or sodium chloride, as these can break down the keratin bonds prematurely. A good shampoo should cleanse without weighing hair down, leaving it soft and easy to style. Stick to products specifically labeled for keratin-treated hair for the best results.
