Is sulfate-free shampoo best for colored hair?

From the iciest platinum blonde to the deepest shade of auburn, once you’ve made the effort to have your hair professionally color-treated at the salon, that’s an investment you’ll want to protect for as long as possible in between appointments. You may have heard you should stay away from sulfates in your shampoo if you have colored hair, but does the shampoo you use to wash color-treated hair really make a difference?

What are sulfates?

Sulfates are an active ingredient in shampoo that acts as a cleaning agent. They give shampoos their foamy, sudsy texture and they function by cleansing away dirt, oil and built-up styling products on your scalp and in your hair. Sodium laurel sulfate (SLS) is one sulfate you’ll often see included in formulas for shampoos and other hair and skin care products.

The hairstyling industry has continued to recommend sulfate-free shampoos for color-treated hair because sulfates cleanse away the oil and dirt in your hair, they can also fade your color over time. “When you use a shampoo with sulfates such as SLS, your hair may feel clean, but sulfates may strip away too much moisture from your hair and scalp,” says board-certified dermatologist and LovelySkin CEO Dr. Joel Schlessinger. “Hair that’s lacking moisture is more prone to breakage as well, which is why I do prefer products to be SLS-free.”
