There are a few reasons you might want to avoid sulfates in shampoos. While sulfates can help cleanse your hair, they might do their job a little too well and can pull too much natural oil from your hair and skin. This can cause your hair to feel dry, frizzy, or brittle.
Sulfates can also strip and dull color-treated hair and diminish the smoothing effects of keratin treatments. Sulfates aren't necessarily bad for all hair types, but if you already have dry, overly processed, or damaged hair, you might want to avoid them.
However, they can be harsh on the hair and scalp, which is why many shampoos with sulfate also contain ingredients designed to help hydrate and smooth the hair (such as hyaluronic acid). Still, swapping to a sulfate-free shampoo might be a good option if your hair is dry, brittle, or prone to breakage.

Key Sulfate-Free Surfactants
One of the main benefits of a sulfate-free shampoo is that it's less likely to strip the hair of its natural oils. Sulfates can sometimes make hair dry and prone to frizz. Sulfate-free shampoos use gentle cleansing agents that preserve the moisture balance of your hair and scalp.
Sulfate damage typically appears in the form of hairline cracks called “etching,” or white, powdery stains referred to as “efflorescence.” The first places to look is on the flatwork (walkways and sidewalks), along the exterior foundation, or the block wall.
In shampoos, sulfates create tension between the product washing your hair and the dirt you're trying to clean: They latch on to both the water and dirt, dragging out oil and impurities from your hair. This process creates the foamy lather that many consider the hallmark of a good shampoo.
