Why Sulfates Are Not Actually Damaging Your Hair

Now that we've explored the idea that sulfates are not necessarily dangerous, let's look at how they affect your hair. "Sulfates have not been determined to strip hair color," Wilkerson said. "There's no foundation for that in terms of data."

As for hair damage, Wilkerson shared an interesting study with us that proved their safety. The study compared a product that contained sulfates to different types of sulfate-free formulas. It showed the hair loss over several cycles, washes, and hair brushing. Though each was treated the same, the product containing the sulfates left hair the healthiest.
