Real Talk — How Bad Are Sulfates for Your Hair?
If you’ve ever taken a stroll down the hair care aisle at the store, you may have noticed that there’s a huge market for shampoos labeled “sulfate-free.” Oftentimes, we automatically assume that this means the product is somehow cleaner and better for our hair. But, do any of us know what sulfates actually are? Are they really the hair-damaging monster that we’re led to believe?
What are sulfates?
Sulfates are a type of chemical that can be used as a cleaning or foaming agent. The sulfates are a large part of why our shampoo suds up when we mix it with water. Usually, the sulfates that are used in hair products are sodium lauryl sulfate, ammonium lauryl sulfate and sodium laureth sulfate.
Sulfates are used in shampoo not only for their foaming abilities, but also because it helps remove dirt and oil from the hair. Some consider sulfates problematic because they do such a good job of stripping the hair — almost too good. Some people find that shampoo-containing sulfates completely strips their hair of its natural oils and leaves it super dry.
Who could benefit from going sulfate-free?
People with color-treated hair: If your hair has been dyed, it may be best to avoid shampoos containing sulfates. Sulfates can strip the color from the hair and cause it to fade quickly.
People with sensitive skin: Those with sensitive skin may find that the sulfates irritate their skin and cause their scalp to become red, dry and itchy.
People with naturally dry hair: If your hair tends to be on the dryer side, it may be in your best interest to skip the sulfates and opt for a shampoo that is ultra-hydrating. The sulfates in shampoo may be what’s causing your hair to become even dryer as its natural oils get washed away.
Who could sulfates be good for?
Anyone whose hair gets dirty throughout the day: Sulfates are really excellent at cleaning hair and getting rid of all the dirt and debris. If you work in an environment that causes you to excessively sweat or get dirty, a shampoo containing sulfates may be what you need to properly clean your hair.
People with naturally oily hair: If your hair tends to be naturally greasy, a shampoo using sulfates could help wash away the accumulated oil.
People with dandruff: Excess oil can make a dandruff problem worse, so a shampoo with sulfates could help with this flakey problem.
There’s a misconception that sulfates are terrible for your hair and could even cause cancer. However, there is no scientific evidence that shows a link between sulfates and cancer. The truth about sulfates is that they’re not for everyone, but some people could really benefit from them. At the end of the day, we all have different hair types, and what works for one person may not work for another. Don’t be too quick to judge sulfate-containing shampoos!
