A post from a few years ago but so relevant today!
These sulfates are all primary detergents that make shampoos, body washes and other cleansers clean and foam. Without these ingredients cleansing products wouldn’t work nearly as well as they do. The Beauty Brains
The number one purpose of using a shampoo is to clean the hair. That means stripping the oils that can trap dirt and pollutants. They also remove the build up of products we apply to the hair in between washing's. Now, I am one that has to see a lather of shampoo in my hair. I only use it once, none of that repeat garbage because one use of the shampoo is enough for me. I'm not putting a ton of gunk in my hair to require shampooing twice.
Now I understand that some find these sulfates irritating to their hair and/or skin and by all means they need to stay away from them. There are some who find them too drying and there are ways around that as well. You can dilute the shampoo to weaken it's potency or you can do like me and apply an oil to your hair prior to shampooing to keep the shampoo from stripping all the oils out.
I also use a really good sulfate-free shampoo that gets my hair squeaky clean, Kinky Curly Come Clean Shampoo. I get the lather I have the need to see and it works quite well. When I'm using some not so Natural products it works really well but when I'm using the rest of the Kinky Curly Line I don't need a lot of it. Hence, doing a pre-oil poo.
But just like The Natural Haven suggests:
I think that people need to make their own decisions and learn to read ingredient labels. In my personal case, I know that from testing, my scalp and skin prefers SLES as a surfactant for normal washing and really dislikes a different sulfate surfactant - ALS. I have tried two sulfate free shampoos and I found them expensive and wasteful because I required a lot of the product to get my scalp clean. Other people like sulfate free shampoos, some people totally avoid shampoo, some people avoid SLES, ALES etc because of cancer concerns.........make your own decision to suit what your scalp and mind prefer.
You have to do what works for you and that may require trying a sulfate shampoo, a non-sulfate or even just not using shampoo at all and just doing the co-washing. What works for some or even many may not work for you and Sulfates have a purpose that many find suitable. I didn't go looking for a sulfate-free shampoo when I found KC Come Clean and even though it's sulfate-free I STILL apply oil to my hair prior to shampooing. THAT works for Sabrina. It may not work for others but the bottom-line is get to know your hair and what it likes. Sulfate or not.
