Confused About Surfactants in Hair Care? Read This...
I’ve been back and forth here about the topic of surfactants (Sodium Laureth Sulfates, Sodium Laurel Sulfates, SLS’s) in shampoos. For a while now, I thought that if a shampoo had SLS’s in it, it could not be used on color-treated hair as in, it would not make it last. Period. End of story. How did I come to this conclusion? Probably from a lot of things I read, heard, and the trend of sulfate-free products coming out didn’t help either (and do you remember a few years ago when I discovered that just because a shampoo is sulfate-free doesn’t mean it will make you hair color last any longer? Yup, it’s a confusing world!).
I’ve been lucky enough to come across some major hair people lately and decided to ask them their opinion about SLS’s and if yes, they do kill hair color, or not.
