So how does a sulfate-free shampoo cleanse hair?
Although it might seem quite obvious that “no sulfate shampoo” contains no sulfates, it’s important to understand how it differs to ‘normal’ shampoos. If sulfates provided the emulsifying, cleaning ability in shampoos, you’re probably wondering what is used instead to cleanse the hair. This pretty much depends on the product. Some sulfate-free shampoos contain no lathering agents at all. And this is why you won’t get much or any foam out of them.
But despite how this might make us feel (seeing as we’re so used to lather = washing), this doesn’t mean they aren’t cleansing the hair. Despite how it may feel initially on your scalp, no-lather shampoos also have the ability to remove dirt and grime. However, they tend to leave a little more of the hair’s natural oils behind. This can be great for naturally dry hair that finds shampoos can strip too much moisture from strands. Coloured hair also tends to respond well to sulfate free shampoo. In fact, if over-used it can strip the hair of its colour just like a lathering shampoo.
So it’s safe to say that although the ‘cleaning’ ability remains the same, our ability to accept a lather-free wash may take some getting used to!
