As a physician I get asked many questions every day. Most questions are pretty standard. Is eating this really that bad? Should I cut out sugar? etc. However, every now and then I get a question I haven’t heard before. A question that gets me thinking. During my recent travels, I was asked if it “is healthy to use salt free shampoo?”. Salt free shampoo?! Until that very moment I have never heard of such a thing. They definitely didn’t cover Salt free shampoo in Medical School.
Salt, or Sodium Sulfate, is added to shampoo to occupy space. That means it takes up room and adds consistency to the shampoo. Sodium sulfate is also a surfactant and creates the lather you get while washing the hair. By bubbling and lathering it does the job of basically a soap – it cleans or gives a fresh feeling. Unfortunately, by doing so, it breaks the hair, striping away Keratin (a protein used to build the hair’s structure) and leaving the hair freeze and dry. This might pose a problem for hair that is dry, dyed or hair receiving keratin treatment.
Turns out that there are shampoos which contain no sulfate and therefore help keep moisture and color to the hair. In fact, some salon which specialize in keratin treatment requires no sulfate shampoo after treatment. Sulfate free shampoo are available and usually more expensive then regular shampoo. A no sulfate shampoo still clean your hair with washing even though it does not foam up,
So is salt free shampoo healthy? The conclusion I arrived is that it depends on your type of hair. It’s worth trying it if you can find it & afford it. For some individuals that are sensitive or allergic to salt, this is a must use. For others it can be an optional thing to try. Salt free hair product might also be right for you if you want to try something new and/or with less chemicals. Who knows, it might make your hair even more beautiful. Definitely worth a try.
What do you think? Do you use a Salt Free shampoo?
