Why Sodium Lauryl Sulfate Is Bad For Hair

Why Sodium Lauryl Sulfate Is Bad For Hair

Hey Ladies,

It is very important to know what we are using almost daily on our body.  In one of my articles, I wrote about how bad silicones in shampoos are and today, I am going to tell you why we also should stay away from SLS and SLES.

Why Sodium Laureth Sulfate Is Bad For Hair

Sodium Lauryl Sulfate is also called SLS and it is a cleansing product. It only cleans the surface of anything that will be touched by it. SLS is found in a lot of products such as shampoos or floor cleansers, BUT it can be very harsh on the hair and scalp. You are asking yourself probably, “why would companies put this in shampoos when they know it is a harsh product.”  A simple answer; because it is cheap and creates bubbles/lather.


I used to think that the more bubbles/lather a shampoo makes, the better it is, but that’s wrong. The less bubbles/lather a shampoo makes, the better the shampoo will treat the hair and scalp. I blame this thought on the advertising commercials. The always show a lot of lather and make it look like it is good that the shampoo makes lather.  L’Oreal has a collection of sulfate-free shampoos:

Why SLS is Bad For Scalp and Hair?

It is proven that SLS can cause the hair to thin out permanently which is one of the worst things for us women. Our hair and scalp absorbs everything we put on it and SLS is a harsh chemical that not only will make your hair fall out, but also dry out your hair and scalp. I have heard that when you smell a shampoo that contains SLS and get some of this product in your nose, it will make your nose burn and in some cases even bleed.


A good thing is that you can reverse all the damage that has been done by SLS by switching to a sulfate free (and silicone) free shampoo. Almost immediately, you will notice a difference and of course your hair and scalp will thank you for it.  I will create a list with Sulfate and Silicone Free Shampoos and Conditioners in one of my upcoming articles.

Thank you for your time and reading my article. Take care ladies, xoxo

  1. Thanks so much for this info Sahar. I’ve heard about this and I remember sodium lauryl sulphate from my science classes in school, we were taught it’s detergent, so using that on hair must be horrible. Do you know any other brands that don’t have this?

I’m using Giovanni shampoo and conditioner ( Rs. 495 each) for the past 6 months and I have seen my hairfall completely reduced after using this. Worth for the price. Also better than TBS Rainforest range ( which I have before this).

  18. My Ayurveda doctor had told me ages ago that shampoo that lathers well is bad for hair & made me switch over to Areetha+Shikakai+Amla concoction when I was single & had all the time in World to pamper myself. Now again I have that time but am outta India & dun get these herbal stuff here.. 🙁 But your informative & alarming articles @ haircare are encouraging me to look for herbal shampoos which are available here & having no/minimum of harmful chemicals.. :pigtail:
