What are the best sulfate free shampoo brands?
If you have dry or sensitive scalp, you may benefit from a sulfate free shampoo. Numerous cosmetics and cleaning products contain sulfate in different forms as a foaming agent. Some of these forms are irritants and may even cause contact dermatitis.
Forms of sulfate that are found in shampoo
In order to find a shampoo without sulfate, you should recognize the different forms in which sulfate may appear on the label.
Sodium Laureth Sulfate (SLES) is the major sulfate forms found in shampoos. I’ve looked at 3 different shampoo products in my house hold and they all had Sodium Laureth Sulfate as the second ingredient after water in the ingredient list. Ingredients in the list are ordered in descending order of concentration, thus SLES is the most predominant chemical in those shampoos. Check out the shampoos in your household and see what you find.
Because SLES is a detergent, it is useful for removing oily residues that are not soluble in water it is very common in soaps, shampoos, cosmetics and also cleaning products. This action, however, may cause additional drying of the hair and the scalp skin. Additional sulfate containing detergents that you may find in shampoos are Sodium Lauryl Sulfate (SLS), Ammonium Lauryl Sulfate, Sodium Myreth Sulfate or TEA Laureth Sulfate. All of these are doing the same job as SLES, but some of them are slightly gentler on the skin. Yet, if you have sensitive skin, consider using a sulfate free shampoo. Safety information about most of these common shampoo ingredients can be found at Skin Deep Cosmetics Database.
You may sometimes find shampoo that is marketed as SLS free shampoo. Make sure it does not contain other forms of sulfate instead of SLS or SLES.
Reasons to include sulfates in shampoo, and reasons to avoid them
Why do shampoo brands include sulfate detergents in shampoo?
- Price. These detergents are cheap to produce. Alternative, milder detergents are more expensive to produce and will increase the price of the final product. This is the reason it is difficult to find an inexpensive sulfate free shampoo.
- Function. These detergents are very efficient at cleaning oily and dirty hair.
Foam. Sulfate detergents are excellent lathering reagents. They form a lot of suds, which is what we are used to expect from our shampoos. If you choose to use shampoo that does not contain sulfates, you will most probably get significantly less lathering than what you are used to.
What are the reasons to avoid sulfate detergents?
- Irritation. Sulfate detergents cause skin irritation for some people. Not everyone is sensitive to them, but if your scalp is itch, and you don’t have other scalp problems, using sulfate free shampoo may help.
- Unsafe contaminants. Low levels of 1,4 Dioxane may be found in sulfate containing shampoo. This chemical is a probably carcinogen, and is a by-product of the production process of sulfate detergents. Trace levels of this chemical are found in up to 46% of personal care products tested.
Who should use sulfate free shampoo?

- You have a sensitive skin such as eczema.

- You dye your hair and would like to maintain the color un-faded for a longer time.

Sulfate free shampoo and conditioner are pretty common nowadays. You can find them in the drugstore, grocery store or online. You can also find them in whole food specialty stores or in beauty salons. When looking for sulfate free hair products make sure the label clearly says “sulfate free”. It is also recommended to look at the ingredient list and check that there are no other forms of sulfates.
