You are part of the green and clean revolution if you are actively looking for the best sulfate-free shampoo bar. This serves two important purposes: one, with a shampoo bar, you don’t generate or consume plastic bottles, and two, you ditch one of the most harmful preservatives that go into beauty products. Sulfates are not only bad for the environment as it finds their way to the water bodies, but also disrupts hormone production in women.

Look for SLS (sodium lauryl sulfate) and SLES (sodium laureth sulfate) when going through the ingredients listed on the labels of haircare products and keep them back on the shelf. This is one way to go about choosing sulfate-free shampoos. Alternatively, you can explore our list of the 13 top sulfate-free shampoos available as bars on the market, right here!

With a wide variety of shampoo bars available in the market choosing the right one may seem like a daunting task. Worry no more! The following pointers will help you choose the best shampoo bar for yourself.

Types Of Shampoo Bars

There are 3 main types of shampoo bars

  1. Cold-pressed: This process of making soaps and shampoo bars is followed by many major companies manufacturing SLS-free shampoo bars. Cold-pressed bars typically contain nourishing oils that condition your hair but may cause oil build-up. Thus, users may require to rinse their hair with a clarifying agent post-use.
  1. Solid surfactant: These soaps lather the best due to the presence of SLS but are avoided by a vast majority of people due to irritation.
  1. Glycerin-based: These soaps contain natural glycerin, which has a lower pH level to keep hair and scalp moisture-balanced.
  • Shampoo bars are easy to use and are long-lasting as compared to shampoos. Shampoos are made with almost 80% water and are therefore easily perishable, while shampoo bars are more concentrated and will last you for many days.
  • Shampoo bars are travel-friendly as well as eco-friendly as they eliminate the use of bulky plastic bottles.
  • Most shampoo bars do not contain any artificial ingredients such as preservatives and detergents that affect the natural pH value of your hair.

Laura Dale, licensed cosmetologist, says, “Shampoo bars are a great option for those looking to reduce their plastic waste and minimize their carbon footprint. My tips for using shampoo bars are to make sure to thoroughly rinse your hair to prevent any residue that could weigh it down, and to look for bars that contain nourishing ingredients like shea butter and argan oil to moisturize the hair and scalp.”

How To Use Sulfate-Free Shampoo Bars

The following is a step by step guide to using shampoo bars:

Step 1: Wet your hair well and also wet the shampoo bar.
Step 2: Rub the shampoo bar on your scalp in the direction of your hair growth.
Step 3: Lather it using your fingers in a circular motion.
Step 4: Distribute the lather from the roots to the tips of your hair.
Step 5: Wash out the soap from your hair and repeat the entire process if required.
Step 6: Towel dry your hair without using any hair dryers.
Step 7: Apply hair serum and let your hair dry naturally.
