- 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.
- 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.
- 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.

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.”
