We know… you read on a blog that sodium coco sulfate is actually the same as SLS and is a harsh detergent that you shouldn't use in your hair. But then another blog you read said it was safe, and even Curly Girl approved. It can be confusing can’t it? So who do you listen to?
Friend or enemy?
At Nourished, we rely on science, not speculation. With three science degrees between us, we dive deep into the research and consult global experts to ensure we’re giving you the very best in clean hair and skin care.
“First of all, people who say that SCS can’t be natural need to do more research,” says Thomas De Waal, Organic Chemist and founder of Rebel Nature, a natural cosmetic formulation laboratory.
Sodium coco sulfate, derived from coconut oil fatty acids, is a palm-oil-free surfactant often used in natural hair and skin care. It offers a gentle, effective alternative to the harsher sulfates like SLS, sodium laureth sulfate (SLES), and ammonium laureth sulfate (ALS).
+ It creates a naturally beautiful foam.
+ It gently but effectively cleanses hair and scalp.
+ It’s 100% biobased, derived from renewable coconut oil.
Let's go through this together:
1. Foaming Capability
One of the biggest frustrations with sulfate-free shampoos is the lack of lather. No foam often means no thorough cleanse, leaving hair dull, flat, and even a little grimy.
That’s where SCS shines. In our Hair Wash, it creates a rich, fluffy lather that helps cleanse your scalp and hair effectively—without stripping away the natural oils that keep your hair healthy. It’s even gentle enough to use in baby shampoos.
2. Gentle, Effective Cleansing
Healthy hair and scalp need regular cleansing to remove dirt, sweat, pollution, product residue, and excess sebum. If left unchecked, these impurities can leave behind alkaline residue, forming calcium salts that dull and tangle hair. Worse, buildup can block follicles, potentially harming hair growth and quality.
The challenge? Striking the right balance between cleansing and maintaining the natural oils that give hair its shine, volume, and (if you’re lucky) curls.
We’ve formulated our Daily Hair Wash to do exactly that. The SCS we use is a mild surfactant that effectively clears away impurities while protecting the delicate oil balance of your scalp and hair.
“It’s just one part of the final formulation,” explains De Waal. “It adds that extra touch of gentle cleansing. Combined with other carefully chosen ingredients, it helps create the perfect balance to cleanse hair without causing damage. For the best results, layering is key—start with Hair Wash, follow with the Daily Conditioner, and finish with Hair + Beard Oil.” (stay tuned for these products, coming soon!)
3. Renewable Source, Responsible Choice
De Waal states that “Whilst it is true that sodium coco sulfate can be made chemically, ours isn’t. We source SCS that is derived from the renewable source of natural fatty acids of Coconut Oil, not petroleum or palm oil. As such it is a pure ingredient without the common harsher sulfate by-products of a mixed ingredient like SLS. Impure or mixed SCS is cheaper and more commonly used in hair care & cosmetic products.”
