Sulphate-free shampoo is all the rage lately, but does it make sense to limit yourself to fewer products? Before you decide, here are the pros and cons of sulphate-free shampoos for colour-treated hair.
While sulphate-free products can be great for certain hair types, they're not for everyone. Here’s what you need to know about choosing the right shampoo for colour-treated hair.
What Are Sulphates?
Sulphates are a type of detergent. Responsible for the cleansing power of laundry soap and liquid skin cleansers, sulphates cut through dirt and oil.
If you grab your nearest bottle of body wash right now, you’ll see it probably contains sodium lauryl sulphate or ammonium lauryl sulphate. Just as sulphates remove grease from a dirty pan, they remove oil from your scalp.
If Sulphates Work, Why Avoid them?
For many people, sulphates just aren’t necessary. A small amount of oil in your hair is a good thing. Natural sebum makes your hair feel silky and smooth. When you wash oil away, your hair is stripped and feels drier.
Without sulphates, shampoos don’t froth up. Additionally, sulphate-free shampoo tends to be very runny, so other thickening ingredients must be added. Sometimes, these alternative products are great for your hair; sometimes, they aren’t so great. 'Sulphate-free' isn’t a guarantee of quality or purity.
Is Sulphate-Free Shampoo Better for Colour-Treated Hair?
Shampoo with sulphates is great for removing product build-up and oil. It can, however, dry out your hair. If your hair is already dry from colouring, sulphates can cause serious long-term damage. Generally speaking, anyone with hair that tends to be dry could benefit from ditching sulphates.

Who Shouldn’t Use Sulphate-Free Shampoo?
If you have fine or thin hair that tends to be oily, sulphate-free shampoo will likely turn your hair into a mess. If your locks start to feel greasy within 24 hours of washing, you need to stick to a shampoo with stronger detergents. Consider Wella SP Delicate Volume, which does contain sulphates but cleanses gently whilst adding body.
Do you work out regularly? Good for you! But whereas exercising might be great for your body, it’ll leave your hair oily. You’ll more than likely need a light dose of sulphates after every sweat session. Go for O&M Original Detox Shampoo to keep your hair clean and healthy.
