SLS Free Shampoo

What is SLS and why avoid it?

Sodium lauryl sulfate is a surfactant used in many shampoos to create lather and lift oil from hair. It is effective and inexpensive, which is why it is so common. Some people find it strips more natural oil than they would like, particularly if they have dry, curly or colour-treated hair, and prefer formulas that clean using milder surfactants instead.

Does SLS-free shampoo still lather?

Less dramatically, yes. Alternative surfactants produce a softer, lower foam, which many people initially read as the product not working. It is not a measure of how clean your hair is getting. You may need slightly more product for the first few washes while your scalp adjusts to a gentler formula.

Is SLS-free better for coloured hair?

Many people colouring at home or in salon choose SLS-free formulas because harsher surfactants can lift colour molecules more quickly with each wash. Combining an SLS-free shampoo with cooler water and washing less frequently generally helps colour hold longer.

What is the difference between SLS-free and sulfate-free?

SLS-free means that one specific ingredient has been excluded. Sulfate-free is broader and excludes related compounds such as sodium laureth sulfate and ammonium lauryl sulfate. If you are avoiding sulfates generally, check the full ingredient list rather than relying on front-of-pack wording alone.

How do I build a routine around it?

Pair with a conditioner suited to your hair type and concern. Browse the full hair care range, or the hair essentials section for shampoos, conditioners and treatments. If you colour at home, the hair colour range sits naturally alongside a gentler wash routine.
