Sulfate-Free Shampoo
A shampoo that cleanses with milder surfactants instead of sulfates, popular for colour-treated, dry and curly hair.
What is it?
Sulfate-free shampoo cleanses without the strong sulfate surfactants (such as SLS or SLES) used in many classic shampoos. It uses gentler cleansing agents instead, which usually means less lather and a softer feel after rinsing.
You use it exactly like any other shampoo. Because it foams less, most people apply it to already-wet hair and take a little longer to work it through the scalp.
What does it typically contain?
Sulfate-free shampoos typically contain milder surfactants such as cocamidopropyl betaine, coco-glucoside or sodium cocoyl isethionate, plus conditioning agents, humectants like glycerin and sometimes plant oils. Exact formulas differ from brand to brand, and sulfate-free does not automatically mean silicone-free or vegan.
Formulas differ from brand to brand. Always check the ingredient list on the product you are buying, especially if you have known sensitivities.

Benefits
- Cleanses more gently, so hair often feels less stripped
- A common choice for colour-treated hair, where harsh cleansing can speed up fading
- Usually suits dry, curly and coily hair that loses moisture easily
- Often more comfortable for people who find regular shampoo drying
Drawbacks
- Less lather, which can feel like it is not cleaning properly
- May struggle with heavy styling product or oil buildup
- Often needs two washes on very oily scalps
- Not automatically milder in every formula — the rest of the ingredient list still matters
Best for
- Colour-treated or bleached hair
- Dry, curly or coily hair
- Anyone whose scalp and lengths feel tight after washing
- People building a gentler, low-stripping routine
When to choose something else
- If you use a lot of wax, gel or dry shampoo, a clarifying shampoo is usually the better pick, at least occasionally.
- If your main concern is dryness rather than cleansing strength, a hydrating shampoo is usually the better pick.
- If your scalp flakes or itches, a scalp shampoo is usually the better pick.
- If your hair is damaged and fragile, a repair shampoo is usually the better pick.
Frequently asked questions
Is sulfate-free shampoo better for everyone?
No. It suits dry, curly and colour-treated hair especially well, but oily scalps and heavy styling routines often do better with a regular or occasional clarifying shampoo.
Why does sulfate-free shampoo barely foam?
Lather comes mostly from sulfates. Milder surfactants clean with less foam, so the amount of bubbles says little about how clean your hair gets.
Does sulfate-free shampoo make colour last longer?
Gentler cleansing can slow colour fading, though water temperature, sun exposure and how often you wash matter just as much.
