The best sulphate-free shampoos for curly hair cleanse gently without stripping the natural oils curls need, which helps reduce the dryness and frizz that harsh sulphates cause. Curly and coily hair is naturally drier, so a gentler wash makes a real difference. Our top UK picks below — all checked against the Curldrop Standard — are led by the SheaMoisture Manuka Honey & Mafura Oil Shampoo for very dry hair and Camille Rose Curl Love for a gentle everyday wash.
Why choose a sulphate-free shampoo for curly hair?
Sulphates (like SLS and SLES) are the strong detergents that make shampoo lather. They're effective cleansers, but they also strip away the natural oils that keep hair soft. Curly and coily hair is more prone to dryness because oils travel down a bend more slowly, so sulphates tend to leave curls feeling dry, frizzy and less defined. Switching to a sulphate-free shampoo is one of the first steps in the curly girl method for exactly this reason.
What should you look for in a sulphate-free shampoo?
- Look for: gentle cleansers (such as coco-glucoside or other mild surfactants), moisturising ingredients like shea butter, honey and natural oils, and "sulphate-free" stated on the label.
- Go easy on: washing too often — sulphate-free formulas are gentle, so 1–2 washes a week suits most curls, with a co-wash in between if needed.
Not sure how often to wash? It partly depends on your hair porosity — here's how to find yours.

Frequently asked questions
Why are sulphates bad for curly hair?
Sulphates are strong detergents that strip natural oils. Because curly and coily hair is naturally drier, that loss of oil leaves curls more prone to dryness, frizz and breakage — so a gentler, sulphate-free wash usually suits curls better.
Do sulphate-free shampoos still clean properly?
Yes. They use milder cleansers that lather less but still lift dirt, product and excess oil — they just do it without stripping your hair. If you use a lot of heavy product or oils, an occasional gentle clarifying wash helps.
How often should I wash curly hair with sulphate-free shampoo?
For most curls, once or twice a week works well, with a co-wash or water-only refresh in between. Low porosity hair may need a slightly more regular clarifying wash to avoid buildup.
