An oily scalp doesn't always need the harshest cleanser. These sulfate-free shampoos are pitched by their brands for oily roots or buildup. Some use olefin sulfonate, which still cleans quite hard. We flag it in the table.

Questions
What is the best sulfate free shampoo for oily scalp?
There's no single best one. All 16 listed here have no sulfates on the ingredient list, and the brand describes each as suited to this use. Start with the ones checked on the brand page, then compare cleansers and fragrance.
How do I know a shampoo is really sulfate-free?
Read the ingredient list, not the front label. Look for any ingredient ending in 'sulfate' (lauryl, laureth, coco-sulfate and so on). Sulfonates and sulfosuccinates are different ingredients.
Do you test these products?
No. We check ingredient lists and what the brand says the product is for, not how it performs.
