Questions
Why does gray hair turn yellow?
Sun, hard water, heat styling and product buildup can all give gray or silver hair a yellow cast. Violet toning shampoos counter that tone.
How often should I use a purple shampoo on gray hair?
Brands usually suggest once or twice a week, swapping in a regular gentle shampoo the rest of the time. Leaving it on too long can give a lilac tint.
What is the best sulfate free shampoo for gray hair?
There's no single best one. All 5 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.
