Questions
Why care about conditioner after a keratin treatment?
Treatment brands usually give aftercare advice for both shampoo and conditioner. Only products whose own page says they're keratin-safe are listed here.
What is the best sulfate free conditioner for keratin treated hair?
There's no single best one. All 9 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.
Does salt matter after a keratin treatment?
Several treatment brands advise avoiding sodium chloride as well as sulfates. The table shows which products list it, so you can decide.
How do I know a conditioner 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.
