What are you looking for?
Foremost: you are looking for a shampoo that cleans your hair but does not strip it too much of much needed oils.
Next: sulfates are very strong detergents so they do tend to strip black hair too much. Sulfates in themselves are not dangerous or harmful to health they are just "too effective" at cleaning. This is okay for greasy Caucasian and Asian hair but not generally for black hair.
So what to do?
Firstly, look for a sulfate free shampoo. In many places these are still very hard to find because sulfates are the commercial standard for shampoos.
If you cannot find a sulfate-free shampoo, people have tended to take one of two paths:
- They stop using shampoo altogether and wash their hair with conditioner. The problem here is that some people claim that they've incurred breakage as a result of co-washing only.
- Others find a moisturising shampoo. Even though it contains sulfates, it has ingredients that counteract their action a little by adding back moisture where they have stripped it away.
