While typically a safe and effective cleanser, sulfates can sometimes be simply too good at their job — washing away more oil than needed, and leaving hair feeling dry and brittle or the skin and scalp feeling itchy and irritated. For those who have just undergone a keratin treatment, regular use of sulfates can contribute to the breaking down of the chemicals used — giving you less proverbial bang for your (typically quite expensive) buck.

However, you’re probably safe to keep using a sulfate shampoo you love if you’re solely concerned about color; experts like cosmetic chemist Randy Schueller have said it’s not the culprit behind fading color, though stripping your hair of essential oils doesn’t help the damage.
