So do you guys try to use sulfate free shampoo and conditioner and like other hair products? Recently, I feel like the last few years I've heard a lot about how you're not supposed to use sulfates on your hair, but then I've seen this like trend on TikTok of people saying that if you have like hard water, which most people do, that you kind of need sulfates sometimes to like break that down on your hair, I guess, and like take off that film. I'm wondering your guess's thoughts on this or if you know any more information.
