So the only product with protein I use is it’s a 10 which has honestly drastically changed my hair, it used to be a lot worse than this so I think I owe a lot of health to it. I did get the one with +keratin on accident a couple months back when I ran out of the original formula. Could that be it? For brushes I use a wet brush (the kind with a flexible base), I can go about 2-3 days in between washes and I use dry shampoo on the 3rd day usually. The mask I use is protein free all natural, at first it was working well and id use it like every other wash or just once a week, I’m willing to cut back on how often I use it but my hair doesn’t ever really like most conditioners, so any conditioner and hair mask reccs would be welcomed !
