Hi both my daughters get extremely matted hair. I’m finding it almost impossible to get the tats out. Does anyone have any suggestions for easy ways without having to cut it? They get big knots in and I’m probably not the best person to try and get them out as I have no idea about hair styling. They wash hair with shampoo and conditioner and then I spray on a leave in conditioner before trying to brush it. It’s driving me crazy and no matter what I do there’s still knots there that’s are impossible to get out. They both have thick hair one has wavy frizzy hair the other has straight thick hair. TIA
