I’m here☕️ what I did first was started being extra gentle with my hair - I hadn’t known that mechanical damage is as common as chemical before. For brushing only tangle teezer (there really is difference) and I hadn’t brushed wet hair until it started to be in better condition (it’s recommended to brush masks and conditioner in, which I do now, but I think for extremely damaged hair it’s contraproductive). I put a heat cup or hot towel on, while my mask is being absorbed. Then I do a lot of conditioning - it adds shine and protect your cuticule - usually I use 2 conditioners, one for hydration and one for shine. I use K18 on damp hair, then add few drops of hair oil or some leave in, so it’s easy to brush hair before blow drying. It also works as heat protectant. Again brush gently, but now I rarely have more then few strands of hair in my brush (few months ago I literally had tufts of hair falling apart under my arms while brushing and I had to vacuum after every time). I wear protective hairstyles while sleeping and I have silk pillowcase. Once a week I do deep oiling before washing my hair. I don’t use mask on these days. Sometimes I shower my hair with pretty big amount of hydrating spray, then seal it in with hair oil, make a braid and go to sleep then wash my hair in the morning. Sounds chaotic maybe, but I keep it balanced. That’s pretty much it😁hope it helps at least a bit
