Hair stylist help.

I have EXTREMELY course curly hair and like an idiot I’ve over processed it. I’ve bleached it, I used to straighten it, it’s been dyed, just not good. Well I’m trying to get my hair back healthy. I’ve had it cut to get rid of what was split, dead, and beyond help so my hair is shorter now (used to be half way down my back and it’s now just below my shoulders. I no longer shampoo I use a cleansing conditioner (Renpur) every other shower but condition with nexxus intense moisture every time and do an over night deep condition once a month. Stopped dying and straightening my hair but it’s still dead feeling. I haven’t processed my hair for probably 2 months. My ends still feel like they are “fried.” Any tips to get my hair back in shape because I’m about to just shave my head and let it start over.
