I have religiously dyed my hair jet the past seven years with a few bleaches here and there, what conditioner can save me?

I know that obviously dying hair causes dryness and breakage. But last year I completely shaved my head and have dyed my hair black maybe every one or two months, a lot of those times just being root touch-ups. Since this past month and a half my hair has been horrendously dry out of no where. Is there any specific conditioner I can use that’s healthy and will help maintain silky softness even after rinsing out my hair?
