Any hair product recomendations to keep it healthy?

So i am dying my hair blue its going to be semi permanent but the thing is that my hair is natuaraly black so of course i have to bleach it i know that bleaching it and dying it will leave my hair dry and wraspy and it will be damaged. What are some hair products that you recomend me to use to get my hair back to healthy but without ruining the new hair color and not make it bleed? Ex. Shampoos conditioning ect ect
