Welcome! Did you actually bleach your hair, ie. persulphate bleach, or did you just lift with peroxide? If the latter there will be some damage but probably minimal, you should be doing regular hydrolysed protein treatments and coconut oil treatments.

What you should do is strand tests as with any colour process, initially on shed plughole hair then on your head if the shed hair looks promising. Your ends might be more porous from normal weathering, from mechanical damage, from UV light or heat styling, so they may absorb more colour, in which case you treat the less porous section first then apply to the more porous section to get an even colour.
