I think highlights will be less damaging, because they need less touch ups, and you're not bleaching your whole hair, just parts of it.
But, you have to consider if the colour is worth all the damage to your hair. Your hair will be likely to be more porous and dry and you can also suffer from breakage.
highlighted 3a hair. Fine, medium to high density. Not shure about porosity. Below shoulder blade lenght, aiming for waist!
