Hair dye tips and help?

So I'm going to grow my hair down to my knees and might dye it with Stargazer Hair Dye (Tropical Green). It would be new and healthy hair, but if I dyed, which will include bleaching all of it, would that end up me having worse hair than I did before? My hair is thick and I have dyed it with bleach, black, blue, etc. It has survived perfectly fine. But...IF I BLEACH THAT MUCH HAIR WOULD IT BE IN WORSE CONDITION THAN BEFORE? Is it even safe to dye that much hair over having my hair short and bleached? Thank you~!!
