Will dyeing my hair damage it a lot?

So I got this new hair dye called Splat and the color is luscious Rasberry. I'm not going to be bleaching it since my hair is already naturally light and almost bleach blonde. I've dyed my hair a couple of times but I love my hair and I really want to know if it will get really damaged. I know it will get somewhat damaged but how much? Will deep conditioning and only dyeing my hair 3 times per week help?
