I have professionally dyed hair, but i want to dye my own hair blue/pink help!!?

my hair, right now is professionally dyed blonde, with some brown lowlights. My friend bought me pink and blue hair dye for my birthday/christmas and i want to dye part of my hair either pink or blue..or both. w/e.

do i have to bleach my hair, even tho it is very light blonde right now?

also do you think i should dye my tips of my hair, or like the underneath part of it? OR any other suggestions you may have :)

thankss!

You'll be fine; your hairs blonde enough for the dye to stick.

I'd suggest just the tips for dying it, I think it looks awesome and that way; if you get sick of having blue/pink hair you can just cut the tips of and get a killer new hairstyle.

The colour you choose is just up to your preference; personally I like pink.

However you do it; I'm sure you'll look lovely.
