Will this cause hair damage?

[Cocoa 30]

Hi, I'm wanting to change the shade of the blonde I currently have, go a bit lighter. Will I be able to do this without too much damage? Will I have to have bleach or can they use a tint : toner? I am obviously getting it done professionally, however I don't want to book in to do it if it's going to cause damage as my hair is already quite dry. I've attached pics of now and what I'm trying to achieve.

Thanks pros!

Any sort of going lighter would take a toll on the hair especially blondes speak to an experienced colourist and book in for a consultation. He or She would suggest all the right products to get you there it may take a few session but your hair will thank you for it. Nothing worse that looking like a dry frizzy blonde I see plenty around
