Boy; Change hair color to blond / get highlights?

Tweet

Hello, I'm wondering whether or not to dye my hair blond, I'm 16, I've got (dark-)brown hair, and I've never dyed my hair before! (This is me: hair's more of a quiff currently!) So, should I do it? I'd like to have it similar to the hair in these pictures: -http://scontent-a.cdninstagram.com/hphotos-xfa1/t51.2885-15/e15/10952963_1554287254827426_1298352638_n.jpg -http://scontent-b.cdninstagram.com/hphotos-xfa1/t51.2885-15/e15/10979654_261210280715848_1968894870_n.jpg Any and all advice is appreciated!
