Now the one thing to be careful about is where you get it dyed. NEVER DYE YOUR OWN HAIR. Also having a friend do it isn't always the greatest idea. Even though it may be cheaper and fun to do with a friend believe me the outcomes are noticeably different (and not as good) as if you were to get it done at a salon. There are many places that will do it fairly cheap and you can always trust that it will be done well.
Now if you are a bit worried about dying your hair let me just tell you: hair is hair, it grows back and it can be cut off. If you're a person who is very "attached" to your hair and you don't want to risk dying it then don't; but if you're ready for a change then go for it!
Here are just a few photos of hair I love and will someday have done to my hair :)
Here is my hair when I dyed parts of it purple last summer :P
Highlights and Fun with Blond Hair - Many people love highlights (I don't really) so here are two variations with lighter hair. The left picture the girl had died her whole head blond and as it grew out she got roots but now it actually looks really cool. Dying the end of your hair is really fun easy and if you hate it you can just cut it right off. The second picture on the right the girl dyed the undersides of her hair blond (after bleaching). This is a great look because as it grows out you won't see the roots and it gives your hair a peekaboo feel.
Daring Hair - Purple: one of my favorite colors and so fun for hair. If you want to stand out and not bleach you hair (as long as your hair isn't dark you won't have to bleach it) go for a purple or blue or black! Experiment, ask your hairdresser what they suggest, they always know what will look good don't be afraid to talk to them!
So these have been just a few ideas I hope they help and inspire you!
I will post the pictures of my new hair later :)
