I'm going to get my hair cut soon, and I don't know if I should change my hair color while I'm at it. It's all natural, but sometimes I think it's really boring, and I don't know what I could do that would look good on me.
I'm 18 years old so I don't want something too young nor too old. Any suggestions are welcome. :o

I think that color is really pretty on you actually. It makes your eyes stand out. If anything, just get a few highlights. =)

Zoe is right. Your hair colour really does suit you.
But if you fancy a change, you could maybe get a few highlights or a flash of colour on one side. Something like this http://ny-image0.etsy.com/il_430xN.19970608.jpg

Some highlights will be nice. It's not a very drastic change, but it's still a nice change.
