I think I have an obsessive habit of changing my hair color every few months. It was ombre, then brown, and now blonde! But I like experimenting with different styles and seeing what looks best on me. I think summer is the perfect time to try a new color or cut because it's not as much of a shock as it would be if you just walked into school with it, knowing everyone would be noticing.
As for what I asked for, I showed my stylist a photo of me with my ombre hair, and told her I wanted to be all the blonde color that the bottom half of my hair was in the photo. It turned out pretty spot on! I also got a simple trim, because my hair is always a little dead at the ends when I get it done.
