Ombre is all the rage right now. I'm a huge fan of this brown-to-blonde look. I've tried the ombre myself and I must say, it's a fun way to try out a new style with not too much commitment. Don't love the blonde on the ends? Trim it off!
What I do to get loose curls is rap a rather large piece of hair around my wand and hold it there for 15 to 10 seconds. When I'm done with all of my hair i separate the curls into two and I get wavy, loose curls.
