Haircut

I've been thinking about cutting my hair, because even though I cut it just before coming to London I just don't know what to do with it to make it look cool. I know I can make it work with the curling iron but then it gets damaged and lately I feel my hair has become really thin and I don't have the same amount I used to have so here are some examples of what I'm thinking of doing, although I'm scared and I don't know if I will do it in the end. I will let you know!!!
