If Mark doesn't like it's a no go Cate.
Who's hair is it? Mark's or Cate's? (I have had my hair cut to a shorter bob style - not to my hubby's liking but he doesn't have to mess about with it in a morning!
why not give it a try Cate - you can always grow it back - yes it may take a while, but as least you can say that you gave it a try and it wasn't for you.
