I love his hair! When I first saw him in that episode, I couldn't help but stare. I kept on wanting the camera to go back to him. He's so cute! I went to school the next day, and acted like a screaming fangirl to all my friends shouting "OHMIGOD OMIGOD REID GOT A HAIRCUT IT'S SO CUTE!!!" And none of my friends watch that show on a regular basis like me, so they think I'm a freak. xD Well, I love his hair so much that I'm inviting one of my friends over so she can watch the episode and see it. xD
Matthew posted a picture of his haircut on his twitter page a few months ago, before the episode was aired, and then I thought it looked alright, but I'm not so sure anymore. I think I prefer him with long hair. Although I did laugh my ass off when Hotch asked him if he had joined a boy band.
I do like it. On his twitter, a while back, he put a picture up of it, he told the hairdresser to give him a haircut like Amelia Earhart. It was really funny and the team asked him about him joining a boy band. In my opinion, he looks younger. My friends hated him for his haircut before but now they like it. Overall it's cute but so is the long hair.
