I suggest you get clip-on extensions because weaves hurt like hell (or so I heard). Clip-ons take like 5 minutes to put on and you can wash/style them as you would real hair if you get a good quality set. PLUS you can take them off when you sleep!

You can get a 7-piece clip on set at Abantu for $200. I've had mine since summer now and I've added dark ash brown highlights to them (since they were all blond when I got them) and the quality is still good.
