Extensions there range from $900 to $1500 dollars, not cheap. Typically they won't even give you extensions unless your hair length is touching your shoulders. Sorry about your bad haircut, but if your hair is at least to your shoulders and you have the money to spend then go for it, otherwise I would start experimenting with different hair styles!
