I have read a lot on this board about extensions. Would you guys reccomend them, not reccomend them, etc? How expensive are they? Is it a lot of upkeep? I HATE bothering with my hair and I feel like extensions are going to be so much upkeep and MONEY that I'm thinking it might not be worth it. But then again, the self confidence it could give me would REALLY help. Any thoughts? Also, where does one get extensions? Can a normal salon do them?
