For those of you complaining about hair falling out/not growing - try therapro reconstructivor and the cellegen hairloss treatment spray. I've had trouble with my hair growing and being very dry and damaged (thanks to 3 rounds of accutane a few years ago), and this helped a great deal. My hair is longer (just below my shoulder blades) than it's ever been and it's in fairly good shape. It could still be healthier at the ends, but it's a huge improvement from what it was. I usually can find a good deal on it on ebay:

Fatima: you're from India, where women are known for having great, luxurious hair! We should be asking you! I tried an Indian hair oil once - I think it worked pretty well but my bf HATES the smell of it so he threw it away.

Also, I tried olive oil for a while but it left my hair greasy since it didn't seem to soak in very well, AND it stripped the highlights out of my hair. So, it's not a good idea if you dye your hair at all.
