What's the best Hair Extensions brand in USA? & What are the different types of Hair Extensions?

I've had long hair almost my entire life.. Want to be dramatic and chop it all off cause I'm a lil tired of taking 2 hrs every other day to blow dry & flat iron it now. It naturally has a mild wave to it if I don't style it. Anyways, I decided to go for hair extensions. Please guide me through the best hair extension brand in USA and also what are all the types is in there.*



Thanks in Advance.*
