Hair extension application methods? - hair extension methods

I am human hair extensions great efforts in a beauty salon. I know that their price is usually high. The freezing method (or so) is what I originally wanted, but it is too rediculously expensive. The hot method ('') is cheaper, to say, but the cold method is better for your hair? I am a little fog right now. What is the difference between the two applications and still worth the price of booking the application of Great Lengths way hot?
