OMG WTF?
You don't go looking for hair transplants, the salons that do them will find you and your balding head. Why is this so hard to understand? Furthermore, you don't say that you have any personal connection with any of these salons, it's like you're looking for a hair transplant, any hair transplant from anyone who'll take you.
Every salon is different. Perhaps you can tell us some more about your experience with your hair and why you feel that a hair transplant is right for you. It's a very expensive procedure that lasts for a lifetime and I'm just not comfortable with your approach.
Hair transplantation is a very serious matter you know
