But the bottom line is the cap on the bottle is worth more that the contents in most cases, even for the most expensive of shampoos. What goes into the cost of a procedure depends solely on the doctor or clinic doing it. Naturally there are costs that are the same for all. Things such as standard medical supplies, office space, and normal business overhead and staff. Beyond that there are the different methods, equipment and marketing costs which vary greatly from one to another.
New techniques are also expensive.
Lasers can cost tens of thousands of dollars. Trademarks, patents and unique devices costs thousands more. Videos, magazine and television spots can be extremely expensive. Even the ones that don't advertise all have some sort of informational package they can send you or can direct you to their web site. I can not think of a better solution to the embarrassing subject of hair loss that this new medium we call the world wide web.
