What does it take to become a hair transplant doctor?

[Dr A's Clinic]

This is a question that is hardly ever asked.
So, this quiz is open to all.
e.g.

6 months to 1 year training
attend 2 to 3 days workshop
pay 2000 - 4000/- USD (no questions asked, you are welcome as a member of a society).
and so on.
We are not against any society as such as many are trying to improve standards.
However, readers need to know that there is no training requirement and none of the societies have any medicolegal standing.

So, what did you, as a reader, think it is required to become a good hair transplant surgeon.
