I have read that Artas works best on straight black hair. Is this an option for gray hair? Wavy or curly hair?

The ARTAS
robot is able to perform on dark hair, blonde hair, gray hair, very curly hair,
and ethnic hair. With ethnic hair we use a 1.0mm punch instead of a 0.9mm
punch. People who have white or light blonde hair need to have their hair dyed
before (or we can do it in office) the Robotic FUE procedure in order for the robot
to best visualize the hairs.

ARTAS can be used on a variety of hair types. Grey or white hairs can be treated with hair dye prior to the procedure.  Wavy and curly hair can also be treated with ARTAS.  The ARTAS surgeon can change parameters to suit the hair type. 

Generally speaking the Artas is fine with wavy or curly hair.  Where it is not as good is if the hair curls under the skin or hooks under the skin. In general, I prefer FUE by hand with a skilled surgeon every single time vs the Artas.  The times when the Artas is good is when the doctor is older and gets tired performing FUE, or for more inexperienced doctors trying to learn FUE.  What most patients don't realize is the punch size used on the Artas is very large compared to a skilled surgeon doing it by hand, and that a lot of practices with an Artas do not have the experience to perform a very successful procedure with it.
