The answer to this is yes and now. IF you are young (under 26) and male and have a hair transplant without taking the drug finasteride, you might develop shock loss which will accelerate the hairs that are miniaturized and in the process of being lost. Minoxidil does not impact normal hair.
H. George Brennan, MD, FACS - Account Suspended says:
The donor hair will only grow at the recipient site. If you do the procedure with the modern technology, then there is no residual scar or evidence of donor extraction which is the beauty of the new technology. There's no incision, no scar, and no pain! Best of luck,
Hair transplant will not pull on your facial skin. The back of your scalp may feel tight for several weeks but it will not impact your face. You do NOT get a face lift or a neck lift with hair transplant surgery.
