Overall what would be your recommendations for a procedure that would better serve the interest of the patient the FUE or the FIT?
The difference between FUE (Follicular Unit Extraction) and FIT (Follicular Isolation Technique) is essentially in a name. The originators of the technique called FIT, in my opinion, could not get credit for an inventive breakthrough, so they simply changed the name. With that said, the FIT doctors use what they think is a different instrument (a sharp punch with a depth guard), something I used in the early days when I was originally exploring the technique and found no real advantage because any alteration in the angle of a sharp punch will cut through the graft and kill is. I believe that the use of a sharp punch of any type causes too much damage, so I rarely use it except for special cases where my biopsy shows that it has value and will not damage the hair. The best interest in patients is served by the least damage in the extraction process when these procedures are selected. There is enough difference between the tissues of one patient vs another patient that fine tuning the instrument (which instrument will be best for that particular patient) is critical (my opinion).

Minoxidil (Rogaine) can be a skin irritant for some patients and Retin A is an acid which burns the skin and will cause dryness. Some patients have told me they stopped using minoxidil because of this side effect.
