Synopsis: A major advance in Follicular Unit Extraction is the introduction of a robotically controlled, image guided system to remove intact follicular units directly from the scalp. The robotic device increases the accuracy of graft harvesting, which in turn minimizes damage to hair follicles and reduces harvesting time. Each of these factors potentially contributes to increased graft survival. The technology also enables FUE to be performed on a wider variety of patients. This paper discusses this new robotic technology.
Q: If I have no linear scar and I can exercise right away, why would you ever recommend FUT instead of FUE? — H.T., Dover, M.A.
A: I advise FUT because the grafts are of better quality (less transaction and more support tissue surrounding the follicle) and because more hair can be obtained from the mid-portion of the permanent zone –- which is where the hair is the best quality and most permanent. For the majority of patients a linear scar buried in the donor hair is not an issue. Each patient has to weigh the pros and cons of each procedure when making a decision.
Q: After achieving results with 5% Minoxidil is it possible to the switch to the 2% version to maintain those results without any adverse hair loss? — I.I., Winnetka, Illinois
A: It will be less effective. The dosing should not be decreased.
Q: Have you any experience with Azelaic Acid as a hair loss treatment — is this something you would recommend using with Rogaine (minoxidil) 2% or 5% solutions? — S.V., Short Hills, N.J.
A: Azeleic acid has no direct benefit in promoting hair growth. Azelaic acid (like retinoic acid) increases the absorption of minoxidil, but also the side effects, so I would especially not recommend it in your case.
Q: Is it possible that side effects attributed to the use of Minoxidil 5% lotion can reduce over time or disappear altogether? Specifically I experienced a heightened sense of heart activity (palpitations). — D.D., Bronxville, NY
Q: A while ago I saw you and you recommended FUT hair transplantation, but my friend came in and you recommended FUE. How come? — C.T., Hackensack, N.J.
A: I think that both procedures are excellent, which is why I do them both. My recommendations are determined by the individual patient. His or her age, desire to wear hair cut very short, athletic activities, donor density and miniaturization, extent of hair loss, and potential future balding are all important aspects in the decision process.
Q: Is the recovery time a lot longer with FUT compared to FUE? — C.W., Chicago, I.L.
A: Cosmetically, the recovery for FUT is actually shorter, since the back and sides do not need to be shaved and the longer hair can completely cover the donor incision immediately after the Follicular Unit Transplant procedure. In large Follicular Unit Extraction procedures, the entire back and sides of the scalp need to be clipped very close to the scalp. It can take up to 2 or 3 weeks for the hair to grow long enough to completely camouflage the harvested area. Once the healing is complete and any redness has subsided, the hair can be cut shorter.
Q: I am an African-American man with tight curly hair. Will the FUE robot be able to work on curly hair? — E.O., Manhattan, N.Y.
A: Yes, the ARTAS robot for FUE can be adapted for African-American hair when performing follicular unit extraction. We use a punch that is 0.1mm wider in diameter than the instrument used for Caucasians. It allows us to incorporate the slightly larger volume of tissue that results from the curved hair and enables us to accomplish the hair transplant with less in jury to follicles than if a smaller instrument were used.
Dr. Bernstein was quoted in an article on robotic follicular unit extraction (FUE) that appeared in Brazil’s Veja Magazine. It is titled, “Vai Ficar Mais Fácil Deixar de Ser Careca,” which translates to, “It Will Be Easier To Stop Being Bald.”
Q: I read on your blog that the ARTAS robot doesn’t work well in patients who want FUE but have blond hair. I have dark skin and hair, does that present a problem for the machine? — J.S., London, England, U.K.
A: The ARTAS Robot performs follicular unit extraction just as well with blond hair as dark hair, but not white hair. It is simple to just to dye the white donor hair prior to the procedure. This donor hair will be clipped very short the morning of surgery removed anyway, so it will not present too much of a cosmetic issue.
