What are the chances that I will go bald? How bald will I be? Can I know for sure? These are among the most common questions we get from patients in our hair loss consultations. Despite extensive knowledge about the mechanisms and causes of androgenetic alopecia (common baldness), the answers to these questions have been a bit hazy. New research has sharpened the focus on the genetic mix that results in hair loss and has enabled more accurate predictions. A study published in February 2017 in the journal PLoS Genetics identified over 250 gene locations newly linked to hair loss. Using this information, researchers more accurately predicted severe balding compared to previous methods.

Q: After a bad hair transplant, can you use lasers or electrolysis to remove the transplanted hair? — N.C. ~ Newark, N.J.
A: You can remove the hair in plugs with electrolysis, but it is difficult since the scarring distorts the architecture of the hair shaft and makes it hard to insert the electrolysis needle. Laser hair removal is a far more efficient way of removing the hair, but takes multiple treatments. However, the problem with either of these techniques is that the hair is destroyed and the underlying scarred scalp is not improved. In fact, it is made more visible when the hair has been removed.
Our preferred method of repair is to completely remove the plugs, dissect out the individual follicular units from those plugs and then re-implant them in the proper location and direction. In this way the hair can be reused and the appearance of underlying scarred scalp can be improved, as well as camouflaged with new hair.
Dr. Bernstein demonstrates how he places the tensioner on the patient in a robotic hair transplant procedure. The tensioner is a plastic picture frame-like device that adds tension to the patient’s scalp allowing for improved harvesting. It also has little dots, called fiducials, on its outer border which the robot “reads” for proper orientation. The robot scans the edges of the tensioner, reads the dots, and uses them to orient the robotic arm and punch tool.
Q: Is it ill-advised to comb one’s hair more than twice a day, especially hair that has been transplanted? Will frequent combing induce hair loss? — G.K. ~ Paramus, N.J.
A: Combing or brushing one’s hair does not cause hair loss – no matter how many times a day you do it. However, constant traction with braids or hair extensions can cause hair loss and this loss can be permanent.
Q: As a medical advisor and an end-user of the ARTAS Robotic System, do you see any impact of your involvement with Restoration Robotics? — J.V. ~ Miami, F.L.
A: Restoration Robotics has been very responsive to the needs of its physicians and to their patients. Because I work closely with Restoration Robotics in the development of new improvement and advances they are often introduced first in our practice.
Q: Dr. Bernstein, I am experiencing side effects on Propecia, are there alternative treatments? — J.D. ~ Roslyn, N.Y.
A: Yes, minoxidil (Rogaine), low level laser therapy (LLLT). Unfortunately, none of these will be as effective as finasteride.
Q: What do I do if I start experiencing side effects on finasteride? — L.L. ~ Riverdale, N.Y.
A: Don’t panic, just stop the medication and let your doctor know. He or she will give you guidance based on your symptoms.
Q: My hair is starting to thin in the front, but it is not yet bald. I have been going back and forth about whether to get a hair transplant or use Propecia. I’m not sure what my first step should be. What do you think? — N.K. ~ Pleasantville, N.Y.
A: In general, patients who are thinning, but not actually bald, should begin with combined medical therapy (finasteride and minoxidil) for at least a year prior to considering surgery. In many cases, with this regiment, surgery can postponed or even avoided completely. Unfortunately, some patients cannot tolerate finasteride or choose not to take it due to concern about potential side effects. Minoxidil, although useful, does not significantly alter the long-term course of hair loss when used alone.
