Dr. Bernstein and Dr. Shaver answer frequently asked questions about hair transplantation, hair loss, and medical treatment for hair loss.

Q: I’m a 42 year old African-American woman and I’m losing hair on the crown of my head. Would I be a good candidate for a hair transplant? — E.E., Philadelphia, P.A.

A: Hair loss in the crown of an African American female can have several different etiologies, so the first thing to do is to make the right diagnosis. The most common causes of hair loss are androgenic alopecia (AGA) and scarring alopecia, also called ‘Central Centrifugal Cicatricial Alopecia,’ or CCCA. A biopsy is often useful to differentiate these two causes of hair loss when the diagnosis is unclear. A biopsy can also identify other, but less common, causes of crown hair loss.

AGA presents with a history of gradual thinning in the front and/or top of the scalp, a relative preservation of the frontal hairline, a positive family history of hair loss and the presence of miniaturization in the thinning areas. Miniaturization, the progressive decrease of the hair shaft’s diameter and length in response to hormones, can be identified using a hand-held device called a densitometer. If the diagnosis is AGA, then a hair transplant can be very successful provided there is enough donor hair.

CCCA presents as a progressive form of scarring alopecia that occurs almost exclusively in African American women. The onset of CCCA is very slow, typically developing over the course of years. CCCA starts near the vertex or top of the scalp and spreads in an outward direction. The involved area is usually smooth and shiny with decreased hair density.

Central Centrifugal Cicatricial Alopecia is diagnosed with a scalp biopsy performed in the area of hair loss. Those patients with CCCA are generally not candidates for a hair transplant procedure since the body may reject the transplanted hair. This condition is better treated with oral and injectable anti-inflammatory medications. Surgical treatment for cosmetic benefit may be an option in some cases after the disease has been inactive for many years.

Q: Does Follicular Unit Extraction performed by a robot hurt more than regular FUE? — R.T., Greenwich, CT

A: As with manual FUE, robotic FUE hair transplantation is an outpatient procedure performed under long-acting local anesthesia – a combination of lidocaine and bupivacaine. After the initial injections, the patient does not experience any pain or discomfort.

Before starting local anesthesia, we give most patients oral valium and intra-muscular midazolam (a very fast acting sedative that is very relaxing). While some patients doze off at the beginning of the procedure, others prefer to watch TV, a film, or just chat.

Local anesthesia generally wears off after 4-5 hours, so for transplant sessions lasting longer than this, we will give more anesthesia before the first wears off. With Robotic FUE, there is no discomfort once the procedure is completed and the anesthesia wears off. This is in stark contrast to an FUT strip procedure which can be uncomfortable in the donor area for days to weeks.

Q: Can I play a contact sport, like football, right after having a FUE procedure? — C.N., Easton, P.A.

A: I performed a study (“Graft Anchoring in Hair Transplantation,” Dermatologic Surgery 2006; 32: 198-204) to answer a simple question, one that patients ask all the time: at what point are transplanted grafts so securely anchored in the scalp that they cannot be dislodged?

In the study, it was found that after 10 days the transplanted grafts become a permanent part of the body such that no amount of scrubbing or combing can dislodge them. So, while there are generally no limitations on strenuous exercise after a FUE procedure, we recommend waiting at least 10 days before playing any contact sport, like football, as the grafts could be dislodged if vigorously rubbed.

Q: How does laser therapy work?

A: The actual mechanism by which Low Level Laser Therapy (LLLT) stimulates hair growth (i.e., increases the anagen phase of the hair cycle) is still unknown. Possible mechanisms include the following:

  1. Stimulating the production of various growth factors (insulin-GF, vascular endothelial-GF, fibroblast-GF)
  2. Dilating the blood vessels of the hair follicles
  3. Increasing the production of ATP (molecular energy) in the cells through its effects on mitochondria.

Q: How Many Hair Transplants Will I Need? — E.E., New York, N.Y.

A: The first session of a hair transplant should be designed as a stand-alone procedure with the following three goals:

  1. Establishing a permanent frame to the face by creating, or reinforcing, the frontal hairline.
  2. Providing coverage to the thinning, or bald, areas of the scalp with the hair transplant extending at least to the vertex transition point.
  3. Adding sufficient density so that the result will look natural.

Achieving all of these goals will allow the first procedure to stand on its own.

Because of this, many people feel one hair transplant is sufficient.

Reasons for Second Hair Transplant

While the first session of a hair transplant is designed to stand on its own, there are several reasons why one would want a second hair transplant, such as increasing the density in a previously transplanted area; refining the hairline created in the first transplant; focusing on increased crown coverage, when appropriate; or addressing further hair loss that’s occurred after the first transplant.

Because of this last reason, addressing further hair loss, careful patient evaluation and surgical planning is needed to take into account your donor reserve and the likely extent of any future balding in the planning of your first transplant session.

Wait at least 10 to 12 months Before Getting a Second Hair Transplant

If a second transplant is warranted, patients are advised to wait at least 10 to 12 months after the first transplant before considering a second. This is because over the course of the first year, the first transplanted hairs have grown in and the progressive increase in a hair’s diameter, texture and length can markedly change the look of the hair restoration — this may influence the way a patient wants to groom his/her hair, and only after the hair has reached styling length can the patient and physician make the best aesthetic judgments regarding the placement of additional grafts.

For patients having an FUT (strip) procedure, another reason to delay a second hair transplant session for this time period is that scalp laxity will continue to improve making the donor hair easier to harvest.

Q: I’ve heard that using Propecia and/or Rogaine is a good idea after having a hair transplant, but are they mandatory? — B.M., Short Hill, N.J.

A: Neither finasteride (brand name: Propecia) nor minoxidil (brand name: Rogaine) will have any effect on transplanted hair. That said, while you don’t need them to protect your transplanted hair, you will likely have original hair interspersed among your transplanted hair that will continue to thin and fall out over time. This vulnerable hair can be protected by finasteride which has been shown to reduce future hair loss significantly; additionally, you can add Rogaine for extra benefit.

However, with Propecia, you should only use it if you can commit to it long-term because it takes up to a full year to see any effect. With Rogaine, you should only use it if you can commit to using it continually and regularly – you should not stop and start it.

Q: How many follicles can you transplant with robotic FUE compared to manual FUE? — R.V., Upper West Side, N.Y.

A: We can extract the same number of follicles robotically as we can manually.

That said, the goal of any hair transplant procedure is not to transplant as many hair follicles as possible but rather to achieve the best possible cosmetic result given your degree of hair loss and the number of hair follicles available in your donor area.

While there is no difference between robotic and manual FUE in terms of the number of follicles that each procedure can extract, robotic FUE does have the following advantages over manual FUE:

  • During the follicular unit extraction (or harvesting) phase of a hair transplant, there is less chance of damaging follicular units using a robot vs. a hand held device (e.g., Neograft), because the robot is more accurate. This means more grafts survive after transplant.
  • Robotic graft harvesting times are shorter than manual, e.g., while on average if a physician could manually extract 200-300 grafts per hour, the same physician could robotically extract up to 500-1000 grafts per hour ((Chang, H.H. Robotics, artificial intelligence, and the future of hair transplantation. Prime Dermatology, July/August 2014.)). This means a shorter procedure time for the patient.

Q: I am 26 years old and have been suffering from hair loss for 8 years. I have been on Propecia (finasteride) and Rogaine (minoxidil) during those years. Unfortunately my hair loss has continued to progress aggressively. I am of half African and Caucasian descent, and my hair is curly. I understand that there are certain limitations on having hair transplants before you are 35, however I do not mind having another transplant in a few years, if necessary. — A.L., Rye, N.Y.

A: Although it is possible to have a hair transplant to the crown using robotic FUE in African American patients, given your young age and that you state your hair loss is progressing aggressively while on Propecia and Minoxidil, it is likely not a good decision to have surgery at this time.

The reason is that as your hair loss surrounding the crown expands over time, it may look unnatural to have hair transplanted solely to the crown region.

At your age, it is best to take Propecia (finasteride) and Rogaine (minoxidil), and if a transplant is indicated, to start at your frontal hairline and top of your scalp, the areas that will be most important cosmetically long-term.

Q: I’ve heard that your ARTAS hair transplant robot can now create the recipient site in a hair transplant procedure. Has it been done on humans or is it still in an experimental phase, and if so can you tell if it looks as natural as when the surgeon does it? — P.S., Miami, Fl

A: In February 2014 we introduced new technology that allows the ARTAS Robotic System to assist the surgeon in recipient site creation. We are now using the ARTAS robot to make recipient sites in select hair transplant procedures. If designed and programmed properly by the doctor, robotic assisted recipient site creation can produce a hair transplant result that is as natural as when the surgeon does it by hand.

Q: I heard FUE is a scarless surgery. Is this true using any of the current FUE methods (ARTAS® robot, Neograft, manual FUE)? — V.S., Weston, C.T.

A: All hair transplant procedures, follicular unit transplantation (FUT) and follicular unit extraction (FUE), leave scars. FUT produces a linear scar at the back of the scalp that may be visible if you keep your hair short. FUE, on the other hand, leaves small dot scars at the back of the scalp that are not visible if you keep your hair short. These tiny scars will happen regardless of which FUE method is used, i.e., ARTAS robot, SAFE system, Neograft, or manual FUE. Some physicians who use the Neograft method advertise that there is no scarring involved when using the Neograft; however, this is not true: however, this is not true: there is some scarring associated with all FUE methods that increases with the total number of grafts harvested.
