How are Recipient Sites Programmed into the ARTAS Robot?

December 18th, 2015

Q: How are specifications for making recipient sites inputted into the ARTAS® robot? — A.F., Queens, NY

A: At the outset of the procedure, the physician sits at a computer terminal that is connected to the ARTAS Robot and enters the specifications directly into the robot’s software. Variables programmed in this manner include the number of recipient sites, density of sites, angle that the hair will extrude from the skin, depth of recipient sites, and the minimum distance away from existing hair follicles that a site can be created.

Will Robotic FUE Reduce the Cost Per Graft for FUE Procedures?

December 17th, 2015

Q: Will the ARTAS robot result in a lower cost for an FUE hair transplant? — F.K., Ditmars Boulevard, NY

A: Robotic FUE may cost slightly more per graft than a typical manual FUE procedure due to the greater expense of this new technology. At Bernstein Medical, we use the ARTAS Robotic System for all Follicular Unit Extraction (FUE) procedures.

How Does the ARTAS Robot Avoid Transection of Hair Follicles During Recipient Site Creation?

December 16th, 2015

Q: How does the ARTAS System avoid damaging hair follicles in the balding area during recipient site creation? — R.K., Brooklyn, NY

A: The ARTAS robot‘s optical guidance system enables it to accurately create recipient sites in areas of thinning hair without damaging existing hair follicles. During the recipient site creation process, the robot uses its advanced image-guided optical system to scan the surface of the skin, locate existing hair follicles in the recipient area, and then create recipient sites at a specified distance from these existing hairs.

The ARTAS robot carries out this process rapidly, accurately, and consistently according to the physician’s programmed specifications. Thanks to the microscopic precision of the image-guided technology, the robotic hair transplant system can avoid injury to follicles that can result when Follicular Unit Extraction (FUE) is performed using manual techniques.

What Is Your Opinion on Doctors Performing Only FUT or Only FUE?

June 22nd, 2015

Q: It seems that some doctors offer only FUT and others only FUE. What is your opinion on that? — D.E., Portland, M.E.

A: Both FUT and FUE are excellent techniques, but have different indications. To deliver the best care for our patients, hair restoration physicians should have expertise in both procedures, and they should offer both in their practices.

Update: I have expanded the answer to this question in a new Answers post.

Does Propecia Work in Older Patients?

June 20th, 2015

Q: Hi. I am 52 years old and wish to know if Propecia will work for people my age. I have started losing some hair a couple of years ago and it’s thinning out. Thank you very much for your help. — K.E., Boca Raton, FL

A: Propecia (Finasteride 1 mg) can hold on to hair at any age, but works best to re-grow hair in those who are younger.

The reason is that finasteride works to reverse miniaturization (the thinning and shortening of hairs due to DHT). Younger patients, with early hair loss, generally have more hair in the early stages of miniaturization where the changes are readily reversible.

Older patients are more likely have more advanced miniaturization or areas that are totally bald and will thus not regrow with medical therapy.

What is Platelet-Rich Plasma (PRP) and How Does It Promote Hair Growth?

June 17th, 2015

Q: I’ve heard a lot about platelet-rich plasma (PRP). What is platelet-rich plasma, and how does it promote hair growth? — A.V., Scarsdale, NY

A: To begin, first let’s define a few basic terms: blood plasma, platelets and PRP

What Is Blood Plasma?

Blood plasma holds the blood cells in a liquid suspension. Blood plasma makes up about 55% of the body’s total blood volume. There are three basic types of blood cells: red blood cells (that carry oxygen), white blood cells (that have immune functions to help fight infection) and platelets (that facilitate coagulation, wound healing and repair).

What is a Platelet?

A platelet is a type of white blood cell containing approximately 50 to 80 tiny encapsulated structures called alpha-granules. Each alpha-granule contains a high number of growth factors, many playing a fundamental role in healing following tissue damage.[1] Many of these platelets are also known to regulate the growth cycle of hair follicles.[2]

Platelets are formed in the bone marrow and circulate throughout the bloodstream in a concentration of approximately 140,000 to 400,000 platelets/mm3.

What is Platelet-Rich Plasma?

Derived from a patient’s own blood plasma, platelet rich plasma is concentrated blood plasma which contains approximately five times the number of platelets and growth factors normally found in the blood.

How Does Platelet-Rich Plasma Work to Promote New Hair Growth?

Studies that have looked at the therapeutic effects of PRP on hair loss have found that it promotes hair survival and hair growth in both laboratory studies[3] and human clinical trials, but exactly how PRP promotes new hair growth isn’t clear. Researchers have suggested a few possible mechanisms.

In a recent pilot study[4] that found that PRP injections resulted in noticeable improvement in both males and females with androgenetic alopecia, researchers suggested that PRP may have stimulated hair growth by prolonging the anagen (growth) phase of the hair follicle.

In another study[5] that showed PRP promoted hair growth in males with alopecia, researchers suggested that PRP may have protected the hair follicles against one of the possible main mechanisms of pattern hair loss: the death of dermal papilla cells in the hair follicle.[6] The death of these cells leads to a gradual shrinking and eventual disappearance of the hair shaft, a process called miniaturization.

Other studies have observed that PRP seems to promote the growth of new blood vessels around treated hair follicles. Because of this, researchers have suggested that the growth of new blood vessels may be helping to stimulate new hair growth.[7]

In sum, while published studies so far suggest that PRP therapy is a safe and effective treatment option for male and female androgenetic alopecia, there is still a need for more extensive studies to better understand the mechanism by which PRP treatments promote hair growth.

Can I Have Platelet Rich Plasma Therapy Instead of Hair Transplant Surgery?

June 11th, 2015

Q: It was recommended by the doctor that I have a hair transplant. Can I do platelet rich plasma (PRP) instead? — W.D., Denver, CO

A: PRP will generally be inadequate for patients who are candidates for a hair transplant. PRP works to reverse miniaturization (thinning hair) as do other medical treatments (Propecia, Rogaine, LLLT). Unfortunately, medical treatments do not grow hair back once it has been lost.

Does Platelet Rich Plasma (PRP) Therapy For Hair Loss Involve Surgery?

June 10th, 2015

Q: How is platelet rich plasma therapy for hair loss performed? Does it involve surgery? — T.A., Tribeca, NYC

A: Platelet rich plasma (PRP) therapy for hair loss is performed during a simple office visit, takes about 30-45 minutes, and does NOT involve surgery.

The first step in PRP treatment for hair loss involves drawing a patient’s blood into a syringe.

Next we use a double-centrifuge platelet concentration system (the Emcyte Pure PRP system) to separate and then concentrate platelet-rich plasma from the blood.

The last step involves transferring the platelet-rich plasma into a syringe and then injecting the plasma directly into the patient’s scalp.

After the treatment, some patients may experience very temporary soreness and/or swelling, but many patients will experience nothing.

After the initial treatment, patients will typically receive two more treatments at 6 week intervals. After that, they will receive additional treatments every 3 months over the course of the first year. After the first year, patients will receive treatments approximately every 6 months.

Are There Any Side Effects or Safety Concerns in Using PRP to Treat Hair Loss?

April 20th, 2015

Q: I’ve heard about using platelet rich plasma (PRP) therapy to treat hair loss. Are there any potential serious side effects that I should be aware of? — L.S., Roslyn, Long Island, NY

A: PRP is a therapy that has been used since 1987 to help promote the healing of hard tissue (bone, joints) and soft tissue (skin). To date, there have been no reported major side effects.[1]

Only a handful of published studies have tested PRP’s effectiveness and safety in treating hair loss; however, none of those studies have reported serious side effects.[2],[3],[4],[5],[6],[7]

This lack of any reported major side effects coupled with the fact that PRP is obtained from a patient’s own blood makes doctors relatively confident that PRP treatments are safe for hair loss.[8]

All this said, researchers are continuing to evaluate both the efficacy and the safety of PRP therapy for the treatment of male and female pattern baldness.
