In a standard hair transplant procedure (follicular unit transplant through strip technique), having adequate scalp laxity is crucial to avoid complications in the donor area. Doing so has required the individual judgment of an experienced hair transplant surgeon but still leaves room for human error. If the surgeon removes too wide of a strip, there may be issues with wound closure, a visible wide scar, telogen effluvium (hair loss around donor wound), and/or skin necrosis. Areas around the scalp most at risk are the mastoids or the area behind ears.

Laxometer has been designed to minimize hair transplant complications (in 15th annual meeting of International Society of Hair Restoration Surgery) by helping assess scalp laxity more accurately prior to a hair transplant procedure. After the first assessment, the patient then practices the scalp exercise to increase mobility and is then reassessed the day of surgery. The more laxity the patient has the higher the chances of increasing the number of grafts that can be transplanted in a single hair transplant.

We performed a study on 37 different patients to assess the success and functionality of laxometer. In all of these patients, half of the donor wound was closed during the procedure to evaluate the impact of donor excision on the laxity of the donor area. Three (3) locations of donor area were assessed before and after incisions were made:

I.    Right side
II.    Mid line
III.    Left Side

The laxity of the sides were measured approximately 10-15cm above the mastoid bone from the midline. The incision was made using a double bladed knife to insure uniformity.

After excising the first half of the strip, laxity was measured on the secondary section prior to full incision and excision. If laxity has been compromised due to the first excision and closure, then the second incision will be smaller. Out of the 37 patients that underwent follicular unit transplantation through strip technique, only six (6) patients required a smaller incision due to a lesser laxometer reading caused by reduction of laxity. Our study shows that wound tension:

I.    May increase on the secondary side in some patients (~16% chance)
II.    May not be an issue in most patients (~84% chance)

Laxometer helps determine scalp laxity before, during, and after a hair transplant procedure for optimal excision and closure. It helps determine the maximum amount of tissue that can be excised safely helping increase the chance of more grafts that can used a single session. This practice is best applied on patients undergoing a mega-session hair restoration in which over 2500 grafts are being transplanted in one hair transplant session.

The article “Surgeon Restores Patients’ Hair, Self-Confidence” was recently published in the popular newspaper of “The Beverly Hills Courier” based on the interview with Dr. Parsa Mohebi, medical director of US Hair Restoration.

Here is a summary of the article, which mostly focuses on the psychological impacts of hair restoration on men. Dr. Mohebi also discussed some of the new methods of hair restoration that is offered by the Beverly Hills Office of US Hair Restoration. Here is how he goes:

Nothing looks better than a full head of hair, and one of the best people to provide it is Dr. Parsa Mohebi, medical director of US Hair Restoration.

Mohebi specializes in several hair-transplant procedures:

• Follicular Unit Transplant (FUT) is the gold standard of hair-transplant surgery, Mohebi said, giving very natural results. A strip of donor scalp is removed and the follicles are prepared under microscopes and distributed in the bald area in the natural direction and orientation.
• Follicular Unit Extraction (FUE), also called non-invasive hair-restoration surgery, uses special biopsy devices to extract individual follicular units without having to remove a strip of skin; so there is no linear scar.

“Not everyone needs non-invasive surgery,” Mohebi says. “But people who want to shave their head in the future for any reason may consider FUE because there is no visible evidence of surgery on the back of their head. There’s nothing to suture, and the small dot wounds are not detectable a few days after surgery”.

• Mohebi also specializes in eyebrow transplants for both men and women.
• As testament to his skills, he also repairs bad or “pluggy” transplants, performed by other doctors. “We do several repair hair transplant surgeries a month,” he says.

Mohebi spends an hour with each new patient and does a microscopic evaluation of the scalp and a miniaturization study of the hair to predict future hair loss. “That way we’re not limited to the obviously bald areas, but we can transplant hair to where the patient may lose hair in the future. With the technology we have now, there’s no reason for anyone to experience hair loss.”

As a fellowship-trained hair-transplant surgeon, Dr. Mohebi continues research the latest high-transplant techniques and his writings have been presented and published in both national and international medical-society publications.

The article continues with discussing the published research on the psychology of hair transplant in men, which was finished last year: Dr. Mohebi’s latest article was the cover story for Hair Transplant Forum International, considered the most important journal in the field of hair restoration, on The Psychology of Hair Transplants. From research in Europe, we know that people with hair loss are prone to anxiety, depression and other psychological problems; we tried to see if we can reverse that with hair restoration surgery.

He evaluated 200 patients after surgery in eight criteria, and saw improvements with FUT in terms of happiness, youthfulness, energy levels, self-esteem and self confidence, future outlook and impact on their career and sex life. The results were amazing and improvements in all eight criteria were statistically significant. The authors, Dr. Mohebi and Dr. Rassman concluded that using the new techniques of hair restoration patient can drastically improve all of the psycho-social impacts of hair loss.

The reporter then set aside US Hair restoration from many other hair transplant clinics by several factors by referring to Dr. Mohebi’s comments on following the latest standards of hair restoration surgery and the fact that things have changed significantly recently in the field of hair restoration. What was done five years ago is not acceptable today. We have the most experienced technicians; and everything is done under a microscope to get the highest yield of hair.

Then there’s the customer service. “The day of the hair transplant procedure is a big day for patients,” Mohebi said, “often six to eight hours. Patients are usually amazed at how smooth and pleasant the day is.

Patients are given mild to moderate sedation and numbing medication for the donor and recipient area. Once the scalp is numb the strip of skin is removed and the wound is closed. The next step is to prepare hair grafts under microscope. While grafts are being made by experienced technicians of US Hair Restoration, Dr. Mohebi is designing the hair line and makes the sites according to the natural direction and distribution of hairs.

Since the newly placed follicles are so fragile, patients return the next day to get their hair washed professionally, given special shampoo and taught how to take care of their hair at home. “After five days, no special care is needed,” Mohebi said.

Ten days after the surgery, patients return to have the donor site checked and staples removed for those who had them. Hair starts growing after three months, and is long enough to style and comb after ten to twelve months. The third follow up is at 10 months after the procedure.

Severe baldness may require more than one surgery, usually spaced at least six months apart. “With megasession hair transplants we can do 4,000 grafts in one day. That significant number is a help to patients with a high class of baldness. We can get a higher stage of restoration with fewer sessions of transplants.”

Continuing to pioneer in the field, Dr. Mohebi is the inventor of the Laxometer, a device to measure the laxity or mobility of the scalp. Laxity of the scalp is key in determining the size of the donor strip so that enough can be removed for bigger cases, and the wound can be closed without too much tension and the scaring will be minimal.

To help people stay abreast of all that’s happening the field of hair restoration, and to answer questions (he’s heard from Europe and China) Dr. Mohebi maintains a hair restoration blog, ushairrestoration.com/blog.

Mega session hair transplant surgery has been around for almost a decade since Dr. Rassman and others started doing bigger and bigger sessions. Before 1993 all could be done was less than 1000 and occasionally 1500 grafts per each session. Using newer techniques and larger team of experienced technicians, we at US Hair Restoration are currently performing large sessions on a regular basis.

Not all physician teams are equal. If a doctor routinely performs sessions in over 2500 graft size, then it would be safe to assume that this doctor has mastered the skills required for large session. Unfortunately, not all doctors have either the teams or the skills to accomplish the feat on a routine basis. Limiting the size of the session to under 2000 grafts, it may take more surgical sessions to accomplish the same goal as when twice the number is transplanted.

Many factors should come together for a megasession hair transplant surgery. First, the surgical team must be trained in doing large sessions with fast, efficient cutting and placing. The following points must be available for the surgery to be successful. The sessions should not take more than eight to ten hours, for more than that, the grafts that are out of the body awaiting placement produces reduced graft growth. Hair transplant surgeon should keep a larger team of technicians to help reducing the time of surgery.

The surgeon must know the nuances of prolonged anesthesia without increasing the risks to the patient. The patient’s scalp laxity must be very loose so that a wide strip can be taken safely (often these strips measure greater than 2cm in width and 22cm in length). The patient’s density must be high (50% higher than normal densities). Large sessions might carry increased risk of swelling and redness after surgery, but overall are not more risky than smaller sessions, but the above criteria must be bet or the yield would not be there. At US Hair Restoration, we offer megasessions to patients with extensive baldness with good donor quality with excellent results.
