How To Assess Scalp Laxity Before Hair Transplant Surgery

Sunday, November 9th, 2008

Laxometer for hair transplantationThis is another article from Dr. Mohebi that is recently published on the cover of the Hair Transplant Forum International: the journal of the International Society of Hair Restoration Surgery.

The laxometer was invented by Dr. Parsa Mohebi two years ago. Laxometer is a device that is used to measure the mobility of scalp skin, which is a crucial piece of information for hair transplant surgeons before hair restoration surgery with strip method.

Evaluation of scalp laxity prior to hair transplant procedures has been a clinical subjective evaluation that varies with each surgeon and each visit. Hair transplant surgeons have been traditionally assessing the laxity of the scalp with manual palpation of the donor area and by moving the scalp horizontally or vertically, estimating the scalp movement against the occipital bone.

Measurements have been recorded with subjective term such as very loose, moderately loose, average, moderately tight, and severely tight. With the use of the laxometer we are provided a more precise metric for use in hair transplant surgery.  You can read the full article “How to assess scalp laxity” on US Hair Restoration Website.

Beverly Hills Hair Transplant

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 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.

Hair Transplant Scar

Thursday, April 10th, 2008

Hi Doctor,

My son has had a hair transplant years ago with old techniques and he has bad hair transplant scar now. He now wants to shave his head, but the scar of hair transplant on the back of his head may become exposed. Do you perform hair transplant scar repair or do you recommend any procedure that can help with hair transplant donor scar coverage?

Hair Transplant Scar

Answer:

Hair transplant with strip technique can cause a linear scar that could be visible on the back of head if the patient wants to shave his/her head. A hair transplant scar is not limited to a bad hair transplant technique and it might have to do with one’s personal healing process too (some people are generally better healers compared to the others).

The good news is that we have methods to minimize the size of the scars nowadays and if you have bad hair transplant scars from bad transplants in the past, there are several new methods that can help improving the appearance of the donor scar. A hair transplant scar could be improved by repair of linear widened scars with different methods that we perform at our Los Angeles office of US Hair Restoration. Dr. Mohebi is the inventor of the axometer, a device that measure the laxity of the scalp precisely before hair transplant surgeries. Good measurement of the scalp laxity is one of the best ways to minimize development of donor wound complications and widening of donor scar and the Laxometer is the device to do these measurements.

One method is through simply excising the scar. Excision of the donor scar may be helpful for some donor scars. After removing the scar, hair transplant surgeon can close the skin with the trichophytic closure method in which a small wedge on one or both sides of the skin edge is removed and the skin is closed primarily. Trichophytic closure allows some hair follicles to grow new hair into the final scar. Presence of hair helps making the hair transplant scar become invisible.

Hair transplant donor scar coverage could also be performed by transplanting hair into the scar. Hair could be harvested from other areas using FUE or mini-strip techniques. Again, presence of the hair inside scarred area could trick the discriminating eye and the scar would become less detectable. Patients may need more than one hair transplant procedure into the donor scar for minimizing the difference between the densities of hair in scar and surrounding areas.

The last method that could be used to camouflage the linear scar is by tattooing the scar. People who plan to keep the hair very short can easily tattoo the scar with the figures of short hairs so it seems that there are some hairs present in the scar area, which can help minimizing the visibility of the scar.

Laxometer and Hair Transplant Surgery

What is A Laxometer?

A Laxometer is an innovative device that measures scalp characteristics, and is mainly used in hair restoration surgery. A Laxometer can help determine the laxity (looseness) of the scalp using the strip technique, which gives hair transplant physicians valuable information before a hair transplant surgery. The Laxometer was first presented at the 15th Annual Meeting of the International Society of Hair Restoration Surgery in Las Vegas.

The Laxometer was invented by Dr. Parsa Mohebi and introduced as the first tool that could objectively measure the laxity of scalp in hair transplant patients.

The Laxity of the scalp is a critical factor in evaluating patients before hair transplant a procedure, especially for those patients who have a high demand for hair and scarce resources. The Laxometer can reduce the risk of donor complications. Donor complications happen when a surgeon cannot easily close the donor wound after removing the strip of skin from the donor area.

We have defined two different types of

Laxometer types:
1. A Clinical Laxometer can be used during a clinic visit. Clinical Laxometers are non-invasive and easy to use in assessing patients’ scalp laxity in pre-op evaluation or following the improvement of scalp laxity after a period of scalp exercise.

2. An Intra-operative Laxometer is more précise and is used during hair transplant surgery right before removing the strip. Having a more précise measurement of scalp laxity can significantly reduce the chance of removing too much skin, which can make closure of the donor wound difficult.

Physical Activity Limitations After Hair Transplant

Saturday, January 12th, 2008

Question:

I am a 40 year old man. I had a hair transplant 15 days ago and have my sutured removed 5 days ago. I am generally very active, but my doctor said that I can not exercise intensively for first 3 months after surgery. When do you usually say is safe to resume heavy exercise.

Thanks A lot!!

Answer:

Dealing with daily activity and sports after hair transplant surgery is a concern for many patients who are physically active and want to get back to their normal routine as soon as possible. There are two areas of concern after a hair transplant surgery. First, you may lose newly implanted grafts when doing contact exercise like wrestling. This can only be problematic within the first 4 days after surgery. Research has shown that after this period the hair graft is completely healed and infused in surrounding skin. Usually evenpulling the hair after this period of time doesn’t have an adverse effect. The follicle stays in place and is capable of making a new mature hair.

The second concern is with the donor area, which is primarily closed by sutures or staples. Using Laxometer can help up to close donor wound with not much tension on the wound edges. The healing of the donor incision follows the general wound healing rules. The process of healing starts from the moment the wound is closed. The wound heals primarily within a few days from the time of hair transplant and any vigorous activity should be avoided within the first two weeks. After two weeks, the wound is practically healed, but the strength of this newly healed wound is nowhere close to normal skin. The wound needs a few months to get back to its final strength. However, regular aerobic exercise is not contraindicated even the day after surgery.The activities that you should be avoiding are: Anything that increases the tension between the edges of the healingwound in the donor area, such as weight lifting and other exercises which involve intense bending of the neck. You should wait at least 6 months for this type of exercise in order to prevent opening of the wound or widening of the final scar.
