Over the past several years surgeons have used various techniques to perform follicular unit hair transplantation. One such technique is the Lateral Slit Technique, also known as Coronal or Perpendicular Grafting. This technique’s name is derived from the angle and direction in which the graft incisions are made.

While there are other techniques for performing densely packed and highly refined follicular unit transplantation, the lateral slit technique offers a high degree of control over the angle and direction in which the transplanted hairs will ultimately grow.

The lateral slit technique has been used both intuitively and systematically for years by hair restoration physicians. However, it has recently gained popularity as a systematic and precise way of performing follicular unit hair transplantation.

How our member physicians use the Lateral Slit Technique.

Many of our physician members use the Lateral Slit Technique exclusively or in combination with other techniques for creating graft incisions. The lateral slit technique enables a surgeon to create graft incisions at varying angles (ranging from 10 to 90 degrees to the scalp), including very acute angles that will make the transplanted hair grow out lying flatter to the scalp. The ability to create incisions at very acute angles is particularly useful in areas such as the front temples and sides where the hair normally grows out lying flat on the scalp.

The graft incision determines the direction of the hair growth

The lateral slit technique also helps enable a surgeon to determine the direction of the graft incisions. This then determines the ultimate direction of the transplanted hairs growth. Thus a surgeon can use this technique to control and vary both the direction and angle at which the transplanted hair will grow in order to mimic the subtle changes in hair direction that occur naturally.

Each graft incision is created by analyzing the neighboring hair so the surgeon can reproduce the correct hair pattern. As a result, as each transplanted hair emerges from the scalp it will grow and lay in a similar direction as its neighboring non-transplanted hairs.

Lateral slits can enable denser packing of grafts

Lateral slit incisions also tend to be more parallel to the scalp and thus more superficial and less invasive to the scalp’s underlying vascular structure. This parallel alignment also enables a physician to place more grafts per square centimeter with out the grafts compressing or popping up since the pressure exerted on the grafts does not push them upward from the scalp.

Using blades cut to the size of the grafts

Some of our members use custom blade cutters to create tiny blades to make incisions that match the size and depth of each follicular unit graft being transplanted. This enables a surgeon to safely dense pack more grafts into a given area during a surgical session. Healing time is also more rapid, with minimal scarring.

Typically most clinic’s blades range from 1.5mm to 2mm in size. However, by using the custom blade cutter our physicians can create blades as small as .7mm for a single hair graft and .9mm for a multi hair graft.

In addition, the blades created by the custom cutter are squared off to match the shape of the bulb end of a hair follicle. Non custom cut blades are typically spear pointed which requires them to be inserted deeper thus causing more trauma to the scalps vascular structure.

The ability to control the depth of the incision each blade makes is also critical. Each blade is placed in a blade holder that is set to not allow the blade to go any deeper than required for the graft to being placed in the incision. This minimizes unnecessary trauma to the deep vasculature of the scalp, thus enabling close tight incisions, minimal tissue swelling, and quick healing that leaves no visible scaring, pitting, or cobble stoning of the scalp.

Placing grafts to maximize their aesthetic result and coverage

The plane and direction in which each follicular unit graft is placed on the scalp can also impact the ultimate appearance of density that can be produced with a given number of grafts. This is because hairs within a follicular unit are typically next to each other inline.

Therefore by arranging each multiple hair graft on the scalp in a linear fashion to the line of sight, each follicular unit will provide the maximum appearance of fullness and scalp coverage. This also mimics how hair is normally aligned on the scalp.

One product you used to see quite often in advertising is Avacor. According to Response magazine, Avacor was the third best selling product on the Internet in April, 2002. Avacor was originally manufactured by Global Vision Products. After being taken over by new management, it is now being manufactured by Avacor Products LLC.

Like most products that advertise 'Stop Hair Loss and Regrow Hair!', Avacor contains the only FDA approved topical drug minoxidil. Avacor, like other products with similar claims, mixes FDA approved drugs in their generic form with other ingredients in a multiple regimen of products like shampoo, lotion and vitamins.

Avacor historically cost approximately $239 for a two to three month supply and over $1000 for a year’s worth.  New prices are much more reasonable which range from $180 for a 3 month supply to $400 for a year’s supply of the men’s and women’s formula. Note that the ingredients in Avacor can be bought over the counter at your local store at a fraction of the cost for which they are sold in Avacor. However, they do offer 24/7 customer service and a 90 day money back guarantee.

Marketing Practices

Avacor, like other products with similar claims, has taken a lot of slack over the years for their controversial marketing tactics. Avacor has a checkered past and has previously been the focus of lawsuits and investigative reporting by major media like ABC news. Recently however, new management has taken over and claims they are very serious about selling quality products at more reasonable prices, without the hype and controversial marketing strategies. In looking at their website, while Avacor still uses slick marketing language to promote their products, the vast majority of their claims are much more realistic.

Avacor includes 3 distinct products that claim to provide “total hair care”. This includes a 'Scalp Detoxifying Shampoo', a 'Physicians Topical Formulation' and finally a 'Nutricap'. Avacor's Nutricap ingredients consist mainly of common herbs like saw palmetto, gingko biloba, keratin, resveratrol, and bilberry. While conjectured to inhibit the production of DHT, none of these ingredients are FDA approved or proven to stop hair loss. Avacor’s Physician’s Topical Formulation however, does contain 5% of the FDA approved hair regrowth agent minoxidil.

Other than minoxidil, no other ingredient is proven to regrow hair. A number of studies have been done that suggest saw palmetto inhibits the production of DHT, like Propecia. But, unlike Propecia, it has never been proven to stop or reverse hair loss.

Avacor Products

Avacor admits on their website that the only product proven to regrow hair is the Avacor Physician’s formulation which includes the FDA approved ingredient minoxidil (5% for men and 2% for women). The other products claim to provide hair with the essential nutrients for healthy hair growth but are careful not to claim to prevent the progression of male or female pattern baldness (androgenic alopecia). Perhaps this is why the Avacor Physician’s formulation can now be purchased separately. Costs of the Physician’s Formulation are still, but only a little more expensive than Rogaine topical hair loss treatment, one of the first and most popular topical minoxidil products.

The Avacor Study

At this time, Avacor’s proof comes in the form of the FDA approved study showing that minoxidil can stop and reverse hair loss.  No other study is provided with their product.  Their website also is much more realistic as to what their product line can accomplish for hair loss suffering consumers.

Confidence in Products and Services

Before you consider spending hundreds of dollars for any product or service, do a review. Legitimate products will have legitimate studies and have been reviewed on many quality websites. Doctors with real talent and satisfied patients will be able to show you dozens of photos and allow you to talk with past patients. Proven physicians will make available their resumes along with their formal education and associations they belong to.

It is always best to review a product or doctor for information on their background before you make a decision for something as important as hair loss and hair restoration.

Conclusion

At the very least, the Avacor Physician’s formulation will be as effective as the Rogaine liquid formula or generic minoxidil. However, to date, both Rogaine and generic minoxidil are more cost effective than Avacor.  The nutricap, shampoo, conditioner and other products may promote healthy hair and provide it with volume, but make no claims of stopping hair loss or regrowing hair.

We believe that patients have a right to full disclosure and a complete understanding of exactly what hair restoration surgery involves.

This step by step presentation shows how today’s state of the art follicular unit hair transplant procedure is typically performed.

Patient is prepared for surgery

During surgery hair follicles from the back of the head that are genetically resistant to going bald will be removed and relocated (transplanted) to the balding areas.

Donor area is trimmed

Prior to surgery, the hair in donor area that will be surgically removed is trimmed.

Donor area is prepared for surgery

Once the donor area has been prepared it is given local anesthesia.

Donor tissue is removed

The donor tissue containing the bald resistant hair follicles is then surgically removed.

Donor area is sutured

The donor tissue containing the bald resistant hair follicles is then surgically removed.

Hair combed over sutures

When patient’s hair is combed over the donor area the sutures are not visible. These sutures are typically removed approximately ten days after surgery.

Donor tissue is trimmed into follicular unit grafts

Surgical technicians then use microscopes to view the donor tissue in order to dissect and prepare follicular units hair grafts.

Bald recipient area is prepared

After being given local anesthesia, the balding recipient area is ready for surgery. No trimming or shaving of hair is needed in the top recipient area.

Incisions are made in the balding areas

Tiny incisions are made in the recipient areas in irregular patterns that mimic nature. The follicular unit grafts will then be placed carefully into these tiny incisions.

Grafts are placed into the incisions

Follicular unit grafts are gently placed into the recipient incisions.

Grafts are placed in varying densities

Typically the smallest one and two hair grafts are placed in the very front of the hairline, with three and four hair grafts placed behind them.

Patient immediately following surgery

Following surgery a patient will have hundreds of tiny incisions with short hair stubble showing from the new grafts.

Close up of recipient area after surgery

The tiny graft incisions heal rapidly. The redness and scabbing in the recipient area normally clears up within about one week.

Our physician members perform a very refined hair transplant procedure called "Follicular Unit Hair Transplantation". Today there are two methods for doing this procedure. They differ only in the methods used to harvest and prepare the grafts.
