Some day, perhaps in the distant future, baldness may become a curable aliment. Scientists are currently researching gene therapies to alter a person's genetic vulnerability to hair loss. However, the actual implementation of such hair loss treatments may be decades away.

In the near future, drug treatments which inhibit the balding process seem more promising. The hair loss drug Propecia (finasteride) has been proven successful in slowing and/or stopping hair loss by blocking the conversion of testosterone into dihydrotestosterone (DHT) in the scalp.

Another promising drug that inhibits the development of hair loss causing DHT hormones is Dutasteride.

Like Propecia, it also inhibits the creation of DHT. And based on preliminary clinical studies, dutasteride promises to be even more successful than Propecia in inhibiting the production of DHT.

In addition, Dutasteride inhibits the activities of two types of 5-alpha-reductase enzymes. In contrast, Propecia (Finasteride) only inhibits one type. Dutasteride has been shown to decrease levels of DHT by 90% after only two weeks, making it a more powerful and faster-acting weapon against hair loss than Propecia (Finasteride).

Dutasteride is not yet FDA approved for the treatment of hair loss. However, it is being marketed as Avodart by GlaxoSmithKline as a hair loss treatment. Some hair restoration physicians also prescribe it for the treatment of hair loss. Like Propecia, Avodart is not safe for women and children.

In time, perhaps even more effective hair loss drugs will be developed to inhibit the hair loss process.

Future Hair Transplants - an endless supply of bald resistant donor hairs?

The amount of hair you can transplant is ultimately limited by the amount of hair follicles you can safely relocate from the bald resistant donor area at the back and sides of your head.

Some day it may be possible for physicians to create multiple hair follicles from one original follicle. This process typically called "hair cloning" or more correctly "Hair Multiplication" is currently being investigated by several research scientists and hair restoration physicians.

If and when this process is successfully developed patients would no longer be limited by the finite amount of bald resistant hairs that can be relocated from their donor area. Hair multiplication would result in a virtually limitless supply of hair available for hair transplantation.

This would be especially good news for men or women with extensive baldness and a very limited supply of donor hair. Even those with extensive baldness would theoretically be able achieve thick full heads of hair.

However, experts believe that we are at least ten years away from hair multiplication being available, if even then.

For most men and women, hair loss can be effectively halted or even reversed with current hair loss treatments. But the future holds the promise of even more effective treatments and perhaps some day even a "hair loss cure".

Follicular unit extraction is a minimally invasive procedure for performing follicular unit hair transplantation. However, unlike the predominant follicular unit transplant procedure, in which a strip of donor tissue is removed and dissected under magnification, the FUE procedure uses a small punch to extract each follicular unit one by one.

Both the strip excision and FUE procedures create 1, 2, 3, and 4 hair follicular unit grafts that are then transplanted into the balding area in the same manner. The primary difference between these two procedures is the technique used to harvest the follicular unit grafts.

Comparing the Strip Excision procedure to the Extraction (FUE) procedure

The common strip excision method of performing follicular unit hair transplantation involves surgically excising a thin horizontal strip of bald resistant skin from the donor area.

Strip Excision Procedure

This donor area is then sutured together. These sutures (either stitches or staples) are then typically removed about ten days after surgery. Some physicians use dissolvable sutures so that no removal is needed.

Once this linear incision is fully healed the patient is left with a thin horizontal scar in the back of the head. This scar is typically hard to detect since the surrounding hair conceals it, even when the hair is cut short.

How the FUE Procedure is performed

With the Follicular Unit Extraction or FUE procedure 1, 2, 3, and 4 hair follicular unit grafts are carefully extracted one at a time using a tiny punch of one millimeter or less. Often the surgeon requires the patient to buzz cut a portion of their donor area so that they are able to see the patient’s scalp.

The follicular units are extracted

The follicular units are extracted by placing the punch around a single follicular unit and cutting a small circle through the skin around that follicular unit. The follicular unit is then gently pulled up and away from the loose tissue underneath the skin.

The small hole left behind after the follicle is extracted then heals over the following week. Normally this small round incision contracts as it heals making the resulting round scar smaller than the size of the 1mm punch that made the incision. The FUE patient ultimately ends up with hundreds of small round white scars, which are normally not detectable once the patient’s hair grows out.View a video of an actual FUE surgery.

To Extract or to Excise, that is the question.

Advocates for the relatively new FUE procedure claim that this procedure produces less noticeable scarring and no tightness or numbness in the donor area since no donor tissue has been pulled together and sutured. Many patients and physicians find the claim that FUE produces less visible scarring to be debatable.

Some physicians and patients also have concerns about the relatively new FUE procedure, such as the lack of formal studies regarding the percentage of follicles that may or may not be transected during the sight unseen extraction process.

In addition, since the physician must personally extract all follicles, one by one, the FUE procedure is very physician dependent and thus very expensive. The FUE procedure also requires considerably more time in surgery to move a given amount of hair to the balding area.

The standard strip excision procedure has the advantage of utilizing a collaborative team to carefully create the grafts once the donor tissue is removed in a strip. This collaborative approach enables a well trained staff to do sessions of 2,000 to 3,000 all follicular unit grafts in a single day. This team approach enables a patient to get a much larger number of grafts/hairs in one sitting at a much lower cost per hair than with the FUE procedure.

However, some believe that despite being relatively costly the FUE procedure may be appropriate for patients who have very limited elasticity in their donor area or who only need a small number of grafts.
