Treating Female Pattern Baldness and Repairing Distortion and Scarring from Prior Cosmetic Surgery

In women, the role of  transplant hair is less common than men and often the losing of hair is very distressing. While over 95% of all hair transplant procedures are performed on men, women are candidates and undergo hair transplant procedures for the treatment of several conditions such as inherited female pattern balding, low thyroid or iron levels, hormonal imbalances such as elevated testosterone, binge dieting, and pregnancy. Another cause of hair loss in women is the distortion of hair growth and scarring as a result of prior facial plastic surgery. Most of these conditions however are treatable, giving women new options with different techniques than used in men that when performed correctly, consistently achieve excellent results and minimize complications.

Female pattern baldness occurs along several different patterns, the most common consisting of diffuse thinning along the top and upper sides and back of the head, often sparing the frontal hairline. This classic form of FPB can be divided into stages according to the Ludwig classification scheme ranging from mild hair loss to extensive hair loss. In patients with stage 1 (mild hair loss) and most cases of stage 2 classic FPB, as well as those with less common patterns, there is usually sufficient hair density in the donor region for effective transplantation at least by restoring density to the thinner areas. Women with stage 3 (extensive hair loss) are usually advised not to undergo the procedure.

The other, and most common, condition in women effectively treated is the alopecic scarring and hairline distortion associated with prior plastic surgery. The most common type is the loss of the sideburns caused by rhytidectomy incisions that extend superiorly from the upper aspect of the ear. The hairline distortion often produced by the incision can cause significant hair styling difficulties. Another type of distortion is the excessive elevation of the frontal hairline associated with brow-lift incisions in patients with pre-existing high foreheads. Alopecic scarring most commonly occurs along the frontal and temporal incisions of browlifts and the occipital incisions of hysterectomy. The goal of hair transplantation in these cases is to restore hair growth in the scarred and thinned-out areas and to recreate the normal anatomy of the temporal tufts and the frontal and temporal hairline.

Treatment of Female Pattern Baldness

When performing hair transplantation on women with FPB, the limited supply of donor hairs limits the amount of coverage that can be achieved. While most patients would like to have all thinning areas treated, the hairs should be transplanted into those areas where they will provide the maximum benefit for the patient. Most commonly, these beneficial areas are the mid-top of the scalp posterior to and sometimes up to the frontal hairline and along where the hair is parted. It is crucial that the donor region is assessed prior to planning a procedure to make sure that enough hair is present to make the procedure worthwhile and effective. For the best results, the procedure should maximize the number of hairs transplanted while minimizing the trauma to the existing hairs, usually best accomplished by transplanting grafts containing 3 to 5 hairs, except along the hairline where smaller grafts of 1 or 2 hairs are placed to assure natural appearance.

In the typical case, 600 to 800 grafts (or about 2500 hairs) are transplanted, placed atraumatically into the incisions. Careful handling, along with keeping them moist, minimizes damages and ensures good growth. To minimize the loss of hairs due to shock and to accelerate the regrowth of the transplanted hairs, 1 week after the procedure, patients should restart the daily application of 2% minoxidil (usually they will have already used the minoxidil in the weeks leading up to the procedure to help stimulate additional hair growth, stopping its use 3 days prior to reduce the risk of significant bleeding). With this regimen, the hairs can be expected to start growing at 2.5 months, rather than the typical 4 months.
