Incidence of female androgenetic alopecia (female pattern alopecia).

BACKGROUND: Female pattern alopecia seems to be increasing. A recent article suggests that female androgenetic alopecia may not be androgen dependent and is a different entity than male androgenetic alopecia. OBJECTIVE: To determine the incidence at different ages of female androgenetic alopecia in 1000 Caucasian women 20 years of age and older. METHODS: A total of 1006 Caucasian women were examined for the presence of female androgenetic alopecia. CONCLUSION: Female androgenetic alopecia is quite common beginning in the late 20s and reaching its peak after 50 years of age.

Female androgenetic alopecia: a separate entity.

BACKGROUND: It has always been assumed that female AGA represents the female counter part to male AGA. OBJECTIVE: To present arguments illustrating that these are entirely different entities. METHOD: Four well-known facts about both entities that would indicate they are separate are cited. Family pedigree filled with female AGA and minimal male AGA is presented and a reference to a female with no curculating androgens and typical female AGA is cited. RESULTS AND CONCLUSION: Based on evidence presented it is concluded these are two entirely different diseases.

Standardizing the classification and description of follicular unit transplantation and mini-micrografting techniques. The American Society for Dermatologic Surgery, Inc.

Previous attempts at classifying small graft transplants have focused mainly upon graft size and have not taken into consideration other technical factors involved in graft production that may influence the outcome of the surgery. The proposed classification attempts to consider these factors by including various technical aspects of harvesting, dissection, and placement, all of which impact the quality and quantity of the small grafts used in the procedure. By standardizing the nomenclature, as well as the description of the other factors involved in the surgery, communication between physicians and patients may be facilitated. In addition, different procedures may be more accurately studied and compared.

Hairline design and placement.

A simple, straight forward, almost mechanical method of drawing the hairline is presented. It is amazing to see how this method, when followed closely, consistently produces a natural, aesthetically pleasing result on all sizes and shapes of heads. It is recognized by the authors that there are a lot of individual variations among hair transplant surgeons and most will be very attractive and quite natural. However, we believe that the following description will provide a good starting point in designing hairlines, and if the basic points are followed, unnatural hairlines will be avoided.

Hair transplant surgery: innovative designs.

Two new designs for hair transplant surgery are presented. Both designs are safer and will provide a more natural appearance in some patients than standard designs. The advantages are listed for both.

Single row donor site harvesting.

Preservation and care of the donor area is as important as designing and planning the recipient area. Conservation of the donor areas is accomplished by cutting grafts in a single row, keeping the rows at least 2.0 cm apart, and by careful, delicate suturing of the donor area.

Scalp reduction in the treatment of androgenic alopecia.

Scalp reductions represent an advance in the surgical treatment of male-pattern baldness. The initial enthusiasm that is shared by both the patient and the surgeon should be tempered by the knowledge that there will be some stretch-back and distortion of the bald area and that the scar may present a problem with styling.

Micrografts and minigrafts for refining grafted hairlines.

Micrografts and minigrafts comprise the newest and most exciting recent refinement in hair replacement surgery. They overcome the tufted and abrupt hairlines common to punch-graft surgery. Micrografts are used for softening and feathering the hairline, and minigrafts are best used for thickening the hairline.

Complications of scalp reductions.

Early problems with central sagittal scalp reductions are primarily medical and surgical. As they resolve with surgical experience, the cosmetic problems become more apparent. These problems and complications are outlined along with suggestions for prevention and correction.

Predicting hair growth for hair transplantations.

Even with proper surgical technique and no complications, some individuals do not seem to grow transplanted hair as well as others. In order to see if it is possible to identify such individuals prior to surgery and the reasons for their peculiarity, 130 consecutively new patients were stated for study and 100 were eventually available for study with special reference to twelve likely factors. Of the twelve, five, namely, looseness of scalp, thickness of scalp, density of transplanted hair, quality of grafts, and scarring, were found to have predictive value in foretelling eventual quantity of hair growth.

Whisker hair--an update.

Whisker hair is short, curly, dark hair that grows anterior to, above, and behind the ears in young persons who eventually develop severe androgenic alopecia. It is called whisker hair by lay persons because of its proximity and similarity to beard hair. Presented herein are some previously reported cases of whisker hair and a hypothesis on its eventual fate.

Infection with hair transplant surgery.

The problem of infection during hair transplant surgery in one dermatologist's office is described herein. Careful epidemiologic investigation identified the causative organism and its source, and the infection was effectively controlled by the use of "semi-sterile" technique. Infection may be more common than generally suspected and it should be considered as a possible cause of otherwise unexplained disappointing results as reflected by decreased numbers of viable hairs per graft.
