BACKGROUND: Little is known concerning hair diameter variation within the safe donor area for hair transplantation surgery. Thicker or thinner hair may be needed, depending on the recipient area, hairline design, and the purpose of surgery. METHODS: Twenty-seven patients (7 men and 20 women; mean age, 28 years; range, 20–47 years) were included in this study. The midoccipital point was used as the reference point on the horizontal plane at the upper border of the helical rim. The target area width was 15 cm (7.5 cm to the right and left of the reference point) and the height was 8 cm (2 cm above and 6 cm below the reference point). The study area was divided horizontally into 3 5-cm sections (A, B, C) and vertically into 4 2-cm sections (1–4), creating a total of 12 zones. Ten anagen hairs were randomly obtained from each zone and their diameters were measured. RESULTS: Hair diameter in the 4 vertical sections varied significantly, gradually decreasing from sections 1 (superior) to 4 (inferior) in all 3 horizontal sections (A, B, and C). CONCLUSIONS: Our results suggest that sections 1 and 2 of the occipital safe donor area would be useful for obtaining thicker hair, such as in procedures to treat male- and female-pattern hair loss, whereas hair from zones 3 and 4 could be useful for transplantation surgery requiring thinner hair, such as eyebrows, eyelashes, and female hairline correction. Our results may be clinically valuable for planning hair transplant surgery and choosing the optimal donor region.

BACKGROUND: Frontal fibrosing alopecia (FFA), typically observed in elderly women, is characterized by a band of frontal or frontoparietal hair recession with scarring and a marked decrease, or a complete loss of the eyebrows. OBJECTIVE: To describe the clinical and histopathological features, and response to treatment of FFA in Korean patients. METHODS: A total of 7 female patients, diagnosed as FFA at our department from 2003 through 2006, were evaluated. RESULTS: All patients presented with a band of symmetric recession of the frontoparietal hairline. Four patients (57.1%) had symmetric loss of lateral eyebrows. Two patients (28.6%) were premenopausal. The histologic features were similar in all patients with a reduction of the number of hair follicles, and a perifollicular lymphocytic infiltration with lamellar fibrosis limited to the upper portions of the follicles. The progression of the condition stopped in all patients after topical steroid treatment. CONCLUSION: Cases of FFA affected in premenopausal female patients drove us to consider that this condition is not exclusive to postmenopausal females. To make a diagnosis of FFA, we should remind ourselves of the typical clinical and pathologic features. Further studies are necessary to confirm the possible role of treatment in FFA and stop the progression in the early stages of FFA.

We report a sporadic case of hypotrichosis simplex of the scalp, a rare genotrichosis, characterized by sparse or absent scalp hair with no structural defect of the hair shaft, in the absence of other ectodermal or systemic abnormalities. A 9-year-old girl had normal-looking hair at birth but subsequently lost the hair on her scalp after she turned 3 years of age. However, her eyebrows and eyelashes remained normal. Skin, nails and teeth were also normal except for malocclusion. No other family member had a similar hair defect. Hair shaft examination did not reveal any structural abnormalities. Microscopic examination of a scalp biopsy specimen showed a reduced number of hair follicles.

There are several methods for restoring the temporal peaks. The most important point is the variable density and angulation of the hair, which ultimately give a soft and natural look. The current technique produces zones of variable density and helps to restore naturalness.

A 26-year-old Korean woman had a 5 month history of pruritic, keratotic papules on the scalp, trunk, and pubic area, which were accompanied by diffuse hair loss from the scalp, eyebrows and pubic area. She also had flat-topped violaceous papules on the scalp and pubic area, and white lace-like striae on the oral mucous and hard palate. Histopathologic study of the progressive stages of the disease revealed dilated follicles filled with horny material, hyperkeratosis, hypergranulosis and hydropic degeneration of the basal cell layer. Throughout the entire subepidermal region, there was an intense bandlike infiltration of mononuclear cells, which were most prominent at the lower pole of the hair follicles. The late stage of the disorder showed atrophy of the epidermis and atrophy of the hair follicles with fibrotic tracts, and mild mononuclear infiltrate at the sites of the former hair follicles. This is the first recorded case, to the best of cur knowledge, in Korea.
