This study is intended to look into the effects of wig wearing on scalp disorders in female patients with cancer. To achieve this, a survey was empirically carried out to female patients with cancer. The findings are as follows. The effect of wig wearing for hair loss on scalp itching in female patients with cancer showed that larger inconvenient factors did not cause the itch when wearing wig. And the adhesion, perspiration and psychological shrinking of wig wearing did not directly spark the scalp itch. The effect of wig wearing for hair loss on scalp trouble in female patients with cancer showed that higher inconvenient status and psychological shrinking significantly caused scalp trouble when removing wig, while the adhesion and perspiration did not directly correlated with scalp trouble when removing wig. As for the findings, it suggests that the simple adhesive status and perspiration do not just cause scalp disorders in that wig wearing for hair loss causes the scalp itch and trouble in female patients with cancer.

The relationship between copper content in scalp hair and mental retardation was investigated. Samples of scalp hair were collected from 297 mentally retarded children who were students in one of two schools providing special educational services, one, consisted of children living in an orphan home, the other, children living with parents. For comparison, 117 scalp hair samples were collected from the children who had got average or above average academic achivement in a regular elementary school. Hair samples were taken from the nape of the neck and the copper content was determined by an atomic absorption spectrophotometer (IL 551). There was no statistically significant difference in scalp copper levels across different age groups except female orphan group, but no trend or correlation between copper conents and age was found. The hair copper contents of the mentally retarded children groups were significantly lower than that of control groups. But there was no dose-response relationship between degree of mental retardation and hair copper level. The hair copper contents of the group accompanied by Down's syndrome and unknown group were significantly lower than that of control group in both sex, and in the case of accompanied by epilepsy or autism, lower than control group in male. Although the results of this study show no evidence that mental retardation has owed to copper deficiency, the possibility of copper deficiciency in their fetal or infant age could not be ruled out. Thus further study is needed to determine whether mental retardation could be attributed to copper deficiency, through the examinations about their living environments, dietary pattern, eating habit and the impact of copper deficiency on brain development.

The average value of total mercury contents in scalp hair of Korean male was found to be 1.66+1.10 ppm (S.D.) and that of methylmercury was 1.02+0.72 ppm (61.0% of the total mercury). In case of total mercury contents of female was 1.06+0.46 ppm and that of methylmercury was 0.51+0.27 ppm (48.4% of total mercury level). When compared with data reported by Japanese, the levels were about half. The levels of mercury in scalp hair of male subjects were significantly different with their occupations, but in case of female, the variation was not so much.

Identifying tumors or wounds on the scalp is difficult because hair blocks the vision during surgery and suturing. In the meantime, we have commonly used hairpins to hold the hair for a clearer view; however, we would like to suggest a new method, a "hair-fixing sheet," consisting of hook-like surface. We applied the two methods, hair-fixing sheets and hairpins, assuming several situations. In these situations, it was possible to fix a wider range or various shapes more conveniently using a hair-fixing sheet than using several hairpins at a similarly low cost. In addition, it was easy to change the hair to be fixed, remove it postoperatively, and prevent the hair from being pulled out, thereby preventing additional postoperative pain.

In this study, we tried to investigate the efficacy of combined light therapy using low-power lasers at 655 nm and LEDs emitting wavelengths at 625 ± 5 nm and 850 ± 10 nm in hair loss and scalp. A total of 33 subjects were enrolled in this clinical trial. Each subject used the LLLT and LED device on the scalp for 10 min on a daily basis for 12 weeks. After 12 weeks of LLLT and LED device use, there were significant improvements in redness, elasticity, and hydration of the scalp. Additionally, hair luster and tensile strength were improved. A remarkable decrease in total shed hairs was observed in all subjects at 4, 8, and 12 weeks without any serious adverse event. Combined light therapy using LLLT and LEDs proved to be an effective treatment for reducing hair loss and improving scalp condition.

Recently, research on variables associated with hair styles are increasing with the spreading of total coordinated intention in the fields of clothing and cosmetology. In the present study, we focused on examining the skin temperature on the scalp(the vertex, temporal, and occiput), humidity on the occiput, skin temperatures (the forehead, back of ear, back of neck, upper back, abdomen, forearm, hand, thigh, calf, and foot), rectal temperature, total body mass loss by hair styles in a thermal neutral environment. Four young females participated as subjects. For a certain period, each subject had the five different hair styles in a random order: (1)Straight short hair(SS), (2)Perm waved short hair(PS), (3) Straight long hair(SL), (4)Perm waved long hair(PL), (5)Ponytail style(PT). Subjects wore briefs, bra, shirts with long sleeves, long legged training pants, and socks. The environmental variables of a climatic chamber were kept constant at $21{\pm}0.5^{\circ}C$ of air temperature and 55${\pm}$5%RH of air humidity. The results indicated the following: The skin temperature and humidity on the scalp did not show any significant differences among five different hair styles, but straight long hair style(SL)was the highest on the vertex, temporal, and occiput. The temporal skin temperature($29.8\sim30.8^{\circ}C$) was the highest, while the vertex skin temperature($28.7\sim30.1^{\circ}C$) was the lowest. Humidity on the occiput was the highest in the perm waved long hair style(PL). The back of ear skin temperature was significantly lower in the ponytail style(PT) than in the other four hair styles(p<.001). In the straight long hair style(SL), the skin temperature on the back of the neck and on the upper back were significantly higher than those of the other four hair styles(p<.01). Mean skin temperature and rectal temperature had no significant differences among hair styles. Total body mass was the highest in the perm waved long hair style(PL)(p<.05). We acquired fundamental data to enable the improvement of the current hair clinic system, wigs, functional hats, and helmets.

There exist some restrictions and difficulties in performing follicular unit extraction (FUE) in white-haired patients, for several reasons. In this paper, we introduce a novel technique for visualizing white hair during the punching procedure and graft preparation in FUE for white-haired patients. In white-haired older male patients, we dyed the surrounding scalp skin purple with a gentian violet solution-stained toothpick. Our method has several advantages: surgeons can easily focus on the center of the follicular unit and rapidly perform punching, they can recognize the condition of the harvested follicular units during FUE, and the hair transplant team can secure a clear view for trimming and loading into the implanter. We suggest that scalp dyeing in difficult FUE procedures, especially in patients with white hair, may be a simple method that provides a good visualization for donor site harvesting and for microdissection.

This study was carried out to identify bacterial strains adhered to human scalp hair and to investigate the antibiotic susceptibility of them. A total of 39 isolates were obtained from patients in intensive care units and healthy persons. The most common species isolated was Staphylococcus epidermidis (19 isolates), followed by S. aureus (14 isolates), S. waneri (5 isolates), and S. pasteuri (1 isolate). The susceptibility of isolates to amikacin, ampicillin, bacitracin, carbenicillin, cefazolin, cefoperazone, chloramphenicol, erythromycin, gentamicin, methicillin, nalidixic acid, neomycin, oxacillin, penicillin, streptomycin, tetracycline and vancomycin was determined by the disk diffusion method. All of the antibiotic resistant isolates were obtained from patient scalp hair. To examine the effect of conventional shampoo and detergent SDS on removing of bacteria from hair, we treated hair with culture solution of S. aureus. The bacteria attached to hair were not removed even by repeated washing with detergents. These results suggested that hair could be a source of bacterial contamination in hospital.
