In this study, we developed a scalp protect powder (scalp irritation abirritant). We proved this powder can lessen sensitivity of skin against diamine dyes (PPD, PTD, etc.) by carrying out safety test and clinical experiments. This scalp protect powder accelerates dyeing process, and reduces not only scalp irritation but also hair damage. Using our optimum formula, ammonia can be caught in liquid-crystalline structure, subsequently, bad odor is reduced dramatically.

Difficulties with intraoperative fixation of hair or eyebrow sometimes occur because of displacement or dislodgment of hair during surgery. So we have found that the simple application of a small transparent adhesive disposable dressing, such as $Tegaderm^{(R)}$ or OpSite $Flexigrid^{(R)}$, can prevent this. One of the advantages of this technique, compared with stapler fixation of the hair, is that it does not cause local trauma. An OpSite $Flexigrid^{(R)}$ or $Tegaderm^{(R)}$ is placed such that it covers both the scar and operation site hair. The hair or eyebrow were easily, quickly, and firmly positioned even on the nonshaved scalp. The technique seems to have no drawbacks, and when the $Tegaderm^{(R)}$ or Opsite $Flexigrid^{(R)}$ is removed, patient experiences little discomfort. We have never seen an allergic or direct traumatic cutaneous response following the use of these materials.

Total scalp avulsion is rare but a devastating injury. This condition burdens the patient with disfigured cosmetic appearance and permanent psychosocial trauma. Throughout history, this condition has been favored in women working with mechanics since the long hair function as a vector appliance for oblique pull of the hair into a stationary torque. We present our experience of the replantation of the total avulsed scalp in male, first to be reported in Korea. Warm ischemic time was exceeding 16 hours along with severe crushed condition of the detached margin, a relatively satisfactory result was obtained.

Scalp reconstruction is challenging because the scalp is inelastic, stiff, and has hair follicles. Tissue expansion offers aesthetically pleasing outcomes with minimal donor-site morbidity. However, in a scarred scalp, the extent of possible dissection for the expander insertion may be limited and surgeons must make use of the limited scalp tissue. We successfully reconstructed scarred scalps using rectangular expanders. This report presents two cases: a 4×3 cm chronic defect with widespread scarring and osteomyelitis and an 11×7.5 cm scar tissue following a skin graft. Tissue expanders were inserted in the subgaleal plane and were inflated by 195 mL and 400 mL over periods of 2 and 3 months, respectively. Subgaleal elevation of a fasciocutaneous flap was achieved with the expanded tissue. The defects were well covered, with good color, texture, and hair-bearing tissue. There were no complications involving the tissue expanders. Rectangular expanders yield more available tissue than round or crescent-shaped expanders. Moreover, since the base of the flap is well defined, the expander can be easily inserted in a limited space. Therefore, rectangular expanders are recommended for the reconstruction of scarred scalps.

Purpose: Opposing portal irradiation with helmet field shape that has been given to a patient with brain metastasis can cause excess dose in patient's scalp, resulting in hair loss. For this reason, this study is to quantitatively analyze scalp dose for effective prevention of hair loss by comparing opposing portal irradiation with scalp-shielding shape and tomotherapy designed to protect patient's scalp with conventional radiation therapy. Materials and Methods: Scalp dose was measured by using three therapies (HELMET, MLC, TOMO) after five thermo-luminescence dosimeters were positioned along center line of frontal lobe by using RANDO Phantom. Scalp dose and change in dose distribution were compared and analyzed with DVH after radiation therapy plan was made by using Radiation Treatment Planning System (Pinnacle3, Philips Medical System, USA) and 6 MV X-ray (Clinac 6EX, VARIAN, USA). Results: When surface dose of scalp by using thermo-luminescence dosimeters was measured, it was revealed that scalp dose decreased by average 87.44% at each point in MLC technique and that scalp dose decreased by average 88.03% at each point in TOMO compared with HELMET field therapy. In addition, when percentage of volume (V95%, V100%, V105% of prescribed dose) was calculated by using Dose Volume Histogram (DVH) in order to evaluate the existence or nonexistence of hotspot in scalp as to three therapies (HELMET, MLC, TOMO), it was revealed that MLC technique and TOMO plan had good dose coverage and did not have hot spot. Conclusion: Reducing hair loss of a patient who receives whole brain radiotherapy treatment can make a contribution to improve life quality of the patient. It is expected that making good use of opposing portal irradiation with scalp-shielding shape and tomotherapy to protect scalp of a patient based on this study will reduce hair loss of a patient.

Objectives : Seborrheic dermatitis is common abnormal skin condition characterized by flaking and itch. In seborrheic dermatitis, the flakes are greasy and yellowish. Inflammation is also observed. Through this paper we can understand the process of seborrheic dermatitis of the scalp and confirm the scalp changes in the treatment process. The purpose of this study was to report the clinical effects of herbal medicine on Seborrheic dermatitis Methods : We employed oriental medical treatments; herbal-medication (Hyeongbangpaedoksangamibang), infant acupuncture, moxibustion and blood therapy. We treated her three times a week. She took medicine three times a day after a meal. During taking medicine, we let her avoid fatty food, flour based food. Her father took a picture the patient's head parts and we compared the symptom with previous symptom. With the picture, we evaluated the patient's scalp condition. Results : After taking treatment, the scalp condition of the patient was much improved. At first, yellowish to reddish scaly pimples appear along the hairline and itching was severe. There were thick and black crusts on the scalp, red, greasy skin covered with flaky white or yellow scales. After that the crusts were fell off and the itching was disappeared during the treatment period. And then the hair loss was occurred. After a year of treatment, scalp condition and hair were back to normal. Conclusion : Herbal medicine (Hyeongbangpaedoksangamibang) with oriental medical treatments was effective in the treatment of seborrheic dermatitis of the scalp and it helped to improve regenerating the scalp condition.

This study examines the role of six species of microalgae, including Phaeodacylum tricrnutum (PT), Chaetoceros gracilis (CG), Nanochloris oculata (NO), Pavlova lutheri (PL), Chlorella ellipsoidae (CE), and Scendedemus obliquus (SO), on hair loss prevention and scalp improvement. To determine the effects of microalgae extracts on hair loss prevention and scalp improvement, antioxidant activity, cell proliferation in HaCaT cells and HFDPC cells, and the inhibition level of 5-alpha reductase activity were examined. In the study of antioxidant activity, the $EC_{50}$ values of DPPH anti-radical activities indicated that the SO, CG, and ST9 treatment groups demonstrate significant antioxidant activity. In the study of the hydroxyl radical scavenging activity, CG (6.6~42.1%), ST9 (26.0~44.0%), and SO (7.8~44.3%) demonstrated significant effects. Furthermore, SO promoted the proliferation of HaCaT cells and a human epidermal cell line during a 6-day treatment. In the study of the proliferation of HFDPC cells, a hair follicle dermal papilla cell line, CG, and SO significantly stimulated cell proliferation. Finally, PT, CG, and SO significantly inhibited 5-alpha reductase activity. These results suggest that among the six microalgae used in this study, CG and SO have antioxidant effects, induce cell proliferation, inhibit 5-alpha reductase activity, and can be used for hair loss prevention and scalp improvement.

The anthropometric measurements, nutrient intake, concentrations of minerals in scalp hair and urine and urinary 5-hydroxyindoleacetic acid(5-HIAA) of 30 autistic children not taking psychoactive drugs and 30 nonautistic control children were determined. The autistic children were taking significantly lower amounts of vitamin A, niacin, ascorbic acid and iron. The intake of vitamin A, niacin, and iron in autistic children were found to be 22$\%$, 75$\%$ and 58 of RDA, respectively. The decreased anthropometric measurements in height and weight of autistic children seems partly due to lower intake of these micronutrients. The food intake in vitamin and mineral group of autistic children was significantly lower. It is probably related to decreased intake of fruit in autistic children. There was no toxicity of cadmium and aluminum in both groups according to their contents in scalp hair. Autistic children showed elevated levels of hair calcium and zinc but lowered levels of copper and iron. The urinary excretion urinary excretion of 5-HIAA.

To ascertain the effects of hair dyeing application on oxidative stress in human, a mixture of permanent black colored hair dye with the same amount of oxidant containing 6% hydrogen peroxide was used. A hair dyeing with contacting the scalp (conventional dyeing) and a hair dyeing with 3 to 4mm away from the scalp (alternative dyeing) were applied to each 15 young healthy women. Blood was taken from the brachial vein at two sampling times, just before and 6 hours alter the hair dyeing, and antioxidant enzyme activities and antioxidant contents were measured in red blood cells. After dyeing, malondialdehyde(MDA) contents for conventional dyeing group was shown to a tendence of more increased than alternative dyeing group. After dyeing, reduced glutathione (GSH) contents for conventional dyeing group was shown to a tendence of more decreased than alternative dyeing group. After dyeing, superoxide dismutase (SOD) and catalase (CAT) activities were significantly decreased in conventional dyeing group (p < 0.01), however, SOD and CAT activities were not significantly decreased in alternative dyeing group. After dyeing, there was no significant decrease in glutathione peroxidase (GPX) activity both for conventional dyeing group and alternative dyeing group. Therefore, after dyeing, the degree of oxidative stress in red blood cells for alternative dyeing group was appeared to be lower than conventional dyeing group.
