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.

Problems with scalp lead to hair loss, dandruff, itchiness, and other illness. No clear causes of these problems have been found and it is difficult to treat them. Therefore, the best way to prevent and treat any problems with scalp is to maintain physiological homeostasis of scalp to keep it healthy. Recently, many scalp and hair product brands have attempted to use medicinal herbs which have been extracted in hot water and mixed with other ingredients due to mass-production and standardization issues. However, many nutrients and active substances are destroyed by hot-water extraction. Therefore, this study has applied low-temperature rendering to minimize destruction of substances to extract black beans, peony, and green tea that are known to improve conditions of scalp. Then, their contribution to the improvement of scalp health was assessed. In result, it was found that low-temperature rendering retains over two times greater anti-oxidizing strengths than hot-water extraction and that the extracts from low-temperature rendering effectively strengthen follicles and hair, moisturize scalp, and prevent itchiness. Therefore, low-temperature rendered black beans, peony, and green tea extracts can be used to make effective scalp treatments.

Cardiofaciocutaneous (CFC) syndrome is characterized by dysmorphic features, cardiac anomalies, and cutaneous abnormalities. CFC syndrome belongs to the class of Noonan-related diseases. CFC syndrome can be clinically differentiated from other Noonan-related diseases by the distinct craniofacial features of sparse hair, a hypoplastic supraorbital ridge, exophthalmos and nystagmus, and skin manifestations such as ichthyosis and hyperkeratosis. However, phenotypes can overlap among Noonan-related syndromes, including CFC syndrome. Recently, several genes in the RAS-MAPK pathway have been identified as disease-causing genes for Noonan-related diseases. Here, we report on a Korean girl diagnosed with CFC syndrome caused by a V-raf murine sarcoma viral oncogene homolog B1 (BRAF) gene mutation, and we discuss the phenotype-genotype heterogeneities in Noonan syndrome and Noonan-related diseases.

Seborrheic dermatitis (SD) is the skin disease occurred because of Malassezia yeast which grows on the skin and scalp, and this yeast lives on sebum lipid, and their metabolite, free lipid acids are thought to be the main irritant on skin. To find out effective cosmeceutical ingredients to treat SD symptoms, we established novel cell-based in vitro model mimicking SD symptoms. This in vitro model adopted the co-culture system with primary sebocyte & HaCaT keratinocyte. We used M. globosa yeast extract, arachidonic acid, linoleic acid and dihydrotestosterone as SD inducers. In the co-culture system with optimized concentrations for SD-inducing cocktail, the production of IL-8 and sebum lipids increased up to 2-fold, and then we screened with commercial essential oils by monitoring IL-8 as a key inflammatory biomarker. Then we found that Cinnamomum zeylanicum oil, Mentha arvensis oil effectively down-regulated IL-$1{\alpha}$, IL-6, IL-8 cytokines which over-produced by SD-inducing cocktail. Additionally, two essential oils also showed inhibitory effect on sebum lipid synthesis from primary sebocyte and growth inhibitory effect to M. globosa yeast (MICs were lower than 0.0625 %). Our recent results suggest that Cinnamomum zeylanicum oil and Mentha arvensis oil could be effective natural herbal remedies to relieve or protect scalp seborrheic dermatitis.

Today all kinds of smart devices are being developed with various researches on wearable devices that support smart computing on the human body. Skin diseases continue to rise including freckles, pimples, atopy, and scalp trouble due to the environmental and genetic factors, and people pay bigger medical bills to treat their skin diseases. There is thus a need to develop a smart-phone or table-based smart healthcare imaging system of high portability and diagnostic accuracy capable of analyzing and managing various skin problems related to skin care. This study proposed an integrated system combining the Smart Mi Band, a wearable device using moisture and UV sensors based on IoT, on the hardware part with the sensor information monitoring software.

Alopecia areata (AA) is a common and tissue-specific autoimmune disease of hair follicle resulting in the loss of hair on the scalp and elsewhere on the body. Hair follicles is a unique organ because it has its own immune system and hormonal milieu and has a different immune state at each hair cycle stage. The collapses of anagen-dependent hair follicle immune privilege arise autoimmune attack, inducing ectopic MHC class I expression in the hair follicle epithelium and autoantigen presentation to autoreactive CD8+T cells, which results in AA. Clinical and experimental studies have pointed that psychological stress may also influence the hair follicle immune/hormone systems and contribute to the induction of AA. The key pathogenesis of AA is associated with immune privilege guardians (including ACTH, ${\alpha}-MSH$, and $TGF-{\beta}$), natural killer group 2D-positive (NKG2D+) cells (including NK and CD8+T cells), and stress hormones (including CRH and substance P). Effective treatments for AA are still demanded. One of the future targets of treatment will be the modification of hair follicle immune privilege including stress. Recent studies have reported that JAK inhibitors and immunomodulators used in other autoimmune disease, such as psoriasis, atopic dermatitis, and rheumatoid arthritis, Tregs, platelet-rich plasma therapy, statins, and prostaglandin anaolgues are effective for AA. Here the article reviews the recent understanding in the pathogenesis associated with perifollicular endocrine/immunology and new treatments of AA.

A case is described, where an adolescent boy developed alopecia areata and alopecia totalis during the course of routine orthodontic treatment for the resolution of a dentoalveolar Class II division 1 malocclusion. The orthodontic treatment lasted 22 months, with a successful outcome. However, within eight months of the onset of treatment the patient lost all his hair Exhaustive medical tests and differential diagnosis determined that the etiolgy of the patient's alopecia was psychological stress evoked by the orthodontic treatment. Numerous reports suggest that psychological stress can cause alopecia by affecting the immune system. Therefore, it appears reasonable to assume that in the case of this patient, alopecia had resulted from stress effects on the immune system, leading to autoimmune disease-like conditions in tissues surrounding the scalp hair follicles. The alopecia condition was successfully reversed by daily oral and topical applications of vitamin D. It is concluded that the immune system plays a pivotal role in tissue remodeling around the teeth and elsewhere in the body, and that any conditions capable of affecting this system may cause unfavorable outcomes, such as alopecia.

Malassezia furfur is an important causal factor for seborrheic dermatitis. Nowadays, the drugs available to treat this fungal infection are few. Several studies have documented the biological activity of essential oils. However, its antifungal properties are not completely understood, especially its anti-Malassezia activity. The aim of this study were to evaluate the effect of the plant essential oils on the growth of M. furfur using disk diffusion method and analyze by Gas chromatography-mass spectrometry (GC-MS) most active essential oils. In first screening, the 17 plant essential oils have possesses inhibitory activity against M. furfur at 2 mg/mL. Among the plant essential oils, oil of Citrus auranifoli was most active against M. furfur and its activity showed dose dependency. This anti-malassezial activity was high than that of itraconazole at 2 mg/mL. Oil of Citrus auranifolia also was phytochemically examined by GC-MS analysis, its main constituents were identified as limonene, ${\gamma}$-terpinene and terpinolene. It can be concluded that essential oils of Citrus auranifolia may have interesting applications to control fungal-derived diseases.
