Recently. dyeing by harmless natural materials has received much attention due to the side-effects occurred from dyeing by synthetic dyes. In this study, we examined the effect of extracts of Pueraria thunbergiana (P. thunbergiana) roots, which are treated as natural products as well as agricultural wastes, on the hair dyeing by measuring dyeing interval, temperature, density changes, mordant and chromatic faction. The hair dyeing by the extracts significantly reduced hair damage and kept cuticle of hair softer than that by synthetic dyes. In addition, since a mordant is one of the necessary additives in dyeing, the role of a mordant was studied and concluded to be a supplementary substance based on the results that the hair dyeing by the extracts of P. thunbergiana roots alone was much darker than the others. Taken together, the data presented in this study suggest that the extracts of P. thunbergiana roots are is less damageable to hair and thus can be more safely applicable to hair dyes than that by synthetic dyes.

Hair loss, also known as alopecia, is a common dermatological condition of psychosocial significance; development of therapeutic candidates for the treatment of this condition is, hence, important. Silibinin, a secondary metabolite from Silybum marianum, is an effective antioxidant that also prevents various cutaneous problems. In this study, we have investigated the effect of silibinin on hair induction using three-dimensional (3D) cultured, human dermal papilla (DP) spheroids. Silibinin was found to significantly increase viability through AKT serine/threonine kinase (AKT) activation in 3D DP spheroids. This was correlated with an increase in the diameter of the 3D DP spheroids. The activation of the wingless and INT-1 (Wnt)/${\beta}$-catenin signaling pathway, which is associated with hair growth induction in the DP, was evaluated using the T cell-specific transcription factor and lymphoid enhancer-binding factor (TCF/LEF) transcription factor reporter assay; results indicated significantly increased luciferase activity. In addition, we were able to demonstrate increased expression of the target genes, WNT5a and LEF1, using quantitative real-time PCR assay. Lastly, significantly elevated expression of signature genes associated with hair induction was demonstrated in the 3D DP spheroids treated with silibinin. These results suggest that silibinin promotes proliferation and hair induction through the AKT and Wnt/${\beta}$-catenin signaling pathways in 3D DP spheroids. Silibinin can be a potential candidate to promote hair proliferation.

Modern people express their beauty through hair coloring, but hair can be damaged by repeated chemical treatments. In order to increase the durability of dyeing and minimize the hair damage, in this study, the acidic amino acids including aspartic acid (Asp) and glutamic acid (Glu) were used to post-treat hair during hair coloring. The post-treatment with 0.75% Asp and Glu solution was carried out at room temperature for 20 minutes after dyeing bleached hair with cherry red and blue silver colors. After repeated shampooing of 1, 5, 10, 15, 20, and 25 times, L^*a^*b^* value of dyed hair was measured to confirm the dyeing durability, and the changes in tensile strength, porosity, and surface properties of the hair were also analyzed to determine the condition of the hair. In the case of cherry red and blue silver staining, the Asp and Glu experimental group showed higher color persistence than the control group, and the Asp and Glu experimental group showed higher tensile strength, lower porosity and smooth surface properties than the control group. In particular, the Asp test group showed superior color persistence and lower hair damage than the Glu test group. This study, therefore, if damaged in dyeing and bleaching in the field of hair after treatment with asp glu a combination of hair cosmetics in the development of basic data look forward to be.

As part of research to develop a permanent wave-reducing agent for hair, in the current study, 0.1%-1.0% of Polyquaternium-10 was added to a permanent reagent containing Nicotinoyl Dipeptide-23 to prepare the agent, which was tested on damaged hair. The pH change was relatively stable even after a date, but due to the hair's natural composition, 0.1%-0.6% of the Polyquaternium-10 concentration according to pH was suitable. The temperature safety experiment demonstrated it to be stable at a high temperature and at room temperature, but when a Polyquaternium-10 concentration of 0.9% or higher was added at 0℃, coagulation occurred. In terms of the force efficiency of permanent wave formation, wave efficiency lowered as the concentration increased: the longer the wave lasts, the lower the Polyquaternium-10 concentration. The permanent moisture content was found to be higher as the concentration of Polyquaternium-10 increased. Therefore, when Polyquaternium-10 is applied to the permanent wave-reducing agent, considering stability, permanent formation, durability, and moisture rate, the most suitable concentration was found to be that of Polyquaternium-10 in the cysteine-reducing agent. A novel finding from this study is that as the concentration of Polyquaternium-10 increases, the consistency of the permanent wave-reducing agent changes, shifting from a liquid to a viscous liquid formulation.

Melanin is one of the most important factors affecting skin color. Melanogenesis is the bioprocess of melanin production by melanocytes in the skin and hair follicles and is mediated by several enzymes, such as tyrosinase, tyrosinase related protein (TRP)-1, and TRP-2, MITF. In this study, we investigated the effect of Artemisia fukudo Makino extracts on tyrosinase activity and melanin production as natural products of whitening functional cosmetics. Melanin content in murine B16F10 melanoma cells were decreased by Artemisia fukudo Makino extracts in a dose-dependently. In addition, the inhibition of tyrosinase activity of Artemisia fukudo Makino extracts showed to decrease tyrosinase activity as the concentration of ${\alpha}-MSH$ was increased. Furthermore, western blot analysis revealed that Artemisia fukudo Makino extracts significantly downregulated the expression of tyrosinase, TRP-1 which treat of ${\alpha}-MSH-induced$ melanogenesis in murine B16F10 melanoma cells. As a result, Artemisia fukudo Makino extract showed functionalities as an effective whitening agent to inhibit melanin formation.

Hair is made of proteins containing various amino acids. Ultraviolet (UV) radiation is believed to be responsible for the most damaging effects of sunlight, and also plays an important role in hair aging. The purpose of this study was to investigate the changes in morphological and chemical structures after ultraviolet B (UVB) irradiation of human hair. The UVB-irradiated hair showed characteristic morphological and structural changes, compared to those of the normal hair. The result from a scanning electron microscope (SEM) equipped with an energy dispersive X-ray diffractometer (EDX) showed that the scale of UV-irradiated hair appeared to be rough and the amount of oxygen element was higher than that of the normal hair. Fluorescence and three dimensional (3D) topographical images were obtained by a confocal laser scanning microscope (CLSM). In 3D images, the green emission intensity of normal hair was much higher than that of fluorescing UVB-irradiated hair. The intensity of green emission reflects the intrinsic fluorescence of hair protein. Also, a fluorescent imaging method using fluorescamine reagent was used to identify the free amino groups resulting from a peptide bond breakage in UVB-irradiated hair. Strong blue fluorescence of UVB-irradiated hair, which indicates a very high level of amino groups, was observed by CLSM. Therefore, the fluorescamine as an extrinsic fluorescence could provide a useful tool to identify the peptide bond breakage in UVB-irradiated hair. Infrared image mapping was also employed to assess the cross-sections of normal and UVB-irradiated specimens to examine the oxidation of disulfide bonds. The degree of peak areas with strong absorbance for the disulfide mono-oxide was spread from the outside to the inside of hair. The spectroscopic techniques used alone, or in combination, launch new possibilities in the field of hair cosmetics.

In this study, the optimal conditions for hair dyeing using sappan wood (Caesalpinia sappan L.) powder were determined, and then the effect of chitosan treatment on the hair dyeing properties of sappan wood powder was investigated. Treatment of sappan wood powder and water with the ratio of 1:3 (w/w) at 40℃ for 60 minutes was found to be the most effective to hair dyeing. In addition, the pretreatment of low molecular weight (~30 kDa) chitosan at a concentration of 1% (w/w) prior to treatment with sappan wood powder effectively improved and maintained the hair dyeing properties of sappan wood. In conclusion, the low molecular weight chitosan is considered to be of great help as a mordant in improving the dyeing efficiency and retention of sappan wood powder in hair dyeing.

Modern people are investing a lot of time and economically in their appearance as a means of expressing their aesthetic desires. They have a lot of hair dyes that make up most of their appearance, but their hair damage is serious. Especially, they use hair dyes which are very popular among the hair cosmetics that make up most of their appearance, but their hair damage is serious. The purpose of this study is to investigate the hair tensile strength of hair with oxidative hair dye to induce styling while minimizing hair damage. The results showed that the Max. load, Max. stress, Max. elongation, break load, break stress, break elongation, maximum modulus and tangential modulus according to evaluation interval were significantly different between control and 8N-10N experimental groups. The maximum modulus and tangential modulus for the strain interval did not show tendency to increase or decrease constantly, although there was a difference between the control and experimental group. Therefore this study was conducted to investigate the correlation between hair loss and hair damage through the treatment of high grade oxidative hair dye, which is widely used in ield of industry. We want to provide application data.

This study the changing aspects in accessories, skin care and hair style in 「Maeil Shinmun」 from Jan. 1, 1946 to Dec. 31, 2000, and the results are as follows. In the period of 1946 to 1959, articles were about how to select accessories and the role of skin-protection cosmetics for skin care, and the cases of people wearing color makeup in pursuit of beauty increased. The hairstyle trend began to gradually shift from long hair toward short. During the time of 1960 to 1969, how to select accessories an also how to match them with clothes were dealt with in articles, and how to massage face or use pack for healthy skin was introduce. From 1970 to 1979, as the number of working women increased, proper use of accessories according to each occasion was introduced, and, for hairstyle, the way to keep their hair healthy and shine, rather than a fashion of its style itself, was emphasized. In 1980∼1989, as casual wear became so popular worldwide and a variety of way to use shoes, mufflers, scarfs, shawls, and hats to go with it were highlighted, practical fashion got in vogue and use of accessories with which individuality can be expressed in a simple way prevailed. During the time of1990 to 2000, the trend changed to the pursuit of chic using accessories that reveal wearers'individuality, and especially came the boom of charming schools and makeup lesson for skin care. The prominent trend was that men and women of the new generation expressed their individuality by having their hair partly dyed or fully dyed in various colors and tried to resemble famous entertainers. In particular, as people get more and more interested in body shape, various ways to take care of body were introduced, such as body care products and aroma treatments.
