Practical Approach to Hair Loss Diagnosis

Hair loss is one of the common complaints encountered in a cosmetic practice. Evaluating a patient with hair loss requires a thorough understanding of the various causes of hair loss and practical knowledge in hair cosmetics and hair styling procedures. A systematic approach in hair loss evaluation helps the treating physician in arriving at a diagnosis. Various bedside tests and advent of trichoscopy has empowered the physician in arriving at a diagnosis. This article aims to provide the physician a systematic approach in evaluating a patient with hair loss.

Growing up with black hair in the GTA: three women share their stories

The literature demonstrates that Black hair affects the identity of Black women. However, there is little research on how Black hair affects the identity of Canadian Black girls. For the purpose of this study, Black hair will refer to coiled textured hair, often referred to as “kinky”. The goal of the present study was to understand the effects of Black hair on the identity of Black girls between the ages of 5 and 12. Three Black women between the ages of 20 and 35 were asked to recall their experiences growing up in Canada with Black hair. Following a Black feminist approach, data was collected through story telling in an open-ended interview and four themes were identified : caring for Black hair, hair altering, the future of Black hair, and influences on Black hair styling. The women in the study have a hopeful vision for the future of Black hair. Keywords: Black hair, identity, Canadian context, childhood

Proteins as Hair Styling Agents

The perming of hair is a common styling procedure with negative impact on the overall properties of the hair fibers. Usually, this process uses harsh chemicals to promote the disruption of disulfide bonds and the formation of new bonds to change the shape of hair. Here, we explored bovine serum albumin (BSA), silk fibroin (SF), keratin and two fusion recombinant proteins (KP-UM and KP-Cryst) as new perming agents. A phosphate buffer prepared at different pH values (5, 7 and 9) was used to apply the proteins to virgin Asian hair, and a hot BaByliss was used to curl the hair fibers. To assess the potential of the protein formulations for hair styling, the perming efficiency and the perming resistance to wash were measured. Furthermore, the fiber water content was evaluated to assess if the proteins protected the hair during the styling process. Despite all of the proteins being able to assist in the curling of Asian hair, the best perming efficiency and perming resistance to wash results were observed for BSA and keratin. These proteins showed perming efficiency values close to that measured for a commercial perming product (chemical method), particularly at pH 5 and 9. The increase in the hair’s internal and external water contents revealed a protective effect provided by the proteins during the application of heat in the styling procedure. This study shows the potential of proteins to be used in the development of new eco-friendly hair styling products.

ДОСЛІДЖЕННЯ ТЕМПЕРАТУРНИХ РЕЖИМІВ В ПРИСТРОЯХ ЕЛЕКТРОПОБУТОВОЇ ТЕХНІКИ

The aim of the work is to improve the work of hair styling devices, which is aimed at increasing the efficiency of hair styling under the action of sufficiently high temperatures with the least damage to it. To achieve this goal, the following tasks were solved: the relationship between the physical properties of hair and temperature regimes of curling was analyzed; experimentally investigated the distribution of curling temperature during heating and cooling; the distribution of the temperature of the curling iron when heated with dry hair and with moist hair was experimentally studied. Methodology. The methods of mathematical modeling, methods of mathematical physics, methods of experimental researches with processing of results of experiment by means of a modern software product and computer equipment are used in the work. Findings. Analytical and experimental studies have shown the need for a uniform temperature field on the surface of the work surface to achieve the desired result. The necessity of temperature regulation in devices for work with hair is proven. Originality. The possibility of using the installation for experimental evaluation of temperature control in devices for working with hair is substantiated, which will significantly increase the time of continuous operation of the device and reduce electricity consumption. Practical value. A stand for research and analysis of different temperature regimes of electrical appliances has been developed. The thermostat circuit for temperature control in devices for work with hair is applied. It has been proven that you need to choose the temperature in relation to the condition and type of hair, so as not to cause great harm. Due to its small size, economic and technical indicators, this stand is easy to use when studying the temperature conditions in devices for working with hair in the work space, which contributes to more modern and demonstrative training. It is proposed to use the two-position law of temperature regulation for the surfaces of the working bodies.

Distinguishing Three Classes of Androgenetic Alopecia based on Concerns in Youth: Latent Class Analysis of a Cross-Sectional Survey

Background: While androgenetic alopecia (AGA) is a common condition, the concerns of youth about this condition, and how these concerns influence quality of life, personal well-being and health behaviour have been not been thoroughly investigated.Methods: Thai youth were asked to complete an AGA-related questionnaire including the dermatology life quality index, to assess their concerns and the clinical relevance. Latent class analysis was used for data analysis.Results: Data from 278 youth were collected. The mean participant age was 22 years (SD=0.79), and 57% of the participants were men; 94.6% of the participants reported any hair loss, mostly in the AGA severity of grade 1-2. A three-class model showed the best fit. Latent class 1 (LC1) participants (58%) had the lowest probabilities of concerns regarding AGA. LC2 participants (22%) had a generally low probabilities of AGA concerns, except when they were flirting, when they were with their lover and regarding how their hair looked when they were photographed. LC3 participants (20%) were the most concerned about AGA in all aspects. Compared with LC1 participants, LC3 participants were more often to use more than 3 hair styling products (relative risk, 6.7;1.5-29.6;P=0.013) and their AGA severity was more severe in both males (relative risk, 3.2;1.1-8.9;P=0.023) and females (relative risk,10.2; 3.3-31.0;P=<0.001).Conclusions: Youths who are more worried about AGA experience higher AGA severity and poorer quality of life, and are more likely to use multiple hair styling products.
