Concentration Limits

The aim of this work was to optimize our natural hair dyeing system which we described in our previous work and to compare with other dyeing systems. Therefore, we investigated concentration limits of matcha and mordant and compared this new dyeing method with commercial permanent systems on the market. Completely unpigmented hair tresses were dyed with matcha powder (camelia sinensis) and iron(II)-lactate. To investigate the wash fastness and concentration limits, the differently dyed hair tresses were spectrophotometrically measured. The comparison of the damage potential for which cysteic acid is an indicator was measured by NIR. The concentration of matcha and mordant are responsible for the intensity of the color results. The higher the matcha or the mordant concentration, the darker the color results of the dyed hair tresses. Hair damage of matcha mordant dyeing is comparable with results of commercial permanent hair coloration systems. Moreover, the results of wash fastness of matcha mordant dyed hair tresses is comparable and even better by tendency to permanent colored hair tresses.

Record Review

The mechanism of alopecia areata (AA) is not well-elucidated, and hair follicle melanogenesis pathways are implicated as possible sources for autoantigens. After a retrospective medical record review at a single tertiary medical center, the hair color of 112 AA patients were identified and compared to a control group of 104 androgenetic alopecia patients. There were no statistically significant differences in the natural hair color prevalence between the 2 groups (<i>p</i> = 0.164), and hair color was not a predictor of the alopecia type. Our results suggest hair pigmentation, determined by the eumelanin-to-pheomelanin ratio, is not a positive risk factor for AA development. We hope that our study will encourage multiple large-scale, collaborative, retrospective medical reviews to determine if our results are reproducible in diverse patient populations.

ABSTRACTTechniques in hair transplantation have evolved recently which make results look more natural. Hair restoration is one of the most exciting and innovative surgical fields in aesthetic surgery today. A precise appreciation of anatomy has allowed the useof follicular unit grafts. With better methods of harvesting and implantation, hair transplantation results represent a blend of art and science.

Job Recruitment

Across four studies, we demonstrate a bias against Black women with natural hairstyles in job recruitment. In Study 1, participants evaluated profiles of Black and White female job applicants across a variety of hairstyles. We found that Black women with natural hairstyles were perceived to be less professional, less competent, and less likely to be recommended for a job interview than Black women with straightened hairstyles and White women with either curly or straight hairstyles. We replicated these findings in a controlled experiment in Study 2. In Study 3A and 3B, we found Black women with natural hairstyles received more negative evaluations when they applied for a job in an industry with strong dress norms. Taken together, this article advances the research on biases in the labor market in the age of social media use and highlights the importance of taking an intersectional approach when studying inequity in the workplace.
