“…Women (≥18 years) of African descent were recruited from staff, students, patients and visitors (as well as female friends and relatives), at a hospital in London, UK, over a 9‐month period following ethical approval (REC Reference: 12/LO/1758). After taking informed written consent, subjects were asked to complete a validated, 36‐point questionnaire exploring their demographics, current and past hair grooming practices as well as motivating factors for hairstyle choices . In this study, descriptive statistics (frequencies and percentages for categorical variables, and means and confidence intervals for continuous variables) have been used to summarize pooled data from 242 subjects recruited into this study, to provide data on the hair grooming practices of women of African descent in the UK.…”

“…Hair and scalp disorders are a significant problem in people of African descent, being consistently cited as one of the leading dermatological problems in this cohort, in both hospital‐ and community‐based studies . In particular, hair loss is a significant problem in women of African descent, with a recent cross‐sectional study of adult women of African descent in London, United Kingdom (UK), demonstrating a sample proportion of hair loss of 54% . These data being limited by the lack of objective clinical assessment for hair loss.…”

This review critically appraises the reported differences in human hair fibre within three related domains of research: hair classification approaches, fibre characteristics and properties. The most common hair classification approach is based on geo-racial origin, defining three main groups: African, Asian and Caucasian hair. This classification does not account sufficiently for the worldwide hair diversity and intergroups variability in curl, shape, size and colour. A global classification into eight curl types has been proposed but may be too complex for reproducibility. Beyond that, hair cross-sectional shape and area have been found to have an inverse relation to curl: straighter fibres are circular with larger cross-sectional area, whilst the curlier fibres are elliptical with smaller cross-sectional area. These geometrical differences have been associated with bilateral vs homogenous distribution of cortical cell in curly vs straight hair respectively. However, there is no sufficient data demonstrating significant differences in hair amino composition, but proteomic studies are reporting associations of some proteins with curly hair. Eumelanin's relative abundance has been reported in all hair colours except for red hair which has a high pheomelanin content. Higher tensile and fatigue strength of straight hair are reported, however, curly hair fragility is attributed to knotting, and crack and flow formations rather than the structural variations.African hair has been found to have the highest level of lipids, whilst the water sorption of Caucasian hair is the highest, and that of Asian hair the lowest. Not all comparative studies clearly report their hair sampling approaches. Therefore, to strengthen the robustness of comparative studies and to facilitate cross-study data comparisons, it is recommended that the following hair defining characteristics are reported in studies: hair cross sectional diameter/area, curl type, hair assembly colour, as well as where possible donor data (age/gender) and sample pooling approach.

Background Traction alopecia (TA) is very common in Africa but few studies on African population are available. We sought to determine factors associated with TA and measure the association between these factors and TA. Methods We carried out an analytical cross-sectional study in 29 hairdressing saloons in the city of Yaoundé. A questionnaire was administered and scalp exams were performed in order to look for TA and determine Marginal TA severity score if present. Participants were separated in two groups: TA group and a group without TA. Results We finally included 223 women (77 having TA and 146 without TA). The median age was 26 years for women with TA and 24 years for women without TA. The factors associated with traction alopecia we found included: age ≥ 35 years (adjusted OR = 4; p = 0.016). Hairdressing undertaken by hairdressers only (adjusted OR = 0.2; p = 0.008), the avoidance of the regular use of nets, caps and head ties (OR = 0.2; p = 0.006) and relaxing hairs once a year or less (adjusted OR = 0.2; p = 0.005) could be protective factors. As well, we found a positive correlation between age and TA severity (r = 0.235; p < 0.001). Conclusion Age and some haircare practices are associated to TA occurrence in our context. Women therefore need to be educated on these various factors that could be able to cause, worsen or prevent TA.
