Objective: We sought to examine the factors that were associated with postpartum hair loss and to elucidate factors correlated with its pathogenesis. Methods: We carried out a questionnaire-based cross-sectional study. The study participants were women who delivered at 2 facilities and filled the questionnaire 10–18 months after delivery. The survey questionnaire included baseline characteristics, pregnancy details, delivery, childcare, and extent of postpartum hair loss. We divided participants into 2 groups according to the absence or presence of postpartum hair loss and performed logistic regression analyses. Results: A total of 331 (21.0%) responses were analyzed; among these 304 (91.8%) women had postpartum hair loss. The average time for the start, peak, and end of hair loss was 2.9, 5.1, and 8.1 months, respectively. Women with hair loss had an earlier time of delivery, a lower birth weight, a higher preterm labor rate, and longer-term breastfeeding. Logistical regression analyses revealed that longer-term breastfeeding and preterm labor were independent predictors of postpartum hair loss. The adjusted odds ratio for postpartum hair loss in women who ended breastfeeding 6–12 months postpartum versus those who ended it after 12 months or more was 5.96 (95% confidence interval [CI] [1.68, 21.09]) and 6.37 (95% CI [1.95, 20.76]) compared with those who stopped breastfeeding within 6 months postpartum. Limitations: Finer details such as pregnancy complications and delivery information may not be accurate since all results are based on questionnaire responses. There may be a sampling bias because women who suffer from postpartum hair loss may tend to participate more frequently. Conclusion: Over 90% of women experienced postpartum hair loss. Our data show that long-term breastfeeding and preterm labor correlate with postpartum hair loss.","PeriodicalId":102245,"journal":{"name":"International Journal of Women’s Dermatology","volume":"519 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123065161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ogunleye","doi":"10.1097/JW9.0000000000000089","DOIUrl":"https://doi.org/10.1097/JW9.0000000000000089","url":null,"abstract":"Background: Black haircare is an estimated $2.51-billion-dollar industry. Black women spend 9 times more on ethnic hair products than non-Black consumers. The haircare industry has adapted to these market trends by developing products catering to the needs of “natural hair,” referring to curly to tightly coiled hair texture that has not been chemically straightened with a relaxer. Anecdotally, natural haircare products are relatively expensive. Objective: We aimed to investigate texture-based price differences for haircare products targeting coily/curly compared to straight hair types. Methods: Data were collected in August 2022 from 6 brands available on www.amazon.com. After stratifying the data by manufacturer, hair texture, and average price/oz, we used 2 sample t-test with equal variances to examine cost differences. Results: Overall, there was a significant difference in average price/oz between all coily/curly and straight hair products, with coily/curly hair products being more expensive. When stratified by manufacturer, one leading US manufacturer sold coily/curly hair products at a higher price ($0.66/oz ±$0.05) compared with straight hair products ($0.46/oz ±$0.04), t14 = 2.8967, P < 0.0134. Limitations: A small sample size of only shampoos and conditioners were analyzed, which may not represent the number of haircare products that consumers use. Conclusion: Pricing policies should ensure that all individuals have access to effective, affordable haircare products. Dermatologists should also be cognizant of pricing differences to direct patients with natural hair to fairly priced products.","PeriodicalId":102245,"journal":{"name":"International Journal of Women’s Dermatology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115087079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective: This study aims to consolidate the available literature to characterize demographic and clinical features of mesotherapy-associated NTM infections. Methods: Using PRISMA guidelines, a systematic review of PubMed, Scopus, and Embase databases was undertaken for articles reporting cases of NTM skin infections following mesotherapy. Data were analyzed using Microsoft Excel. Results: Of 1966 search results, 30 articles (N = 423 patients) met inclusion criteria. Studies were largely from South America, and patients were mostly women aged 16-55 with NTM infections arising in the abdomen, buttocks, or thighs. Nearly all patients developed multiple, well-localized lesions without systemic symptoms. Effect summary by meta-analysis revealed most infections resolved after antibiotic therapy, though many patients required multiple antibiotic courses and/or agents to resolve infection. Infections often took weeks to resolve and were complicated by post-treatment scarring. Limitations: The main limitation of this study was the heterogeneity and lack of consistency between case reports. Conclusion: Cutaneous NTM infections associated with mesotherapy generally occur in women of childbearing age, arise from injections contaminated by the environment, and are often complicated by scarring/poor cosmesis and prolonged treatment course.","PeriodicalId":102245,"journal":{"name":"International Journal of Women’s Dermatology","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128403702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
