Few studies have extensively examined the prevalence of hair care practices and their association with scalp and hair conditions in African American girls.
We sought to determine the prevalence of hair care practices and their association with traction alopecia, seborrheic dermatitis (SD), and tinea capitis (TC).
A questionnaire was administered to caregivers of African American girls aged 1 to 15 years. Multivariate analyses were performed to determine the association of hair care practices with reported disorders.
A total of 201 surveys were completed from dermatology (n = 98) and nondermatology (n = 103) clinics. Mean patient age was 9.8 ± 4.4 years. Essentially all respondents reported use of hair oils/grease (99%). Ponytails, braids, and cornrows were worn by 81%, 67%, and 49% of girls, respectively, within the past 12 months. In all, 61% reported hair washing every 2 weeks; 80% used hot combs; and 42% used chemical relaxers. Cornrows were significantly related to traction alopecia among respondents from nondermatology clinics only: adjusted odds ratio = 5.79 (95% CI 1.35-24.8, P = .018). Hair extensions and infrequent hair oil use were significantly related to SD: adjusted odds ratio = 2.37 (95% CI 1.03-5.47, P = .04) and 3.69 (95% CI 1.07-12.7, P = .039), respectively. No significant associations were observed for TC.
Small sample size and disorders reported by caregivers were limitations.
Certain hair care practices were strongly associated with development of traction alopecia and SD. No association was found between hair washing frequency and SD or TC, or between hair grease use and TC. These results can be used to inform practitioners, advise parents, and adapt treatment regimens to accommodate cultural preferences.
很少有研究广泛检查头发护理的流行，并将其与非裔美国女孩的头皮和头发状况联系起来。
我们旨在确定头发护理的流行，并将其与牵引性脱发、脂溢性皮炎（SD）和头癣（TC）联系起来。
向年龄在 1 至 15 岁之间的非裔美国女孩的照顾者发放问卷。进行多变量分析以确定头发护理与报告的疾病之间的关联。
共完成了 201 份来自皮肤科（n=98）和非皮肤科（n=103）诊所的调查。平均患者年龄为 9.8±4.4 岁。几乎所有受访者都报告使用发油/发脂（99%）。过去 12 个月中，分别有 81%、67%和 49%的女孩扎马尾辫、辫子和玉米辫。总共有 61%的人报告每两周洗一次头发；80%的人使用热梳子；42%的人使用化学直发器。只有来自非皮肤科诊所的受访者，玉米辫与牵引性脱发显著相关：调整后的优势比=5.79（95%CI 1.35-24.8，P=0.018）。发夹和不常使用发油与 SD 显著相关：调整后的优势比=2.37（95%CI 1.03-5.47，P=0.04）和 3.69（95%CI 1.07-12.7，P=0.039）。未观察到 TC 与任何显著关联。
样本量小和照顾者报告的疾病是局限性。
某些头发护理与牵引性脱发和 SD 的发展密切相关。头发清洗频率与 SD 或 TC 之间，或发油使用与 TC 之间没有关联。这些结果可用于为从业者提供信息，为家长提供建议，并调整治疗方案以适应文化偏好。
