Abstract

Introduction: Hair plays a critical role in enhancing physical appearance, self-esteem, and identity. However, the impact of hair characteristics on daily life has received limited attention. This study aimed to assess the types and characteristics of hair, their variations according to age, gender, ethnicity, and country, and their effects on individuals' daily lives.

Methods: A study was conducted between February 2022 and June 2023 across nine countries: USA, France, Brazil, India, China, Mexico, Japan, South Africa, and Indonesia. A total of 19,461 participants aged 18 and older were selected using stratified, proportional sampling. Participants completed a structured digital questionnaire evaluating hair thickness, type, damage, and curl degree, alongside questions on stress, sleep, and well-being. Data were analyzed using descriptive statistics and statistical tests (T-test, Pearson's test).

Results: Thin hair was reported by 23.7% of males and 29.2% of females. Dry hair was more common in females (38.9%) than males (32.1%). Damaged hair was reported by 47% of females and 30% of males. Ethnic differences showed that thick hair was most common in African (40.7%) and least in Asian (26.3%) populations. The impact of hair type on daily life varied significantly across countries. Individuals with damaged or dry hair experienced higher stress, lack of sleep, and poor well-being, especially in Japan, India, and France. Hair type (straight, wavy, curly, kinky) also affected personal and professional stress levels differently in each country.

Conclusion: Our research shows that hair characteristics significantly influence daily life, self-image, and well-being, with notable variations by gender, ethnicity, and country. These findings highlight the need for interventions to address the psychological and social impacts of hair issues, contributing to better healthcare, body image, and product development.

全球头发的类型和特征：一项针对19461人的跨国研究的结果。

头发在提升外表、自尊和身份方面起着至关重要的作用。然而，头发特征对日常生活的影响却受到了有限的关注。这项研究旨在评估头发的类型和特征，它们根据年龄、性别、种族和国家的变化，以及它们对个人日常生活的影响。方法：一项研究于2022年2月至2023年6月在美国、法国、巴西、印度、中国、墨西哥、日本、南非和印度尼西亚等9个国家进行。采用分层比例抽样方法，共选取了19461名18岁及以上的参与者。参与者完成了一份结构化的数字问卷，评估头发的厚度、类型、损伤程度和卷曲程度，以及有关压力、睡眠和健康状况的问题。数据分析采用描述性统计和统计检验（t检验、Pearson检验）。结果：男性为23.7%，女性为29.2%。干发在女性（38.9%）中比男性（32.1%）更常见。47%的女性和30%的男性报告头发受损。种族差异表明，浓密头发在非洲人群中最常见（40.7%），在亚洲人群中最少（26.3%）。头发类型对日常生活的影响在不同国家差别很大。头发受损或干燥的人压力更大，睡眠不足，幸福感差，尤其是在日本、印度和法国。每个国家的头发类型（直发、波浪发、卷发、卷曲发）对个人和职业压力水平的影响也各不相同。结论：我们的研究表明，头发特征显著影响日常生活、自我形象和幸福感，并因性别、种族和国家而有显著差异。这些发现强调需要采取干预措施来解决头发问题对心理和社会的影响，从而有助于更好的医疗保健、身体形象和产品开发。

Normal and pathological processes in skin development and aging, their modification and treatment, as well as basic research into histology of dermal and dermal structures that provide clinical insights and potential treatment options are key topics for the journal. Patient satisfaction, preference, quality of life, compliance, persistence and their role in developing new management options to optimize outcomes for target conditions constitute major areas of interest. The journal is characterized by the rapid reporting of clinical studies, reviews and original research in skin research and skin care. All areas of dermatology will be covered; contributions will be welcomed from all clinicians and basic science researchers globally.
