Impact of Hair Extension Safety Education on Scalp and Hair Health Practices among Female University Students in Nigeria

Abstract

Hair extensions are widely used among female university students in Nigeria for personal grooming, fashion, cultural expression, and appearance enhancement. Although hair extensions can provide temporary styling benefits, inappropriate installation, excessive tension, prolonged use, poor maintenance, inadequate scalp hygiene, and unsafe removal practices may contribute to scalp irritation, hair breakage, traction-related hair loss, infections, and other scalp and hair problems. Female university students may be particularly exposed to these risks because of frequent changes in hairstyles, use of tightly fitted extensions, limited knowledge of safe installation and maintenance, and reliance on informal beauty advice. Hair extension safety education provides an opportunity to improve awareness of potential scalp and hair risks and promote healthier practices before, during, and after the use of hair extensions. Against this background, this study investigates the impact of hair extension safety education on scalp and hair health practices among female university students in Nigeria. The study will be anchored on the Health Belief Model, Social Cognitive Theory, and Health Literacy Framework. The Health Belief Model explains how female students' perceptions of susceptibility to scalp and hair problems, perceived severity, perceived benefits of safe hair-extension practices, perceived barriers, and cues to action may influence their behaviour. Social Cognitive Theory emphasizes observational learning, peer and social influence, self-efficacy, reinforcement, and environmental factors in shaping hair-care practices. The Health Literacy Framework emphasizes students' ability to access, understand, evaluate, and apply information concerning hair-extension safety, scalp health, and appropriate hair-care practices. Collectively, these theoretical perspectives provide a suitable framework for explaining how hair extension safety education may influence scalp and hair health practices among female university students in Nigeria. The study will adopt a quantitative quasi-experimental or analytical cross-sectional research design. The study population will comprise female undergraduate and postgraduate students aged 18 years and above enrolled in selected public and private universities across Nigeria. A multistage sampling technique will be used to select geopolitical zones, states, universities, faculties or departments, levels of study, and eligible participants. Hair extension safety education will be assessed using indicators such as exposure to educational sessions, frequency and duration of education, information on appropriate installation, tension management, duration of wear, scalp hygiene, hair and scalp preparation, safe removal, cleaning and maintenance of extensions, recognition of scalp irritation and hair damage, appropriate use of hair-care products, professional hair-care guidance, and when to seek medical or dermatological care. Scalp and hair health practices will be assessed using indicators such as avoiding excessively tight hairstyles, allowing adequate periods between extensions, maintaining scalp cleanliness, washing and caring for the scalp appropriately while wearing extensions, avoiding excessive chemical or heat exposure, monitoring for pain or irritation, reducing tension when discomfort occurs, using appropriate hair-care products, maintaining adequate hair and scalp moisture, practising safe extension removal, avoiding sharing personal hair-care tools where appropriate, and seeking professional healthcare advice for persistent scalp or hair problems. Data will be collected using structured questionnaires, standardized hair and scalp health knowledge and practice assessment tools, hair-care practice assessments, scalp observation checklists where appropriate, and relevant university health programme records. Descriptive statistics will be used to summarize participants' characteristics, hair-extension use patterns, types of extensions used, duration of use, sources of hair-care information, and scalp and hair health practices. Inferential statistical techniques, including chi-square tests, t-tests, correlation analysis, and logistic or multiple regression analysis where appropriate, will be used to determine the impact of hair extension safety education on scalp and hair health practices. Where a quasi-experimental design is adopted, health-practice scores before and after the educational intervention may be compared with those of a comparison group to determine changes associated with the intervention. Diagnostic tests will also be conducted to assess the reliability, validity, and robustness of the findings. The study is expected to find that hair extension safety education has a significant positive impact on scalp and hair health practices among female university students in Nigeria. Students exposed to structured and practical hair-extension safety education are expected to demonstrate healthier scalp and hair-care practices than students without comparable exposure. Education may improve awareness of the relationship between excessive tension, prolonged extension use, poor scalp hygiene, and hair or scalp problems. Practical demonstrations may encourage students to avoid excessively tight installations, monitor for pain and scalp irritation, maintain appropriate scalp hygiene, allow adequate recovery periods between hairstyles, and remove extensions safely. Students may also become more likely to recognize early signs of traction-related hair damage, scalp infection, or persistent irritation and seek appropriate professional care. However, fashion trends, peer influence, beauty standards, social-media content, cost of professional hairstyling, cultural preferences, time constraints, and limited access to trained hair-care professionals may reduce the effectiveness of education alone. The study therefore expects accessible, practical, culturally appropriate, and sustained hair extension safety education, supported by appropriate professional guidance, to contribute significantly to improved scalp and hair health practices among female university students in Nigeria. The study is expected to contribute to the literature on hair-extension safety, scalp health, hair health, traction-related hair loss, women's health, cosmetic safety, health education, personal grooming practices, dermatological health, and public health in Nigeria. The findings will provide useful information to the Federal Ministry of Health and Social Welfare, Federal Ministry of Education, universities, university health centres, dermatologists, healthcare professionals, cosmetologists, hairstylists, public health practitioners, student organizations, women's health organizations, development partners, and policymakers regarding strategies for promoting safer hair-care practices among young women. The study will also provide evidence-based recommendations for integrating hair and scalp health education into university health programmes, improving awareness of safe hair-extension practices, strengthening education on tension-related hair damage, encouraging appropriate scalp hygiene, promoting early healthcare-seeking for persistent scalp and hair problems, and developing culturally appropriate health communication strategies for protecting scalp and hair health among female university students across Nigeria.
