Prevalence and Predictors of Premature Graying of Hair Before the Age of 30: A Cross-Sectional Study in Saudi Arabia.

Background: Graying is an inherent and unavoidable consequence of the aging process, impacting individuals of all genders. There are limited studies in Saudi Arabia that have examined the prevalence and predictors of premature graying of hair (PGH).

Objectives: This study aims to explore the prevalence and predictors of PGH before the age of 30 among the population of Saudi Arabia.

Methods: This is a cross-sectional online survey that was conducted between July 2023 and February 2024 in Saudi Arabia. Binary logistic regression analysis was used to identify risk factors of having gray hair before the age of 30.

Results: A total of 1193 participants were involved in this study. A significant portion of respondents reported having gray hair before the age of 30 (55.9%). The younger population (younger than 44 years), smokers, and those who have comorbidities, have anxiety, have depression, have a family history of gray hair before the age of 30 years, have a dry scalp, suffer from vitamin or mineral deficiencies, have hair loss due to immune diseases (such as alopecia), and use minoxidil or rosemary for hair loss were more likely to have gray hair before the age of 30 years (p < 0.05).

Conclusion: This study highlighted the high prevalence rate and associated predictors of PGH in Saudi Arabia. Identified predictors include genetic, health, and lifestyle factors. Healthcare professionals and decision makers are advised to promote the awareness of the general public on its risk factors to enhance the prevention of PGH. Public health initiatives include campaigns on smoking cessation, healthy nutrition, and mental health.
