exposome UV radiation pollution genetics physiological changes hair damage hair aging

TLDR Various factors like genetics, pollution, and lifestyle choices can damage hair over time.

The document examines the impact of the exposome on hair health, highlighting how internal and environmental factors contribute to hair weathering and aging. It notes that hair structure and damage susceptibility vary across ethnicities, with African hair being more prone to breakage. Key factors include nutrition, stress, sleep, smoking, and UV radiation, which can accelerate hair aging and affect hair follicle stem cells. Environmental factors like pollution and cosmetic procedures also contribute to hair damage. The study emphasizes the need for a comprehensive understanding of these factors to address hair health issues effectively and calls for further research to develop advanced treatments and preventive strategies.
