Studysummary This study reviewed literature on hair growth and found that external factors like pollution, stress, and nutrition can adversely affect hair, concluding that a multifactorial approach and personalized nutrition monitoring are essential for effective hair loss therapy. Our plain-language summary of this paper — not a Tressless recommendation.
The article reviews the biological mechanisms of hair growth and assesses the impact of external factors such as ecology, chronic stress, and nutrition. It highlights how air pollution, UV radiation, and heavy metals can disrupt hair cycle phases and dermal papilla functions. Stress-induced hair loss is linked to HPA axis hyperactivity, neuropeptide signaling, and local inflammation. The study emphasizes the need for a comprehensive, multifactorial approach and nutritional monitoring for personalized hair loss therapy. This research is valuable for specialists in trichology, dermatophysiology, ecotoxicology, and nutrition, aiming to develop strategies to maintain hair follicle homeostasis.
