Hair Thinning

Meaning

Hair thinning, clinically referred to as alopecia, is the gradual and progressive reduction in both the density and the diameter of hair fibers across the scalp, often serving as a visible manifestation of underlying systemic or localized physiological changes. This common dermatological presentation is frequently and intricately linked to hormonal fluctuations, including those associated with andropause, menopause, or thyroid gland dysfunction. It fundamentally represents a disruption in the normal, cyclical hair growth phases, shifting the balance away from the anagen (growth) phase toward the telogen (resting) phase. Addressing the root hormonal imbalance is a key, evidence-based strategy for the clinical management and restoration of follicular health.
