Seasonality of hair shedding refers to the natural variation in the amount of hair we shed throughout the year. Research suggests that many people experience increased hair shedding during late summer and early fall. This seasonal pattern is believed to be influenced by changes in daylight exposure, temperature, and possibly hormonal fluctuations linked to environmental factors.
Hair shedding occurs during the telogen phase of the hair growth cycle, when hair follicles rest before new growth begins. During seasonal shedding periods, a higher percentage of hair may transition to the telogen phase, resulting in more visible hair loss. This phenomenon is more noticeable for individuals with longer hair or those who closely monitor their hair.
Seasonal shedding is a normal biological process and should not cause alarm unless accompanied by other symptoms, such as excessive thinning or patchy hair loss.
