With each shift in season many people notice subtle shifts in their hair density and fall-out. While factors like stress, diet, and genetics play a well known role in hair health, an increasing body of data indicates that seasonal hormonal fluctuations also strongly modulate how hair cycles through its life stages throughout the year. These changes are not random but are tied to the body’s natural response to environmental cues such as daylight, temperature, эпиляция ноги and even humidity.

During autumn and the onset of winter it is common to see more noticeable fallout. This is often triggered by surging stress hormone production, the catabolic hormone, which can be influenced by the shorter days and cooler temperatures. Additionally, melatonin levels escalate as nights stretch. Increased melatonin is linked to a delay in follicle activation, known as the resting stage. After the resting period closes, shedding occurs, accounting for the increased presence of more hair in their brushes during autumn.

When daylight expands in the warmer months when photoperiod lengthens, the body elevates serotonin levels and diminishes its nocturnal surge. This endocrine transition appears to stimulate follicles to enter anagen, called the growth stage. Clinically, patients frequently describe thicker, fuller hair during these months, and dermatologists often observe a higher rate of new hair growth in clinical settings during this time. Such cyclical enhancement could be an evolutionary adaptation, preparing the body for increased sun exposure and physical activity.

Sex hormone concentrations also shift gradually with the seasons, influencing scalp hair quality and resilience. Estrogen is known to promote hair retention and is modestly increased during summer, which may help explain why female individuals experience reduced hair fall during warm weather. On the other hand, men may experience a modest surge in testosterone effects during the end of summer, which can affect the scalp’s oil production and heighten risk for reduction in those predisposed to androgenetic alopecia.

This should be recognized that these endocrine variations are physiologically normal and short-lived. They do not reliably signal an systemic disorder. If hair thinning worsens or continues or persists beyond a few months, it may be advisable to assess diet, stress levels, or medical conditions such as thyroid disorders.

Awareness of cyclical hair behavior can help individuals manage their expectations and adopt gentle hair care routines adapted to seasonal cues. For example, using nourishing oils in the fall to prepare strands for seasonal transition, or focusing on scalp circulation and light therapy in the spring to support new growth. Controlled sunlight exposure may also help by elevating serum D3 levels, which supports follicle stem cell renewal.

Hair development follows a dynamic rhythm and follows a rhythm shaped by both internal hormones and external environments. Acknowledging this seasonal pattern, we can approach hair care with patience and awareness, knowing that what we see today may simply be one chapter in the annual narrative of hair renewal.
