Discussions regarding hair health focus on the impact of seasonal changes, nutritional intake, and psychological stress. The transition to autumn in September and October can lead to increased hair shedding as part of the natural hair renewal cycle, a phenomenon known as “seasonal telogen effluvium.” Experts suggest that increased hair loss during autumn is often a biological response to summer conditions, such as sun exposure, heat, chlorine, salt, and sweat, which can sensitize the scalp and cause follicles to enter the resting phase. This results in visible shedding several weeks after the initial exposure. Beyond seasonal shifts, prolonged stress is identified as a significant disruptor of the natural hair growth cycle. Continuous pressure from work, family, sleep deprivation, or financial worries can cause the body to release elevated levels of cortisol. This hormonal response may cause more hairs to enter the resting phase simultaneously, with shedding often appearing some time after the stressful period rather than immediately. To manage hair fragility, nutritional support is emphasized. Dr. Malena García Arredondo advises against assuming that autumn requires universal vitamin or mineral supplementation, noting that supplements should only be used to correct specific deficiencies. A balanced diet rich in deficiencies, such as protein, iron, zinc, vitamin D, and biotin is recommended for overall wellness. Regarding topical care, stylist Álvaro Sámchez notes that caffeine-based hair tonics may help strengthen hair by supporting follicle activity, though he cautions these are cosmetic aids rather than medical treatments for alopecia. Medical professionals continue to advise seeking consultation for persistent heavy shedding, localized baldness, or scalp irritation. biotin. In autumn 2026, specialists have observed a particularly intense wave of seasonal hair loss. Dermatologist Claudia Bernárdez indicates and other experts indicate that this heightened loss may be linked to prolonged exposure to ultraviolet radiation during the summer of 2026. 2026, which can cause scalp inflammation, oxidative stress, and follicular obstruction. Other contributing factors include high temperatures and deficiencies in iron or Vitamin D, particularly in women. Medical professionals note that losing up to 1,800 hairs per week is considered normal. However, they advise seeking consultation if loss persists for more than two months or is accompanied by significant scalp inflammation. Experts also clarify that frequent shampooing does not increase hair loss; rather, maintaining a clean scalp is essential to mitigate the effects of sweat, smog, or helmet use.
