During autumn, especially in October and November, it is common to observe an increase in the usual hair loss. Humans lose about 50 hairs per day on a normal or physiological basis due to the life cycle of hair. A head hair has an average lifespan of about 4-5 years. The life of hair is divided into several phases: growth phase (anagen), involution phase (catagen) and shedding phase (telogen).

Myth or reality?

Research suggests that women suffer slightly higher rates of telogen during the month of July. The affected hairs in this telogen phase fall out about 100 days later, i.e. in mid-October or November. It seems that the cause of this increased drop is the stress caused by the intense summer heat. Other hypotheses suggest that during the summer months the hair grows more to protect itself from ultraviolet radiation and later in the fall hair loss increases.

Is it just autumn or are there other causes of hair loss?

Every year, hundreds of thousands of women and men suffer unexpected hair loss at any time of the year. What could be the cause?
Restrictive diets and intense physical exercise produce certain deficiency states in which hair and nails are the parts of the body most affected. In premenopausal women, iron deficiency is the most common cause of hair loss, sometimes due to heavy menstrual losses. In menopause, hormonal changes predispose to a loss of hair density and thickness. Thyroid problems can cause hair thinning and hair loss. Any physical or emotional stress also causes intense hair loss.

Should I worry if my hair falls out?

When hair loss is slight and recovers in the following months, there is no need to worry. However, if the hair loss lasts longer than 2 months and is clearly visible, it is advisable to see a dermatologist for an in-depth study of the problem and the most appropriate treatment for each situation.
