Acute alopecia in winter: why it occurs and what to do

Why hair falls out particularly easily in winter and what you can do about it

Seasonal hair loss

Scientific studies show that intermittent hair loss is not a disease or unusual. In an extensive study, Professor Trüeb from the University of Zurich proved that there is a so-called seasonal hair loss . Therefore, the right hair care is particularly important in the cold season.

The hair growth cycle

Your scalp has around 100,000 hair follicles , each with a hair root. These hair follicles develop in a 3-phase cycle . There is the anagen phase, which is the growth phase, which lasts about 3-6 months. This is followed by the catagen phase, also called the transition phase, which lasts a few weeks. And finally the resting phase, which is called the telogen phase. It lasts about three months. Human hair is dormant during the telogen phase, which usually begins in late summer and early fall.

Since the telogen phase coincides with many external factors (physical and psychological) in autumn and winter , the old hair actively falls out and only a few new hairs grow back . Because of the unequal ratio, the hair loss becomes more noticeable.

Various factors that are present in the cold season can favor this process. Cold, lack of oxygen, poor nutrition and depressive moods cause the hair to end its growth phase at an early stage.

But a lack of nutrients or "mechanical damage" can also promote the hair loss process. Mechanical damage is caused in winter mainly by tight hats and tight combing of already stressed hair.

Vitamin D deficiency as a cause of hair loss

The days are shorter and the hair gets less sunlight is the main reason why parting occurs. In addition, there is the human hormone balance, which also reacts to changes in the length of the day. These hormonal fluctuations can cause hair loss.

It was discovered during numerous studies that patchy hair loss (alopecia areata) often correlates with a low vitamin D level. Further studies from 2016 in India made the importance of vitamin D for healthy hair growth even clearer. A significant vitamin D deficiency was found in 81.8%(!) of the subjects with "normal" hair loss.

Since we mainly produce our vitamin D needs with sunlight and there is a lack of intensive light in autumn and winter, vitamin D deficits from October to February can be a possible cause of hair loss.

Cold constricts the vessels , which can impair the (scalp) blood flow and thus the supply of nutrients to your hair roots.
