Everything you need to know about seasonal hair loss

It is not uncommon to experience hair loss with the arrival of autumn and spring. In this case, we talk about seasonal hair loss. Where does it come from and how should you react? Let's take a look.



Change of season and reactional hair loss: what are the links?

The natural life cycle of hair includes three well-defined phases (anagen, catagen and telogen) during which the hair grows, regresses and falls out. Thus, it is perfectly normal to lose between 50 and 100 hairs per day without even noticing it. However, when autumn arrives, some people experience more significant hair loss. What causes seasonal hair loss? The obvious lack of light in autumn affects hormones and vitamin D production in the body. These changes have a direct impact on hair growth and cause hair loss. This reactionary hair loss is scientifically called "acute telogen effluvium". It is the most common form of diffuse hair loss, especially in women. Seasonal hair loss in autumn can also be promoted by the stress and accumulated fatigue that usually occurs at this time. Fatigue-related hair loss is another cause of reactional hair loss.

How long does seasonal hair loss last?

Seasonal hair loss lasts no longer than 6 months. It is a completely reversible type of reactional hair loss. The first signs of regrowth are observed within 3 to 6 months and it may take 12 to 18 months for the hair to return to its original state in some people.

Seasonal hair loss: how to fight it

Seasonal hair loss can affect anyone, even if you've never been affected before. There are some simple everyday things you can do to help stop it.

  • Pay special attention to the hair care products you use.
  • Choose shampoo formulas that are gentle and respectful of the hair and scalp. Favor loose and detached hairstyles rather than tight ties and braids that weaken the hair fiber.
  • Take a closer look at the composition of your food. Vitamins and minerals play an essential role in the life cycle of normal hair, particularly in the renewal and rapid multiplication of the cells that form the hair. They must be provided in sufficient quantities to the scalp to nourish it and stimulate hair growth. At the change of season, to prevent seasonal hair loss, dietary supplements containing B vitamins, sulfur amino acids, zinc, iron and selenium can be a good complementary option to the hair care routine.
