What is Seasonal Hair Loss (seasonal shedding)?

Seasonal hair loss is a common phenomenon that affects many individuals worldwide. It is characterized by an increase in hair shedding during certain periods of the year, and while it is generally considered normal, it can sometimes indicate underlying health issues. In this blog post, we’ll delve deeper into the causes of seasonal hair loss and what you can do to address it.

So, how is it caused?

Hormonal changes:

As one of the most common causes of seasonal hair loss, fluctuations in hormones, such as those that occur during pregnancy or menopause, can cause hair loss. Moreover, changes in hormone levels during the fall and winter months can contribute to seasonal shedding. During these months, our bodies tend to produce more androgens, which can cause hair follicles to shrink, leading to hair loss.


The holiday season, exams, or any other stressful event can cause hair loss to worsen. When we experience stress, our bodies release cortisol, a hormone that can cause hair follicles to enter the resting phase, leading to hair loss.

Diet and Nutrition:

A poor diet or a deficiency in certain nutrients, such as iron or protein, can lead to hair loss. Eating a healthy, balanced diet that includes a variety of vitamins and minerals can help promote healthy hair growth.

Weather Conditions:

The cold, dry air of winter can strip the scalp of its natural oils, leading to dryness and flakiness, which can contribute to hair loss. Additionally, wearing hats or other headwear that can cause friction or sweating can also lead to hair loss.

Certain Medications:

For example, medications used to treat depression or high blood pressure can lead to hair loss. It’s important to talk to your doctor if you suspect that your medication is causing hair loss.

In conclusion, seasonal hair loss is a common occurrence that can be caused by a variety of factors, including hormonal changes, stress, diet, weather, and medication.
