What Causes Seasonal Hair Loss and Do You Need to Worry about It?

Autumn brings about a number of changes in our bodies – some are welcome, some are not. As your summer tan fades away and your body starts preparing for the winter, you may notice an increase in hair loss.

On average, we lose up to 125 hairs a day. But in October and November, the rate of hair loss grows. In most cases, this is natural and temporary and affects men and women equally. But what causes seasonal hair loss?

Put simply; your scalp needs to get rid of the extra hair that it grew in the summer.

What Happens in the Summer?

Hair growth happens in phases, and the life cycle of a hair is between two and six years. At any time, ten percent of your hair is in its so-called resting phase. This means that the follicle is completely dormant. Around three months after this phase begins, the hair falls out.

Women have a longer telogen (resting) phase in July, the hotest month of the summer. As a result of the heat, the affected hairs fall about 100 days later, when Autum arrives.

Seasonal hair loss happens in October and November, and to a lesser degree in the early summer. Summer hair loss is the result of some changes that happened in your hair during the spring months.

If your increased hair loss doesn’t fade away within a month or two, or if it feels really excessive, you should turn to an expert as soon as possible.

Our bodies have adapted to changes in the weather, and that is what causes seasonal hair loss. In the hottest months of the summer, your hair grows extra thick, and a lot of it goes into resting phase. It falls out three months later, causing a slight disruption in the usual patterns of your body. Seasonal hair loss is perfectly natural and usually doesn’t need any kind of treatment.
