Understanding the science behind increased hair loss during autumn — and what you can do about it.
If you’ve noticed more hair on your pillow, in the shower drain, or on your clothes as fall arrives, you’re not alone. Many people experience increased shedding during autumn, and while it can be unsettling, it’s usually a perfectly normal seasonal change.
At HairLoss.com, we’re here to help you understand why it happens — and how to support your hair during this transition.
Why Fall Shedding Happens: The Science Behind It
Just like our skin reacts to temperature, sunlight, and humidity changes, our hair also follows natural seasonal rhythms. Here are the main reasons shedding increases in fall:
1. Summer Stress on the Hair
During summer, your hair is exposed to:
-
UV rays
-
Heat
-
Chlorine and saltwater
-
Humidity
-
Sweat
All of these can weaken the hair shaft. As fall begins, the strands that were damaged during summer enter the shedding (telogen) phase, leading to noticeably more fall-out.
2. Your Body’s Seasonal Cycle
Research shows that humans shed more hair in late summer and early fall.
Why?
Because the body tends to hold onto more hair during summer to protect the scalp from UV rays — and once the season shifts, those extra strands are released.
This is similar to how many mammals experience a seasonal hair cycle.
3. Changes in Temperature and Humidity
As the weather cools:
-
The scalp can become drier
-
Hair becomes more brittle
-
The shift in humidity disrupts natural hydration
This can make weak strands fall out more easily.
4. Increased Stress Levels
Fall often brings new routines:
-
Back to school
-
End-of-year deadlines
-
Holidays approaching
Stress can amplify normal seasonal shedding, making the change feel more dramatic.
How Long Does Fall Shedding Last?
Seasonal shedding typically lasts 6 to 8 weeks.
If the shedding continues significantly beyond this window, or if you notice patchy hair loss, it may be related to other factors — and you may want to explore more targeted solutions.
How to Support Your Hair During Fall
Seasonal shedding is natural, but you can strengthen and protect your hair to keep it healthy and fuller-looking.

Your scalp is the foundation of your hair.

-

A healthy scalp grows stronger hair.
4. Reduce Heat and Chemical Stress
Give your hair a break during shedding season:
-
Use lower heat settings
-
Avoid overlapping color
-
Let hair air-dry when possible
The less stress on your hair, the stronger it stays.
5. Consider Nutritional Support
Your hair needs protein, iron, Vitamin D, and other nutrients to stay strong.
A balanced diet supports the natural growth cycle — and may reduce the severity of seasonal shedding.
When Should You Be Concerned?
Seasonal shedding is normal, but you should seek help if you notice:
-
Bald patches
-
Sudden, extreme shedding
-
Scalp irritation or inflammation
-
Shedding lasting more than 8–10 weeks
These can indicate factors beyond seasonal changes.
