Hair Shedding in Fall: Why Autumn Asks the Follicle to Rest

Every October, the taiga where I grew up turns quiet in a particular way. The birch leaves let go before the wind even asks them to. The herds move lower, toward shelter, ahead of the cold that is coming whether anyone is ready or not. Nothing is dying in that quiet. Everything is simply choosing rest before the hard months arrive.

Growing up, brushing our hair was a daily event, not an occasional one. Whatever came loose in the brush never just went in the bin. We burned it. I was told why, as a child: left lying around, loose hair could trap a baby chick and tangle it, keeping it from lifting off when the rest of its group flew on. I did not question it then, and I still think of it every autumn, when my own brush holds a little more than it did in August. If you have noticed hair shedding in fall too, you are not imagining it, and you are very likely not losing your hair in any permanent sense. You are watching a cycle that has a season of its own.

Why Does Hair Shedding Increase in Fall?

Every hair on your head is moving through a cycle with several named stages. Anagen is the long growing phase, often lasting two to six years. Catagen is a short transition, a few weeks where the follicle begins to wind down. Telogen is the resting phase, roughly three months, where the hair is no longer growing but hasn't let go yet. Exogen is the release itself, the part you actually see on your brush.

Most people shed somewhere between fifty and a hundred hairs on an ordinary day without ever noticing. Several small studies on seasonal hair shedding have found that more follicles tend to shift into that resting telogen phase during the late summer months. Hair that enters rest in August or September is often released around twelve weeks later, which lands squarely in October and November. A temporary rise above your usual range in that window is not a sign that something has gone wrong. The timeline is simply doing what it was always going to do, a few months later.

Is It Stress, or Is It the Season? What Psychodermatology Tells Us

Psychodermatology looks at the two-way conversation between the mind and the skin, the scalp included. Cortisol, the hormone most closely tied to stress, is one of the signals researchers study when a follicle moves out of its growing phase sooner than it otherwise would, a pattern sometimes called telogen effluvium. Researchers are also looking at how stress affects inflammation around the follicle itself, a newer thread in the same field. None of this amounts to a diagnosis, and a pattern that lasts well beyond a few months is worth a conversation with a dermatologist rather than a guess from an article.

Autumn carries its own quiet weight. Shorter light. A return to tighter schedules. The emotional cost of a season closing, even a good one. None of this proves that fall itself causes shedding. It suggests something gentler: a body that has been carrying tension all year may show it first at the scalp, and autumn is often when that tension finally surfaces.

A Four-Season Way I Think About the Follicle

I did not learn hair science growing up. I learned seasons, and how a household plans around them. Inspired by that rhythm, the one nomadic life in Mongolia still follows across spring, summer, autumn, and winter, I have come to think about the follicle the same way.

Spring is new growth, the anagen phase in full motion, the way new grass pushes up the moment the ground softens. Summer is exposure, long days, the follicle doing its most visible work. Autumn is the turn, catagen giving way to telogen, the follicle choosing to rest before it has to. Winter is conservation, telogen held quietly, nothing wasted, nothing rushed, until spring asks the cycle to begin again.

This is the thinking behind how Dolgio treats the scalp itself, not as something to fix but as ground to tend in every season. The Nettle & Rosemary Shampoo Bar was built with that in mind: nettle to cleanse without stripping, rosemary to support the scalp alongside it, and French green clay in the lather, which gently absorbs excess oil without pulling the scalp dry.

What Actually Helps When Autumn Shedding Shows Up

No shampoo, bar or liquid, stops a follicle from resting on its own schedule. That part of the cycle isn't broken, so it isn't something to chase after fixing. What is worth tending is everything around it, the scalp environment the next cycle of hair will grow out of.

Wash in a way that cleans without stripping, so the scalp isn't carrying irritation on top of a normal seasonal shed. Spend an extra minute massaging the scalp while you wash, which simply feels better and keeps circulation moving. Stay consistent with one routine for a season rather than switching products every time more hair shows up on the brush, since switching often adds its own stress to a scalp that is already adjusting. Be gentle when hair is wet, when it is at its most fragile, and let it air dry when you can. And give the season its due. Three months of slightly heavier shedding, followed by a return to normal, is the pattern, not the exception.

Autumn is not asking for alarm. It is asking the follicle, and maybe you too, to rest before the next season of growth begins.

With warmth,
