Seasonal Hair Shedding: Why Late Winter Feels Worse

Every year, somewhere between the last cold snap and the first warm week, the drain starts looking alarming. Seasonal hair shedding is one of the most common things Australians ask a stylist about at the end of winter — and it is also one of the most misunderstood. The honest answer is that some of what you are seeing is a normal part of the hair cycle, some of it is not shedding at all, and a small part of it is worth having looked at properly.

This piece walks through what the research actually says about seasonal hair shedding, why late winter feels like the worst of it in Australia even though the science points elsewhere, and how to tell the difference between hair that has fallen out and hair that has snapped off. The two need completely different fixes.

What seasonal hair shedding actually is

Hair does not grow continuously. Each follicle runs its own independent cycle, and at any given moment your scalp is a mix of hairs at different stages. Seasonal hair shedding happens when an unusually large number of follicles move into the resting phase at roughly the same time, then release those hairs together a few months later.

The three phases, in plain English

• Anagen (growing): the active phase, lasting anywhere from two to six years. Around 85–90% of the hairs on a healthy scalp sit here at any one time.
• Catagen (transition): a short two-to-three week wind-down where the follicle detaches from its blood supply.
• Telogen (resting): roughly three months of dormancy. At the end of it, the old hair is pushed out by the new one growing underneath.

That three-month lag is the key to the whole thing. Whatever triggers a batch of follicles to shift into telogen, you will not see the result until about a season later. It is why shedding almost never lines up with the event that caused it, and why people so often blame the wrong month.

Does seasonal hair shedding really peak at the end of winter?

Here is where most blog posts overreach, so we will be straight about it: the published research on seasonal shedding points to autumn as the main peak, not the end of winter. Studies tracking telogen rates across a full year have consistently found the highest proportion of resting follicles in summer, which — with that three-month delay — produces the heaviest shedding in autumn. Translated to the Southern Hemisphere, that puts the big seasonal peak somewhere around March to May.

Some of the same work has also recorded a second, smaller rise in telogen hairs in spring. It is nowhere near as pronounced as the autumn one, but it is there, and in Australia that timing lands right at the end of winter and the first weeks of September.

So a genuine late-winter shed is possible. It is just usually not the biggest part of what people are noticing at this time of year.

What late winter actually does to Australian hair

The larger share of end-of-winter hair fall is not follicular at all — it is the accumulated result of three months of winter habits. None of these change your hair cycle, but all of them put more hair in your hands.

Hot showers and a dried-out scalp

Long, hot showers strip the scalp's lipid barrier. A barrier-compromised scalp gets tight, flaky and itchy, and an itchy scalp gets scratched — which loosens hairs that were already near the end of telogen and irritates the follicle opening. Turning the temperature down is genuinely one of the highest-return changes you can make.

Friction from hats, beanies and collars

Three months of wool against the hairline, plus scarves and coat collars dragging at the lengths, roughens the cuticle and creates weak points. We covered the mechanics of this in detail in our piece on winter hair damage from hats, beanies and friction. The hairs that come away from friction damage are broken, not shed.

Washing less often

People wash less in winter — it is cold, and hair holds a style longer. But the hairs released during telogen do not leave the scalp on their own; they are physically removed by washing and brushing. Stretch your wash from every second day to every fourth, and each wash releases roughly twice the hair. The daily rate has not changed. The batch size has.

Build-up at the roots

Dry shampoo, heavier winter conditioners, styling product and sebum all accumulate at the scalp. Build-up will not make your hair fall out, but it flattens the roots, so what regrowth you have reads as thinner than it is.

Shedding versus breakage: how to tell the difference

This is the single most useful thing you can learn about hair fall, because the two problems have almost nothing in common.

Look at the end of the hair

Pick up a fallen hair and look closely at one end under good light. A shed hair has a small, pale, slightly swollen bulb — the telogen root. That hair completed its cycle and left the follicle. A broken hair has no bulb at all: both ends look the same, blunt or frayed. Nothing has left your scalp. A strand has simply given way somewhere along its length.

Look at the length

Shed hairs are full length. If most of what you are finding is noticeably shorter than your hair, you are looking at breakage — and breakage is a mid-lengths and ends problem, not a follicle problem. Our companion piece on hair thinning versus breakage goes further into what people get wrong here.

Look at where it sits

Breakage tends to cluster: a halo of short flyaways around the crown, snapping where a ponytail sits, or a line across the hairline where a beanie has been rubbing. True seasonal shedding is diffuse. It comes off the whole head fairly evenly.

How much shedding is normal?

The commonly quoted figure is 50 to 100 hairs a day, and it is a reasonable rule of thumb — but it is an average across a day, not a count you can take from one wash. If you wash twice a week, a couple of hundred hairs in the shower is arithmetic, not a crisis.

What matters more than the number is the pattern over time. A seasonal shed ramps up over a few weeks, holds, and then settles within about six to eight weeks. Density recovers over the following few months as the new anagen hairs grow through. Shedding that keeps escalating past two or three months, or that comes with visible scalp showing through, is a different conversation.

What to do about it at home

Be realistic about what topical products can and cannot do. Nothing you apply to your scalp will override a hormonal, nutritional or medical cause. What a good routine can do is keep the scalp in decent condition, keep the hair you have from breaking, and stop you making the problem look worse than it is.

Treat the scalp as skin

A leave-in scalp treatment used consistently is more useful than an occasional intensive one. The King Brown Thickening Serum is a daily scalp serum built around Procapil and Trichogen, and the Floractive Blend Active Hair Tonic is a lighter option formulated for scalps that run oily. If you want the more clinical end of the shelf, La Biosthétique's Hairloss Control Scalp Lotion is a daily leave-in aimed specifically at density. There is more across the full Scalp Care collection.

Give any of them at least twelve weeks before you judge. That is one full telogen cycle — anything shorter and you are assessing hairs that were already committed before you started.

Strengthen the mid-lengths so less snaps off

If the test above told you that most of what you are losing is breakage, the fix is not a scalp product. It is protein and moisture through the lengths. A treatment mask like the Floractive Rosemary & Green Tea Mask is formulated for weakened, fragile hair and is an inexpensive place to start; the wider Treatments range covers heavier repair if winter has been rough on you. Getting the protein and moisture balance right matters more than the price of the jar.

Change how you brush

Most people brush hardest when they are most worried about losing hair, which is exactly backwards. Detangle from the ends upward, never from the roots down, and use something with give — an Unwritten Detangling Brush is designed to flex through knots rather than force them apart. Do not brush hair that is soaking wet; wet hair stretches and snaps far more easily than dry hair.

When to stop self-treating and get help

A seasonal shed is self-limiting. These are the signs that what you have is something else:

• Shedding that has not settled after three months.
• Scalp visibly showing through at the part line or temples.
• Loss in defined patches rather than evenly across the scalp.
• A scalp that is persistently sore, scaly, red or intensely itchy.
• Shedding alongside fatigue, unexplained weight change, or a recent illness, surgery, pregnancy or significant stress — all recognised triggers for telogen effluvium.
• A family history of pattern hair loss, particularly if the change is gradual rather than sudden.

Any of those is a GP or dermatologist conversation, not a shopping decision. Iron studies, thyroid function and vitamin D are the usual first things checked, and they are not something a shampoo can substitute for.

For everything short of that, a stylist is the fastest way to get a straight answer. A pro can look at your scalp and your ends in the same appointment and tell you within minutes whether you are shedding, breaking, or simply carrying three months of winter build-up.

Frequently Asked Questions

Is seasonal hair shedding permanent?

No. A seasonal shed releases hairs that had already finished their growth cycle, and the follicle begins a new anagen phase behind them. Density typically recovers over three to six months without any intervention.

Why does my hair shed more in the shower?

Because washing is when telogen hairs are physically dislodged. They had already detached; the shower is simply where you notice them. This is also why washing less often makes each individual wash look far more dramatic.

Should I wash my hair less to stop the shedding?

No — it will make it look worse, not better, and a scalp left unwashed for a week is more likely to become irritated. Washing does not cause shedding. It reveals it.

Can stress cause hair to shed?

Yes. Significant physical or emotional stress can push a large number of follicles into telogen at once, a condition called telogen effluvium. Because of the three-month lag, the shedding usually appears well after the stressful period has passed, which is why the connection is so often missed.

Do scalp serums actually work?

They can support scalp condition and the environment the follicle sits in, and some ingredients have reasonable evidence behind them. They will not reverse hormonal or medical hair loss. Treat them as maintenance, give them a full twelve weeks, and be sceptical of anything promising results in a fortnight.

Is it worth taking a supplement?

Only if you are actually deficient. Supplementing iron or zinc when your levels are already normal does nothing for hair and, in the case of iron, is not harmless. Get bloods done first.

Will a haircut help?

It will not change how much you shed, but if breakage is the real problem, removing the damaged ends stops the splits travelling further up the shaft — and hair that is not fraying at the ends looks and feels considerably denser.

The short version

Seasonal hair shedding is real, but the evidence puts its main peak in autumn rather than at the end of winter, with a smaller spring rise that lands about now. Most late-winter hair fall in Australia is a combination of that modest seasonal bump, three months of friction and heat damage showing up as breakage, and less frequent washing concentrating a normal daily loss into fewer, more alarming handfuls. Check the root of a fallen hair, look after the scalp as skin, brush more gently than instinct tells you to, and give any change a full twelve weeks. If it has not settled by then, get it looked at.
