Seasonal hair loss in autumn: how long is it normal?
8 min read Life stages Updated 5 October 2026 By Anna Sophie Schulenburg
Hair loss in autumn is normal in most cases and passes on its own: some of your hairs switch into their resting phase in high summer and come loose two to three months later, between September and November. So keep your care as it is, take a photo of your parting in daylight today and repeat it every four weeks. If the parting stays the same width in the photos and your brush collects fewer hairs again by December, it was the autumn phase.
A tangle in the plughole after washing, long hairs clinging to your dark jumper, a few more on the pillow in the morning. It's alarming, especially in the year you notice the autumn wave for the first time.
Why more hair falls out in autumn
Each hair grows for several years, goes through a short transition phase and then rests for about three months. At the end of the resting phase the root pushes up a new hair and the old one falls out. Because every hair runs on its own clock, roughly one in ten is resting at any given moment. That adds up to the 50 to 100 hairs you lose on an ordinary day.
Studies in Europe that analysed hair samples across the whole year found the highest share of resting hairs in high summer. Add the three months of rest and the shedding lands in autumn. Why summer sends more hairs into a pause is still unclear. Daylight and hormones are discussed; neither has been proven. How strong the wave is differs from woman to woman. If you notice nothing in autumn, that's just as normal.
If you wash only every two to three days, the loosened hairs collect in your hair in between and come out all at once in the shower. A tangle of 150 or 200 hairs after three days therefore works out at the same amount as 50 to 70 a day.
How many hairs a day are still normal in autumn can't be pinned to one number, because the amount depends on density, length and how often you wash. More telling is whether your parting stays the same width in the photos and whether the amount drops again from December.
Autumn shedding or something else? The self-check
For this test, look closely at a few shed hairs from your brush and compare your current parting photo with one from early summer, if you have it.
| What you notice | Fits the autumn phase | Points to another cause |
|---|---|---|
| When it started | September to November | In another season, or already since spring |
| Where hair is missing | Evenly all over the head | Round bald patches, gaps at the temples, a wider parting |
| The end of the hair | A small white bulb at the root | No bulb, the hair has snapped along its length |
| Your scalp | Calm, looks the same as always | Red, flaky, itchy, burning or sore |
| The months before | Nothing unusual | Fever, giving birth, a diet, a new medication, a very demanding time |
| How long it lasts | A few weeks, easing off in December | More than three months, or beyond January |
If the white bulb is missing at the end, the hair has snapped along its length. Breakage needs different care from shedding. With a handful of hairs from your brush you can check whether it's breakage or hair loss.
If most rows fit the middle column, the free hair analysis asks about hair thickness, how your scalp feels and your care one by one, and suggests a routine for these weeks.
How long does autumn hair shedding last?
Usually a few weeks. If the shedding goes on for more than three months or past January, it no longer fits the autumn pattern. The overview below shows what you can see in which month.
| Period | What happens at the root | What you see |
|---|---|---|
| July and August | More hairs switch into the resting phase | Nothing yet, the hair still sits firmly |
| September to November | The resting hairs come loose | More hair in the brush, the plughole and on the pillow |
| December and January | The wave fades out | The amount after washing drops back to your usual level |
| February to April | The new hairs grow about one centimetre a month | Short hairs sticking up along the hairline and in the parting |
The short hairs in spring are a good sign. They show that the roots keep working and are replacing the hairs that fell out.
A low-effort routine for the weeks with more hair in the brush
You don't need new products during this time. The aim is to avoid breaking the hair you have and to style the roots so they look full. The amounts are for shoulder-length hair.
Step 1 — Wash as usual. Stick to your normal rhythm. Washing more often loosens no extra hairs; it only rinses out the ones that are already loose. Lather a hazelnut-sized amount of shampoo in your palm, spread it over the scalp and massage for 30 to 60 seconds with your fingertips. Lukewarm water is enough.
Step 2 — Condition and detangle the lengths. Conditioner goes on from ear level down only and stays on for two minutes. Use that time to detangle with a wide-tooth comb, ends first, then working upwards a hand's width at a time. That way you won't pull out hairs that are still firmly anchored.
Step 3 — Dry with care and tie up loosely. Squeeze your hair in the towel instead of rubbing it. Blow-dry on a medium setting, 15 cm away. For a ponytail, use a spiral hair tie and place it somewhere different each day, so the pull at the hairline doesn't always land on the same hairs.
Step 4 — Lift the roots. Blow-dry the first few centimetres on top of your head against the direction of growth, and shift your parting by a finger's width every few days. That gives more lift at the roots, and a fresh parting lets less scalp show through.
From October, dry central heating joins in. The lengths turn more brittle and go static under a hat, so it's worth planning care against heated air and static hair at the same time.
If you use MONAT: Revive™ Shampoo and Revive™ Conditioner are designed for fine, flat hair and are meant to leave the roots unweighted. They change nothing at the root, and the autumn phase won't end any sooner with them. If your scalp feels tight during the heating season, spread a few drops of MONAT Scalp Comfort™ Rebalancing Serum along three or four partings and leave it in; if it stings, stop using it.
What doesn't help with autumn hair loss
- Washing less often holds no hair in place. The loosened hairs all come out at the next wash, and the tangle in the plughole looks even bigger.
- Getting your hair cut shorter changes nothing at the root. Shorter hairs stand out less in the plughole, which is why it feels better. Still, nothing speaks against a new cut if you wanted one anyway.
- Biotin and hair vitamins only help if you're actually short of something. High-dose biotin can also distort lab results, including thyroid values. Tell your doctor before a blood test.
- Rosemary oil and caffeine shampoo get recommended a lot in autumn. Because the wave subsides on its own, you can't tell from your hair whether a product did anything. Behind the recommendation stand a few small studies on rosemary oil for hair loss, and none of them looked at autumn.
- Vigorous brushing “for circulation” tends to pull out hairs that would otherwise have held. Massage your scalp with your fingertips when you wash instead.
When autumn hair loss needs a doctor
Round bald patches belong with a dermatologist. The usual cause is alopecia areata, an inflammatory form of hair loss, and there are treatments for it that only a doctor can start. Book an appointment, with your GP first if you like, also if
- the shedding lasts longer than three months or carries on undiminished in January,
- your parting gets wider from month to month in the photos, or gaps appear at the temples,
- your scalp is red, flaky, weeping or painful,
- at the same time you feel unusually tired, feel the cold a lot, gain or lose weight, or your cycle changes,
- you started a new medication in the three months before.
Ask there whether ferritin (your iron stores), TSH (the thyroid) and a full blood count make sense. Iron deficiency and a thyroid that has gone out of balance are among the causes that are easy to check.
If you had a fever, an operation or a very stressful time two to three months before the shedding began, that is the likely trigger rather than autumn. This kind of hair shedding after stress or fever starts with the same delay and usually settles within a few months. After giving birth, postpartum hair loss usually begins two to four months later, whatever the season. If your hair seems finer overall after winter than it used to, the care for thinning hair is the better fit.
What care can do
Support cleansing, conditioning, manageability, shine, frizz control, protection from avoidable breakage and a fuller-looking appearance, depending on the product and its substantiated claims.
What it cannot do
Diagnose disease, correct hormonal causes, create new follicles or permanently fuse fully split hair ends.
Quick questions
Do men shed more hair in autumn too?
Yes. The hair cycle works the same way in men, and the seasonal studies included both women and men. In men, hereditary hair loss can also be behind it, and that can begin in any season. A receding hairline and thinning on top therefore don't fit the autumn wave.
Does autumn hair loss come back every year?
Yes, the pattern can repeat every year. Once you have tracked the wave with photos, you'll recognise it the following year and won't have to puzzle over it again.
Is there more hair loss in spring too?
Yes, some women have a smaller second wave in spring. The studies on it are inconsistent. The self-check and the warning signs in this article apply to the spring wave just the same.
Does coloured or bleached hair fall out more in autumn?
No. Colour and bleach change the hair fibre; they leave the hair cycle at the root alone. Bleached hair does break more easily, though, and snapped pieces in the brush look like shed hairs at first glance.
