How Long Does Postpartum Hair Loss Last? A Month by Month Guide
If you are asking how long does postpartum hair loss last, the reassuring answer is: usually a few months, and most people are back to their normal fullness by their baby's first birthday. Shedding tends to start two to four months after birth, peaks around four months, then slowly settles. This guide sets out that timeline month by month, explains why it happens, and shows when it is worth checking with a GP.

How long does postpartum hair loss last? For most people, noticeable shedding starts two to four months after giving birth, peaks at around four months, and eases over the following months. The American Academy of Dermatology says most women see their hair return to its normal fullness by their child's first birthday, and many sooner. If heavy shedding continues beyond a year, see a GP, because something else may be involved.
Key takeaways
- Postpartum shedding usually begins two to four months after birth and peaks around the four-month mark.
- The American Academy of Dermatology says most women regain normal fullness by their child's first birthday.
- It is a form of telogen effluvium: a shock to the system can push as many as 70% of growing hairs into the resting phase, according to DermNet.
- The NHS says losing 50 to 100 hairs a day is normal; postpartum shedding can be well above that for a while.
- See a GP if shedding lasts beyond a year, comes with tiredness or other symptoms, or leaves bald patches rather than general thinning.
How long does postpartum hair loss last, month by month?
Postpartum hair loss follows a fairly predictable pattern: little change in the first two months, shedding that starts between two and four months, a peak around four months, then a gradual easing through the second half of the first year. The American Academy of Dermatology says most women regain normal fullness by their child's first birthday.
| Time after birth | What usually happens |
|---|---|
| 0 to 2 months | Hair often still feels thick from pregnancy; little extra shedding |
| 2 to 4 months | Shedding starts; more hair in the brush, shower and on the pillow |
| Around 4 months | Shedding usually peaks; the hairline and temples can look thinner |
| 5 to 9 months | Shedding slows; short new hairs appear around the hairline |
| By 12 months | Most people are back to their usual fullness |
| Beyond 12 months | Ongoing heavy shedding is worth checking with a GP |
Everyone is a little different, and a second or third pregnancy can follow a slightly different pattern from the first. The timeline is a guide, not a deadline. What matters most is the direction of travel: shedding that is slowly easing is on track, even if it takes a few months longer than a friend's did.
Why does postpartum hair loss happen?
Postpartum hair loss happens because pregnancy holds more hairs in the growing phase, and after birth those hairs move into the resting and shedding phase together. The American Academy of Dermatology says the excessive shedding is caused by falling oestrogen levels after the baby is born.
Normally about nine in ten scalp hairs are growing at any time and the rest are resting before they fall. During pregnancy fewer hairs move into the resting phase, which is why many people notice thicker hair. After birth the balance swings back all at once. DermNet explains that after a shock to the system as many as 70% of growing hairs can be pushed into the resting phase, and lists childbirth as a typical trigger. Our guide to what causes telogen effluvium explains the wider pattern.
You are not losing more hair overall
Much of what falls out after birth is the hair you held on to during pregnancy. Across the whole pregnancy and postpartum period, most people end up close to where they started.
When does postpartum hair loss start?
Postpartum hair loss usually starts two to four months after giving birth rather than straight away, because hairs that move into the resting phase stay in the follicle for a few months before they fall. So shedding that begins around the three-month mark is right on time and not a sign that something has gone wrong.
This delay is why shedding often seems to come out of nowhere, just as life with a new baby is settling. Hair tends to come out in larger amounts when you wash or brush it, because loose resting hairs collect and come away together. A shower drain full of hair can look alarming, but it usually reflects several days of shedding at once.
When does postpartum shedding peak?
Postpartum shedding usually peaks around four months after birth, according to the American Academy of Dermatology. This is the point where most people feel most worried, with hair on the pillow, in the brush and in the shower, and where thinning at the hairline and temples is most visible.
The peak is also usually the turning point. Once the batch of hairs that paused during pregnancy has shed, the amount falling out each day starts to drop back towards the normal 50 to 100 hairs the NHS describes. Keeping a rough note of how much hair you see each wash can help you notice the trend, which is hard to judge from one bad day.

When does postpartum hair loss stop?
Postpartum hair loss usually stops, or at least settles back to normal levels, somewhere between six and twelve months after birth, and most people are back to their usual fullness by their baby's first birthday. Short, wispy new hairs around the hairline are a good sign that growth has resumed.
Those baby hairs can stick up and look frizzy while they grow, which is normal. They grow at around a centimetre a month, so it takes a while for them to blend with the rest of your hair. A few face-framing layers or a soft fringe can help them look deliberate. Our guide to postpartum hair loss and what helps covers the whole topic in more depth.
Is it postpartum shedding, hair breakage or hair loss?
Postpartum shedding, hair breakage and hair loss are different things, and telling them apart helps you know whether to wait, change your routine or see a GP. Hair shedding is whole hairs falling out root and all, often with a small white bulb at the end; postpartum shedding is this kind, and it is temporary.
Hair breakage is the hair fibre snapping part way along, leaving short pieces with no bulb. New parents often have more of it than usual, from tight ponytails, rushed brushing and hair tugged by little hands. Hair loss in the medical sense means follicles producing less hair over time. DermNet notes that postpartum shedding can resolve after a few months or sometimes reveal female pattern hair loss, which is why shedding that does not settle is worth checking.
| Type | What you see | What to do |
|---|---|---|
| Postpartum shedding | Whole hairs with a bulb, all over the scalp, worst around 4 months | Be gentle and give it time; usually settles by 12 months |
| Breakage | Short snapped pieces, split ends, frizz | Loose styles, gentle detangling, conditioner every wash |
| Patchy or ongoing loss | Bald patches, a widening parting, loss after a year | See a GP |
How should you care for your hair while postpartum hair loss lasts?
You should care for your hair gently while postpartum hair loss lasts: wash with a mild shampoo, condition every time, detangle with a wide-tooth comb, and avoid tight styles and heavy heat. Nothing speeds up the hair cycle, but a kind routine limits breakage so the hair you keep looks as full as possible.
The American Academy of Dermatology suggests volumising shampoo and a light conditioner, and avoiding heavy conditioning products that can weigh fine hair down. Tie hair back loosely with a soft band or a claw clip rather than a tight ponytail, which pulls on the fragile hairline. Keep hot tools on a low setting and use them less often. If washing feels upsetting because of the hair you see, remember that washing does not cause shedding; it just collects the loose hairs. Our tips on losing less hair in the shower may help.

Does diet or breastfeeding affect how long postpartum hair loss lasts?
Diet and general health can affect how long postpartum hair loss lasts, because low iron and other nutritional gaps are known triggers for extra shedding. DermNet lists iron deficiency among the causes of telogen effluvium, and blood loss at birth can leave some people low in iron.
The NHS lists tiredness, shortness of breath and heart palpitations among the symptoms of iron deficiency anaemia, and a GP can check your iron with a simple blood test. Eating regular meals with protein, iron-rich foods and fruit and vegetables supports your recovery generally. Breastfeeding is not usually singled out as a cause of postpartum shedding, but it does increase your nutritional needs, so do not skip meals. Speak to your GP, midwife or health visitor before starting any supplement while breastfeeding.
Which hairstyles hide postpartum shedding?
The hairstyles that best hide postpartum shedding are ones that add volume at the crown and soften the hairline: a side part, face-framing layers, a soft fringe, and loose waves. A shorter, layered cut can also make hair look thicker while shedding settles.
Moving your parting to the other side instantly adds lift at the root. A soft fringe or curtain bangs can cover thinner temples. Dry shampoo at the roots gives grip and volume on busy days. Avoid slicked-back or very tight styles, which show the hairline and pull on it at the same time.
When should you see a GP about postpartum hair loss?
You should see a GP about postpartum hair loss if heavy shedding lasts more than a year, if you notice bald patches rather than general thinning, or if it comes with other symptoms such as extreme tiredness, feeling cold, weight changes or low mood. The American Academy of Dermatology says that if hair does not regain its normal fullness after a year, something else may be causing it.
Thyroid changes after pregnancy and low iron are both worth ruling out, and your GP can arrange simple blood tests.

The NHS says 50 to 100 hairs a day is normal. Postpartum shedding can be noticeably more than that for a few months before settling.
Does breastfeeding make postpartum hair loss worse?
Breastfeeding is not usually singled out as a cause, but it raises your nutritional needs. Eat regularly and ask your GP before taking supplements.
Can I stop postpartum hair loss?
You cannot stop the hair cycle resetting, but gentle care limits breakage so hair looks fuller while shedding settles.
Will my hair grow back after postpartum shedding?
Yes, for most people. Short new hairs around the hairline usually appear within a few months and grow at around a centimetre a month.
What is the bottom line on how long does postpartum hair loss last?
The bottom line on how long does postpartum hair loss last is that it is temporary for most people: shedding starts two to four months after birth, peaks around four months and settles by the first birthday.
