Postpartum Hair Loss: Causes, Timeline & What to Expect

You're in the shower, running a hand through your hair, when you notice something that stops you cold: a clump of strands circling the drain that definitely wasn't there a few months ago. Or maybe your hairbrush has been suspiciously full lately.

Take a breath. What you're noticing is one of the most common, least talked-about parts of postpartum recovery, and you are not imagining it. The good news is that postpartum hair loss resolves for nearly everyone who experiences it, and understanding why it happens tends to make the whole thing feel a lot less alarming.

This guide walks through what postpartum hair loss actually is, why it happens, how much shedding is considered normal, and when it's worth a call to your healthcare provider. (If you'd like the bigger picture of your fourth-trimester recovery, our guide to postpartum care covers everything from physical healing to emotional well-being.)

What Is Postpartum Hair Loss?

Postpartum hair loss, sometimes called postpartum hair shedding, is the noticeable increase in hair shedding that many new mothers experience in the months following childbirth. Your body is adjusting to enormous hormonal shifts during this period, and hair is simply one more place those changes show up.

You might also see it described as hair loss after giving birth, post partum hair loss, or postnatal hair loss — different phrasing for the same experience, and a far more common one than most people realize going in.

According to the National Health Service (NHS), it's common for women to notice more hair falling out than usual in the months after giving birth. What's happening is a temporary shift in your hair's growth cycle (sometimes called telogen effluvium): more hairs than usual move into their resting phase at the same time, instead of on their usual staggered schedule, and that catch-up is what shows up in the shower or on your hairbrush. We'll walk through the specific timeline — when it tends to start, peak, and ease off — in the "How Much Hair Loss Is Normal?" section below.

Postpartum hair shedding is not a sign that something has gone wrong. It's a normal, temporary side effect of your hair cycle catching up with itself after pregnancy paused it for nine months.

Why Does Postpartum Hair Loss Happen?

During pregnancy, rising hormone levels do your hair a favor: more of your follicles stay in the growing phase for longer than they normally would, which is a big part of why so many people notice thicker, fuller-feeling hair while pregnant. Pregnancy hormones essentially put the shedding phase on hold for a while.

After delivery, estrogen drops sharply, and many of those follicles shift into the resting phase around the same time instead of on their usual staggered schedule. According to StatPearls, this kind of physiologic-stress-triggered shift is a well-documented trigger for this type of hair loss, and the postpartum drop in estrogen is among its most common causes.

In a normal, non-shedding scalp, about 85% of hairs are in the growing phase and 15% are in the resting phase at any given time. Postpartum hormone changes temporarily tip that balance, which is why hair that felt extra thick during pregnancy can suddenly seem to be thinning a few months after your baby arrives. The total amount of hair isn't actually changing. Shedding that would normally spread out over many months is simply happening in a shorter window instead.

How Much Postpartum Hair Shedding Is Normal?

Everyone sheds hair every day, postpartum or not. On an average day, most people lose up to around 100 hairs from their scalp, and those hairs typically grow back without anyone noticing. Postpartum shedding feels different because it's concentrated: more hair falling out within a shorter window, instead of spread evenly across the year. For most people, that looks like noticeably more hair than usual coming out during washing or brushing, along with some visible thinning around the hairline or part, rather than sudden bald spots.

Research gives a fairly consistent picture of the timeline. One study that surveyed postpartum women found that about 9 in 10 noticed at least some hair loss, with shedding typically starting around month 3 after birth, peaking around month 5, and tapering off by around month 8. That means the active shedding episode itself usually runs about five months from start to finish, which lines up with the general clinical definition of this type of hair loss (acute telogen effluvium) resolving in under six months. In other words, even toward the later end of that range, this is still considered a normal, expected part of recovery rather than a warning sign on its own. Everyone's timeline looks a little different, but if you're noticing shedding anywhere in that general window, you're in very good company, not the exception.

When Postpartum Hair Loss Goes Beyond Normal

Most postpartum hair loss is the plain, run-of-the-mill shedding described above, and staying within the general timeline covered in the section above isn't a red flag on its own, even if you're a few months in and still shedding heavily.

That said, it's worth taking hair loss seriously rather than automatically assuming it's "just" standard postpartum shedding. Loop in a healthcare provider if shedding doesn't start improving as expected, shows up as distinct bald patches rather than general thinning, feels unusually severe, or shows up alongside other symptoms things like ongoing fatigue that feels deeper than typical new-parent tiredness, unusually dry skin, or hair and nails that have gotten noticeably more brittle. These are recognized early signs of both an underactive thyroid and iron deficiency or anemia, and either condition can drive hair loss on its own and is worth ruling out rather than assuming everything is hormonal. Persistent hair loss can also come from other causes layered on top of ordinary postpartum shedding, like a different hair or scalp condition, which is part of why an unusual or prolonged pattern is worth having a professional take a look at rather than self-diagnosing. If your provider suspects something beyond typical postpartum shedding, they may suggest bloodwork, which could include a complete blood count along with thyroid and iron checks but what's actually needed depends on your specific symptoms and history, so let their judgment guide that rather than requesting a fixed panel on your own.

If the emotional side of this is hitting harder than you expected, that's completely normal too, and you're far from alone: the same study mentioned above found that about 3 in 4 women who noticed postpartum hair loss felt anxious or stressed about it specifically. So if you've been quietly worrying about your hair, know that most people going through this feel exactly the same way. And if that worry starts to feel bigger than the hair loss itself, or spills into other parts of your day, it's okay to reach out for support, our guide to postpartum anxiety walks through what that can look like and when it's time to talk to someone.

Is Postpartum Hair Loss Permanent?

Postpartum hair loss is temporary. It's a dip while your hormones settle into their new baseline, not a preview of what your hair looks like from here on out. As the timeline above suggests, most women notice their shedding ease up well before their baby's first birthday, though exactly how quickly it feels back to normal varies from person to person. It's completely fair to feel impatient while you wait it out.

In the meantime, gentle hair care and solid overall nutrition can make the process feel more manageable, even if they don't speed up the biology underneath it. Being gentle with wet hair, reaching for a wide-tooth comb, skipping tight ponytails and heavy heat styling where you can, and giving yourself grace on the days shedding feels extra noticeable can all make the day-to-day experience a little kinder, even though none of it shortens the hormonal timeline your body is working through. 

If you'd like a little extra support while you wait it out, our Postpartum Hair & Energy Care Kit is built for exactly this stretch, or you can explore Priorin Hair Loss Supplements and Priorin Liquid Hair Support on their own. As with any new supplement, it's worth checking with your healthcare provider first, especially if you're breastfeeding.

FAQs

Does Everyone Get Postpartum Hair Loss?

Almost: one study found that about 9 in 10 postpartum women reported at least some hair loss, making it the norm rather than the exception. If you haven't noticed much shedding yourself, count yourself lucky rather than wondering if something's different about your recovery.

Why Does Hair Loss Happen After Birth Instead of During Pregnancy?

Pregnancy hormones, especially estrogen, keep more hair follicles in their active growing phase than usual. Once you give birth and those hormone levels drop, those follicles shift into their resting phase together instead of on their usual staggered schedule, which is why the shedding shows up after delivery rather than during pregnancy itself.

When Do You Stop Losing Hair Postpartum?

That timeline tracks the research above: shedding tends to taper off by around month 8, after peaking around month 5. Everyone's timeline looks a little different, but if you're still shedding noticeably well past your baby's first birthday, that's a good reason to check in with your healthcare provider.

Can Hair Care Habits Make a Difference?

Gentle hair care, like minimizing heat styling, using a wide-tooth comb on wet hair, and avoiding tight hairstyles that pull at the scalp, can make shedding feel more manageable day to day. These habits won't change the underlying hormonal timeline, but they can reduce extra breakage while your body works through it.

Could Thyroid or Iron Issues Be Behind My Hair Loss?

Sometimes, and it's worth asking rather than assuming especially if the shedding comes with ongoing fatigue, dry skin, or hair and nails that seem more brittle than usual, all recognized signs of an underactive thyroid or iron deficiency/anemia, per MedlinePlus. Either condition can cause a more persistent pattern of hair loss that doesn't resolve on the same timeline as typical postpartum shedding, alongside other possible causes a dermatologist can help rule in or out. If your provider suspects something beyond typical postpartum shedding, they may suggest bloodwork, such as a complete blood count along with thyroid and iron checks, tailored to your specific symptoms.
