The Short Answer
Postpartum hair loss usually lasts a few months. Shedding typically starts two to four months after giving birth, peaks around month four, and slows between six and twelve months postpartum. Most women see their hair return to its usual fullness by their baby's first birthday. Shedding that continues well beyond a year is worth checking with a doctor.

How long does postpartum hair loss last? For most women, the heavy shedding lasts a few months and the whole episode is over by the time the baby turns one. It usually starts two to four months after giving birth, peaks around four months, and then slowly winds down. Knowing that timeline will not make the handfuls of hair in the shower any less startling, but it should make them less frightening.
Postpartum shedding is extremely common and almost always temporary. It is not a sign that you are losing your hair for good, that you are lacking something, or that you did anything wrong. It is the hair growth cycle catching up after pregnancy, when hormones held many hairs in their growth phase for longer than usual.
Below, we walk through what causes it, the month-by-month timeline, what can make it last longer, what is safe to use while breastfeeding, and when it is worth seeing a doctor. If you want products that help your hair look fuller in the meantime, our guide to the best postpartum hair loss products focuses on gentle, breastfeeding-friendly options.
Why Postpartum Hair Loss Happens
Normally, a small share of your hair is always in telogen, the resting phase, and sheds each day as part of a steady cycle. During pregnancy, high levels of hormones, including estrogen, keep more hairs in anagen, the growth phase, for longer than usual. Fewer hairs move into rest, so many women notice their hair feels thicker and sheds less while they are pregnant.
After delivery, those hormone levels fall quickly. The extra hairs that were held in the growth phase move into the resting phase at about the same time. The resting phase lasts roughly three months, and when it ends, those hairs shed together. That is why the shedding arrives a couple of months after birth rather than immediately.
The follicles are not damaged.
Doctors call this postpartum telogen effluvium. It is the same type of shedding that can follow a high fever, surgery or a major shock, and in this case the trigger is the hormonal shift of giving birth. The follicles are not damaged. They release their old hairs and start growing new ones.
In a sense, the shedding is the hair you held on to during pregnancy finally being let go, all in a short window. That can make it feel like far more than you would ever normally lose, even though the overall picture is a return to your usual cycle.
The Postpartum Hair Loss Timeline, Month by Month
In the first two months after birth, most women notice little change. Hair that grew during pregnancy is still in place, and the hairs that have moved into the resting phase are still anchored. This is a good time to keep your routine gentle and, if your doctor advises it, to continue a prenatal or postnatal vitamin.
Between about two and four months, shedding begins and builds. Hair comes out evenly across the scalp, often in noticeable amounts in the shower and on the brush. Around four months, it tends to peak, and many women notice thinner temples or a more visible part. This is usually the most distressing stage, and it is the one most women search about.
Between six and twelve months, shedding slows. You will often see short, fine hairs growing along the hairline and temples. These regrowth hairs can stick up and look frizzy for a while, but they are a good sign that the cycle has reset.
By around twelve months, most women's shedding has returned to normal, and density is back to where it was before pregnancy. Length takes longer: hair grows only about a centimeter a month, so the shorter regrowth along your hairline may take another year or more to blend in with the rest of your hair.
| What You May Notice | What Helps | |
|---|---|---|
| Months 0-2 | Little change; pregnancy hair still in place | Gentle routine; keep prenatal or postnatal vitamin if advised |
| Months 2-4 | Shedding begins and builds | Volumizing shampoo, wide-tooth comb |
| Months 4-6 | Peak shedding, thin temples | Root powder, loose updos |
| Months 6-12 | Shedding slows; short regrowth appears | Light styling to tame regrowth |
| Past 12 months | Most women back to baseline | See a doctor if still shedding |
How Much Postpartum Shedding Is Normal?
Outside pregnancy, losing roughly 50 to 100 hairs a day is normal. During postpartum shedding, many women lose noticeably more than that for a period of weeks. Because so many hairs move into the resting phase at once, clumps in the drain and hair on your pillow are common, and they are part of the expected process.
The pattern matters more than the amount. Postpartum shedding is diffuse, meaning it comes out evenly across the scalp. The temples and the hairline often look thinnest, simply because there is less hair there to begin with. What it should not do is leave smooth, distinct bald patches.
The pattern matters more than the amount.
Wash days will look the worst. Hairs that have been released often stay tangled among the rest of your hair until you wash, condition or brush, so a single shower can release several days' worth at once. Skipping washes to avoid seeing it only means more comes out next time.
How much any one woman sheds varies. Some notice only a mild increase; others see dramatic thinning at the temples. The experience can also differ from one pregnancy to the next. Neither a light shed nor a heavy one predicts that something is wrong, as long as it follows the usual timeline and recovers.
What Can Make Postpartum Hair Loss Last Longer
Postpartum shedding often overlaps with other things that affect hair, and those can prolong it or make it heavier. Low iron is a common one. Blood loss at delivery and the demands of pregnancy can leave iron stores low, and low iron is itself linked to shedding.
Thyroid changes are another. Some women develop postpartum thyroiditis, an inflammation of the thyroid that can occur in the first year after birth. It can cause fatigue, palpitations, feeling hot or cold, weight change and mood changes, and it can affect hair. A simple blood test can check thyroid function.
Low iron is a common one.
Low vitamin D, very little sleep, ongoing stress and not eating enough can all add to the picture. None of these are unusual in the months after having a baby, which is why it is worth raising hair shedding at your postpartum checkup, especially if it seems severe.
Postpartum shedding can also unmask female pattern hair loss in women who were already predisposed. If shedding stops but your part keeps widening in a pattern, rather than filling back in evenly, that suggests pattern thinning, which needs a different approach. Breastfeeding is not thought to cause postpartum shedding, though some women find the timing shifts while nursing or after weaning.

The best everyday upgrade during postpartum shedding: fuller-looking hair with no treatment risk.
What Is Safe to Use While Breastfeeding
The most important point is what to avoid. Minoxidil, the main over-the-counter hair regrowth treatment, is not recommended during pregnancy or breastfeeding, and you should not use it while nursing unless your doctor specifically approves it. It is also not needed for postpartum shedding, which resolves on its own.
Be careful with hair supplements too. Many branded hair formulas contain botanicals or high doses of vitamins that have not been studied in breastfeeding women. Check every supplement with your doctor, including those marketed for hair, skin and nails. A postnatal multivitamin recommended by your doctor is a more appropriate choice than a separate hair supplement.
Be careful with hair supplements too.
Cosmetic products are generally a safer way to help. A volumizing shampoo such as Living Proof Full, our top postpartum pick, can make fine, flat hair look fuller between washes. Root touch-up powders can disguise thinning temples and a visible part. These do not change the shedding, but they can make it less obvious.
If you plan to color, bleach or chemically straighten your hair, it is reasonable to ask your doctor or pharmacist, and many women choose gentler options in the early months. Fragile, shedding hair is also more prone to damage, so going easy on strong chemical treatments is a good idea for your hair regardless.
How to Look After Your Hair While It Recovers
Nothing you buy can stop the hairs that have already been released from falling. What you can do is protect the hair you have from unnecessary breakage, which makes thin hair look thinner still. Detangle with a wide-tooth comb or a soft detangling brush, starting at the ends, ideally with conditioner in.
Avoid tight ponytails, buns and braids, which pull on fragile hair and can add traction damage at the hairline. Claw clips and loose styles are kinder. Keep heat styling to a minimum and use a heat protectant when you do. Pat hair dry rather than rubbing it with a towel.
Nothing you buy can stop the hairs that have already been released from falling.
Choose products that lift rather than weigh down. A lightweight, volumizing shampoo and a conditioner applied only to the lengths help fine hair look fuller. Dry shampoo is useful for low-sleep weeks when washing is not realistic, and it adds some texture at the roots.
Many women find a new haircut helps. A shorter cut or long layers can make thinning less obvious and make it easier to style the short regrowth along the hairline when it appears. It also makes daily care quicker at a time when every minute counts.
Dealing With Postpartum Regrowth Hairs
Once the shedding eases, a new and sometimes unexpected phase begins: regrowth. Short, fine hairs start appearing along the hairline, at the temples and around the part. Because they all started growing at roughly the same time, they tend to be the same length, which can create a visible fringe of short hairs that sticks up or frizzes.
These hairs are a welcome sign. They mean the follicles that shed have started new growth cycles, exactly as expected. They are often finer and softer at first and gradually feel more like the rest of your hair as they lengthen.
These hairs are a welcome sign.
Styling them is mostly about patience. A small amount of light styling cream or gel, smoothed down with a soft brush or a clean toothbrush, can help them lie flatter. Some women prefer to lean into them with a side part, face-framing layers or a short fringe that blends the new growth with the rest of their hair.
Avoid fighting them with lots of heat or tight styles that pull them back. Short new hairs are fragile, and constant tension at the hairline can damage the very hairs you are waiting for. Within several months they will be long enough to tuck back or blend in.
When to See a Doctor About Postpartum Hair Loss
Most postpartum shedding needs nothing more than time, but some signs are worth getting checked. See a doctor if shedding is still heavy well past your baby's first birthday, if your hair is not filling back in, or if your part continues to widen in a pattern.
Get checked sooner if you notice smooth, round bald patches, which can point to alopecia areata, or if your scalp is red, scaly, itchy or painful. These are not typical of postpartum telogen effluvium and may need specific treatment.
Other symptoms matter too. Fatigue beyond what you would expect with a newborn, palpitations, feeling unusually hot or cold, weight change, or very heavy periods can point to thyroid problems or iron deficiency. Both are common after birth and are easy to test for with a blood test.
If your shedding has stopped but you want help regrowing density after you finish breastfeeding, a doctor or dermatologist can discuss options such as minoxidil. Our guide to the best minoxidil for women covers the foam and solution options for when that time comes.
Frequently Asked Questions
When does postpartum hair loss start?
Usually two to four months after giving birth. The drop in pregnancy hormones moves many hairs into the resting phase at once, and that phase lasts roughly three months before the hairs shed. That is why shedding starts a while after delivery rather than right away.
When does postpartum hair loss peak?
It tends to peak around four months after birth, when shedding in the shower and on the brush can look startling and the temples often look thinnest. After the peak, it gradually slows, and most women notice it easing between six and twelve months postpartum.
Will my hair go back to normal after postpartum hair loss?
For most women, yes. The follicles are not damaged, and hair usually returns to its normal fullness by around the baby's first birthday. Regrowing length takes longer. If thinning continues past a year or your part keeps widening, see a doctor, as pattern hair loss can sometimes emerge.
Does breastfeeding make postpartum hair loss worse?
Breastfeeding is not thought to cause postpartum shedding, which is driven by the hormonal drop after birth. Some women find the timing shifts while nursing or after weaning. Breastfeeding does increase nutritional needs, so ask your doctor whether a postnatal vitamin or iron and vitamin D tests make sense.
Can I stop postpartum hair loss?
Not really. The hairs that shed were released months earlier by the hormonal change after birth, so no product can hold them in place. What helps is gentle care to reduce breakage, cosmetic products to make hair look fuller, and checking for low iron or thyroid issues that could prolong shedding.
Does postpartum hair loss happen with every pregnancy?
Not necessarily, and the experience can vary from one pregnancy to the next. Some women shed heavily after one baby and barely notice it after another. Having a second baby soon after the first can also shift the timing, since the hair cycle may not have fully reset.
Can I use minoxidil for postpartum hair loss?
Minoxidil is not recommended while breastfeeding, and it is usually unnecessary because postpartum shedding resolves on its own. If you are not breastfeeding, or once you have finished, and your hair has not recovered after about a year, talk to a doctor about whether minoxidil is appropriate.
The Bottom Line
Postpartum hair loss is temporary. Shedding usually starts two to four months after birth, peaks around month four, slows between six and twelve months, and most women are back to normal fullness by the baby's first birthday. Be gentle with your hair, avoid minoxidil and hair supplements while breastfeeding unless approved, and see a doctor if it lasts beyond a year.
