Here’s how to protect your hair while your body rebalances.
Pregnancy changes your hair, and not always in the way you expect. Some women get the thickest, shiniest hair of their lives while pregnant, then watch it fall out in fistfuls three months after delivery.
Others notice thinning and changed texture during pregnancy itself. Both patterns are hormone-driven, and both are usually temporary. But knowing that it’s temporary doesn’t make it less distressing when your ponytail is half its usual size, or your shower drain is clogging every day.
This guide explains the hormonal mechanics behind pregnancy-related hair changes, covers what’s normal vs. what warrants a doctor’s visit, and offers 7 specific strategies dermatologists recommend for managing hair loss during and after pregnancy.
And if you’re already dealing with visible thinning, our guide to thinning hair solutions and styling covers practical options for making hair look fuller while you wait for regrowth.
During pregnancy, elevated levels of estrogen and progesterone keep more hair follicles in the anagen (growth) phase for longer than usual. Normally, about 85–90% of your hair is growing at any given time, and the rest is in the telogen (resting) phase, preparing to shed.
Pregnancy hormones extend that growth window, so fewer strands fall out each day. The result: your hair feels thicker and looks fuller, sometimes noticeably so by the second trimester.
A recent study confirmed a statistically significant difference in anagen-to-telogen ratios between pregnant women at term and those at 4 months postpartum. During pregnancy, anagen rates are higher; postpartum, those ratios shift, sometimes dramatically.
Not everyone gets the pregnancy hair glow, though. Hormonal fluctuations can also make hair drier, change its texture (straighter hair may become wavy, or vice versa), or cause scalp sensitivity. These changes vary widely between individuals and even between pregnancies.
After delivery, estrogen levels drop rapidly. All those follicles that were held in the growth phase during pregnancy shift into telogen simultaneously and begin shedding about 2–4 months later. Dermatologists call this postpartum telogen effluvium, and it can feel dramatic. Instead of the normal 50–100 hairs per day, you might be losing 200–400+ strands daily.
Dr. Jennifer Sawaya, MD, FAAD, a board-certified dermatologist at U.S. Dermatology Partners, explains:
“During pregnancy, elevated estrogen levels keep hair in the anagen phase for longer periods, leading to thicker, fuller hair. After childbirth, estrogen levels drop drastically, pushing hair follicles into the telogen phase. This typically begins around three months postpartum, peaks between four to six months, and gradually improves by the one-year mark.”
If you’re breastfeeding, the timeline can shift. Dr. Brendan Camp, a board-certified dermatologist at MDCS Dermatology, notes that breastfeeding prolongs the drop in estrogen levels, which means postpartum shedding may appear closer to the 6-month mark rather than at 3–4 months.
The shedding is most noticeable around the hairline, temples, and crown — areas where hair is naturally finer. You might find clumps in your brush, on your pillow, or clogging the shower drain.
Alarming as it looks, the American Academy of Dermatology confirms that this excessive shedding is temporary and does not indicate permanent hair loss. Most women see their hair return to its pre-pregnancy fullness before or by their baby’s first birthday.
You can’t prevent postpartum shedding entirely. It’s a hormonal process your body needs to go through. But you can protect the hair you have, reduce unnecessary breakage, and support healthier regrowth. Here are 7 strategies backed by dermatologists, stylists, and research.
Pregnancy and breastfeeding place significant nutritional demands on your body, and your hair is one of the first things to show a shortfall. Iron, zinc, vitamin D, and B vitamins all play direct roles in the hair growth cycle. Low ferritin levels (the protein that stores iron) are one of the most common and under-recognized contributors to hair shedding in women.
A meta-analysis involving over 10,000 participants found that women with non-scarring alopecia had significantly lower ferritin levels compared to those without hair loss.
Continuing your prenatal vitamin after delivery, especially if you’re breastfeeding, helps cover baseline needs. But if shedding feels excessive, ask your OB-GYN or dermatologist for blood work to check ferritin, vitamin D, and thyroid function specifically. A confirmed deficiency is treatable, and correcting it can shorten the shedding window.
Our guide to hair loss and vitamin deficiencies goes deeper into which nutrients matter most and what levels to target.
Postpartum hair is structurally more vulnerable. The hormonal shifts affect the hair shaft itself, and new growth coming at different rates creates a mix of lengths and textures that tangle more easily. Aggressive brushing, heat styling, and tight hairstyles can turn normal shedding into unnecessary breakage.
Use a wide-tooth comb or a flexible-bristle detangling brush, and start from the ends, working upward. Avoid brushing when hair is soaking wet, that’s when strands are most elastic and most prone to snapping. If you’re going to use hot tools, keep the temperature below 180°C (360°F) and always apply a heat protectant first. Better yet, let your hair air-dry when you have the time (which, with a newborn, might be never, and that’s OK too).
Stylist tip: Sleep on a silk or satin pillowcase. Cotton creates friction that pulls on fragile postpartum hair overnight. A smooth pillowcase reduces tangles and breakage while you sleep, one less thing to worry about in the morning.
Tight ponytails, braids, buns, and cornrows put constant tension on the hair follicle. On a normal scalp, that tension can cause traction alopecia over time. On a postpartum scalp that’s already in a shedding cycle, it accelerates the problem.
A case series also documented how postpartum telogen effluvium can unmask underlying traction alopecia. Women who wore tight styles during pregnancy and postpartum showed patchy loss patterns that went beyond normal TE.
If you need your hair out of your face (and with a newborn, you probably do), use soft fabric scrunchies, claw clips, or loose braids instead of elastic bands. Position ponytails at different heights from day to day so the same follicles aren’t under constant strain.

Your scalp chemistry changes during and after pregnancy. Products that worked fine before might feel too heavy, too stripping, or leave more residue than usual. Switch to a gentle, sulfate-free shampoo and try to limit washing to every 2–3 days. Over-washing strips natural oils that fine and thinning hair needs for protection and shine.
For conditioner, apply from mid-length to ends only. Putting conditioner directly on your scalp weighs down roots and can clog follicles. A volumizing shampoo and conditioner help by coating each strand with lightweight polymers that add grip and body.
The AAD recommends volumizing products specifically for new moms dealing with postpartum thinning, and adds one more tip: avoid “intensive conditioners” or “conditioning shampoos” that deposit heavy silicones.
Stress has a measurable physiological effect on hair. Elevated cortisol levels push more follicles into the telogen phase prematurely, compounding the hormonal shedding that’s already happening. Sleep deprivation, anxiety, and the general demands of caring for a newborn all contribute.
Dr. Alan Bauman, a hair restoration physician, emphasizes that “nutrition, self-care, feeling calm, and getting rest are all part of the equation” when it comes to managing postpartum shedding.
What helps: short walks, breathing exercises, even 10 minutes of quiet time while the baby naps. Therapy or support groups are worth considering if anxiety is persistent.
Scalp massage has moved beyond folk remedy territory. A clinical study found that four minutes of daily scalp massage over 24 weeks produced measurable increases in hair thickness.
For postpartum women, massage has a double benefit: it increases blood flow to the scalp, and it’s a low-effort relaxation technique you can do while breastfeeding or watching TV. Use your fingertips (not nails) in small circular motions, working from the hairline toward the crown.
A silicone scalp massager provides more consistent pressure if your hands are tired. Do it for 4–5 minutes daily. Results take months, but the habit itself costs nothing and has real data behind it. Our roundup of scalp massagers for hair growth covers the best tools for this.
Postpartum telogen effluvium is common and self-resolving. But it’s not the only thing that can cause hair loss around pregnancy. Thyroid conditions (both hypo- and hyperthyroidism develop or worsen postpartum in about 5–10% of women), iron-deficiency anemia, and postpartum thyroiditis all produce shedding patterns that can look identical to normal TE but won’t resolve on their own.
See a dermatologist or your OB-GYN if: shedding hasn’t slowed down by 12 months postpartum, you notice patchy bald spots (rather than diffuse thinning), your part line is widening progressively, or the loss is accompanied by fatigue, weight changes, or scalp irritation.
Hair Color During Pregnancy: What You Should Know
Pregnancy can change how your hair responds to color, and stylists see it all the time. A formula that lifted perfectly before pregnancy may not get past a brassy yellow stage. Gray coverage that used to hold for weeks may wash out faster. Toner deposits differently. Your hair’s porosity and texture shift with your hormones, and that affects every chemical process.
As for safety, the American College of Obstetricians and Gynecologists (ACOG) states that hair dye is generally considered safe during pregnancy because the chemicals are not highly toxic and very little is absorbed through the scalp.
If you want to be extra cautious, some women wait until after the first trimester. Highlights and balayage are considered the lowest-risk options because the dye is applied to the hair shaft rather than directly on the scalp.
Our detailed guide to dyeing hair while pregnant or breastfeeding covers the full range of precautions and what to expect from color results during pregnancy.
Stylist tip: If your color isn’t taking the way it used to, don’t blame your stylist, and don’t ask them to leave the formula on longer. Pregnancy changes the hair’s internal structure and absorption patterns. Ask for a strand test before a full application, and consider switching to semi-permanent or demi-permanent color (less ammonia, gentler processing) until after delivery.
Here’s a general timeline of how hair changes through pregnancy and postpartum.
| Phase | What Typically Happens |
|---|---|
| First trimester | Hormones begin to rise. Hair may feel normal or slightly different in texture. Some women experience nausea-related nutritional gaps that affect hair later. |
| Second – third trimester | Estrogen peaks. Many women notice thicker, shinier hair as shedding slows. Others experience texture changes (wavy hair going straight, or vice versa). |
| 0–3 months postpartum | Estrogen drops. Follicles shift to telogen phase. Shedding hasn’t started visibly for most women. |
| 3–6 months postpartum | Peak shedding period. Noticeable thinning at temples, hairline, and crown. Shower drain and brush show significant hair loss. |
| 6–12 months postpartum | Shedding slows. New growth appears (short “baby hairs” at the hairline). Hair density gradually returns to baseline. |
| 12+ months postpartum | Most women are back to their pre-pregnancy hair. If shedding persists, see a dermatologist — something else may be going on. |
Below are the questions dermatologists and stylists hear most from pregnant and postpartum women about their hair.
Not entirely. Postpartum telogen effluvium is a hormonal process that happens as estrogen returns to pre-pregnancy levels, and no supplement, product, or routine can override that. What you can do is minimize additional shedding from breakage, correct nutritional deficiencies that aggravate it, and support your scalp health so regrowth comes in as strong as possible. Think damage control, not prevention.
Non-pregnant adults typically shed 50–100 hairs per day. During postpartum TE, that number can jump to 200–400+ daily. As alarming as it is, diffuse shedding across the whole scalp is within the normal postpartum range. What’s not normal: patchy bald spots, loss confined to one area, or shedding that persists beyond 12 months. Those patterns need a medical evaluation to rule out conditions like alopecia areata or thyroid dysfunction.
Breastfeeding doesn’t cause additional hair loss, but it can delay the timeline. Lactation keeps certain hormone levels lower for longer, which means the telogen shift may start later and the shedding peak may occur at 5–7 months rather than 3–4. The total amount of shedding is similar; it’s just spread over a longer window.
It depends on your comfort level, but there are practical benefits. Shorter hair has less weight pulling on roots, holds volume more easily, and creates the visual impression of more density. A layered bob or a collarbone-length lob are popular postpartum cuts because they look full without much styling effort. That said, if you love your long hair, you don’t have to cut it; focus on the other tips in this guide to reduce breakage and support regrowth.
See your OB-GYN or a dermatologist if shedding lasts beyond a year postpartum, if you notice round bald patches rather than general thinning, if your scalp is red or itchy, or if hair loss is accompanied by fatigue, weight changes, or feeling unusually cold (which could indicate a thyroid issue). Postpartum thyroiditis affects an estimated 5–10% of women and is frequently missed because its symptoms overlap with normal postpartum exhaustion. A simple blood panel can identify it. For a full breakdown of conditions that cause female hair loss, see our guide to hair loss causes in women.
Minoxidil is the only FDA-approved topical treatment for female pattern hair loss, but it is not recommended during pregnancy or breastfeeding. There is limited safety data on whether it passes into breast milk. If postpartum shedding is severe and you’re considering treatment, discuss options with your dermatologist. Some women start minoxidil after weaning.
Pregnancy and postpartum hair loss are among those things that nobody adequately prepares you for. It can feel isolating even though it affects the majority of new moms. The good news is that for most women, it’s temporary, it’s manageable, and your hair does come back.
Focus on the basics: good nutrition, gentle handling, scalp health, and stress management. If something feels off, get it checked. And while you’re waiting for regrowth, experiment with styles that make you feel good. Our free virtual try-on tool lets you preview cuts and colors without any commitment.
