Hair changes are a common experience during pregnancy and after delivery. While many women anticipate the often-touted "pregnancy glow" and thicker, more lustrous hair, some experience hair thinning and shedding. Understanding the science behind these changes, potential causes, and available solutions can help you navigate this journey with confidence.
Both men and women lose an average of around 50 to 100 hairs each day. This is a normal part of the hair growth cycle, which includes a growth phase (anagen), a resting phase (telogen), and a shedding phase (catagen).
Pregnancy brings about significant hormonal shifts that can profoundly impact hair growth.
During pregnancy, rising estrogen levels slow down the natural cycle of hair follicle shedding. Estrogen prolongs the anagen phase, causing hair to stay in the growth phase longer than usual. As a result, some women may actually lose fewer hairs while pregnant, leading to thicker, shinier hair. This is why many pregnant women experience a fuller ponytail and notice less hair in the drain.
However, not every woman experiences these positive changes. Every woman's body reacts differently to pregnancy hormones. Some women may find that their hair becomes:

Greasy or Limp: Higher hormone levels can increase oil production, making hair feel greasy.
Dry and Prone to Breakage: For others, hair may become dry and brittle.
Growing in Unexpected Places: Pregnancy hormones can also stimulate hair growth on the chin, belly, or back.
While less common than postpartum hair loss, hair loss during pregnancy can occur.
Some women may experience hair thinning and shedding due to stress or shock. The first trimester may stress the body as the balance of hormones shifts dramatically to support the growing baby. Stress may put more of the hairs on your head, 30 percent or more, into the telogen or “resting” phase of the hair life cycle. Instead of losing the average 100 hairs a day, you may lose 300 hairs a day. Hair loss due to hormonal shifts may not happen right away. Instead, it may take two to four months to notice thinning. This condition doesn’t generally last longer than six months and doesn’t result in permanent hair loss. This condition is called telogen effluvium, and it affects a small number of women during pregnancy.

Likewise, health issues may arise during pregnancy, leading to telogen effluvium. The shedding can be quite dramatic, especially if it’s related to an ongoing imbalance in hormones or essential vitamins.
Thyroid Problems: Thyroid disorders, like hyperthyroidism (too much thyroid hormone) or hypothyroidism (too little thyroid hormone), may be difficult to spot during pregnancy. Of the two conditions, hypothyroidism is more common, affecting some 2 or 3 out of 100 pregnant women. Hair loss is one symptom, along with muscle cramps, constipation, and exhaustion. Around 1 in 20 women may also experience thyroid issues (postpartum thyroiditis) after baby is born. In all cases, thyroid issues are typically diagnosed with a blood test.
Iron Deficiency: Iron deficiency happens when you don’t have enough red blood cells to get oxygen to different tissues in the body. It can cause hair thinning along with other symptoms, like fatigue, irregular heartbeat, exertional shortness of breath, and headache. Pregnant women are at a heightened risk of developing iron deficiency anemia, especially if their pregnancies are spaced close together, they’re pregnant with multiples, or they have severe morning sickness. This condition can also be diagnosed with a blood test.
While hair loss with these conditions isn’t permanent, your hair may not return to its normal thickness until hormone or vitamin levels have returned to normal ranges.
Many women see hair loss within a few months of delivery, generally peaking around four months postpartum. This is not true hair loss, but rather “excessive hair shedding” caused by a drop in the hormone estrogen. Again, this type of hair loss is considered telogen effluvium.

After giving birth, your estrogen levels drop suddenly, and all that hair that stayed in the growth phase now sheds at once. While it may be quite jarring to see 300 or more hairs shedding each day, it usually resolves on its own without treatment. Postpartum hair loss is a diffuse alopecia that begins about 2-4 months after delivery and lasts for about 6 months to 1 year. This results in women refraining from social interactions or using a hat or a wig to be involved socially.
A questionnaire-based cross-sectional study revealed that longer-term breastfeeding and preterm labor were independent predictors of postpartum hair loss. Breastfeeding delays the resumption of normal ovarian cycles by disrupting the pulsatile release of gonadotropin-releasing hormone from the hypothalamus and luteinizing hormone (LH) from the pituitary. Disruption of pulsatile LH signals results in reduced estradiol production. A previous study has concluded that hormone replacement therapy was not effective for postpartum hair loss.
It’s important to note that hair loss with telogen effluvium is typically uniform thinning. If you notice patches or more dramatic balding, there may be other issues at play. There are also genetic and autoimmune conditions that cause hair loss, whether you’re pregnant or not.
Androgenic Alopecia (Female Pattern Baldness): This condition is caused by a shortened growth phase of hair follicles and a lengthened time between shedding hair and new growth. Usually, androgenic alopecia is treated with medication designed to regrow hair.
Alopecia Areata: This autoimmune condition causes patchy hair loss on the scalp and other parts of the body. You may experience hair loss and regrowth that is unpredictable or cyclical. There is no cure for this type of hair loss, but certain treatments may help stop loss and regrow hair. Typically appearing as part of an autoimmune condition, this type of hair loss can be permanent, as your immune system attacks the hair follicles, mistaking them for unhealthy cells. With alopecia areata, hair often falls out in patches, usually on the scalp, although they can appear anywhere there is hair on the body.
It’s possible to be pregnant and have one of these conditions at the same time.
Your hair loss may have nothing to do with pregnancy or genetic conditions at all. If you’ve recently had your hair in tight hairstyles, had certain beauty treatments, or treated your hair roughly, you may have what’s called traction alopecia. Inflammation of hair follicles can lead to hair shedding and loss. Wearing your hair in tight ponytails or buns all the time can cause hair loss. Certain beauty treatments can also cause your hair to fall out. If hair is treated harshly, it can cause traction alopecia, which is hair loss caused by pulling on your hair excessively. Because traction alopecia can cause permanent hair loss, it’s important to recognize the signs and stop the practice before any lasting damage is done.
While hair changes during pregnancy and postpartum are often temporary, there are steps you can take to keep your hair healthy and strong.
Your growing baby needs nutrients, and so does your hair. Focus on foods rich in:
Iron: Spinach, red meat, lentils.
Protein: Eggs, chicken, nuts.
Omega-3 Fatty Acids: Salmon, chia seeds.
Biotin and Vitamins: Prenatal vitamins often provide these, supporting both you and your hair. Eating a whole foods diet consisting of plenty of fresh fruits and vegetables, healthy meats, and eggs, with limited processed and sugary foods, is a great first step. This kind of diet will give you more energy and keep anemia at bay.
Look for sulfate-free shampoos to avoid drying out your scalp.
Avoid excessive heat styling, pregnancy already changes your hair’s texture, and heat can cause breakage.
Use a wide-tooth comb to avoid tugging on your strands.
Stress impacts everything, including your hair. Maintaining a lifestyle that includes a daily dose of fun and relaxing activities can also help you manage stress. Gentle scalp massages, hydrating treatments, and time for yourself can do wonders for your well-being.
“Be gentle when brushing, and invest in a high-quality detangling brush to prevent breakage,” says Engelman. “Minimize the use of hot tools, as heat damage can lead to breakage and frizz.” If you color your hair, she suggests getting highlights, which require less chemical processing, instead of a full dye job.
Preventing hair loss may not always be possible, but there are certain behaviors that may make a difference. Two of the best methods include making healthy diet and lifestyle choices and watching for any potential underlying health conditions.
While most pregnancy-related hair changes are normal, it’s always best to check in with a specialist if:
Hair loss is sudden, patchy, or severe.
You’re noticing other symptoms, like fatigue, weight changes, or skin issues.
You suspect you have an underlying thyroid condition. If you suspect you have a iron deficiency, you should consult a doctor immediately.
Your hair can often tell a story about your overall health. Sometimes, conditions like thyroid imbalances or iron deficiency are at play, and these can be treated once identified.
If you’re pregnant and experiencing hair loss because of stress or hormones, or if you are in the postpartum phase, there may not be anything special you need to do. In these conditions, time is most often what’s needed. If you do feel there is an underlying condition, a professional can help you navigate the choices to find the best and safest treatment for you. Some treatments for hair loss, such as minoxidil, are not considered safe during pregnancy. On the other hand, medications such as levothyroxine, used to treat hypothyroidism, can be safely taken, as it has been categorized by the FDA as having no proven increase in the frequency of malformations or harmful effects on the fetus.
Normally, pregnant women do not have to change their daily hair care routine much, such as which shampoos and conditioners they use. However, this does not apply to dyeing the hair. To this day, this topic is hotly debated. Even today, there is no scientific evidence that hair dyeing during pregnancy has a harmful effect on the foetus. In general, however, doctors advise against it. However, if you do not want to give it up, you should at least use natural hair dyes during early pregnancy. This will help you prevent hair loss.
