Ahh — it’s a…hairball?! While pregnancy can be super exciting, some of the side effects — not so much. Just when you’re ready to throw in the towel, you’ll become a parent, and all the bad parts of pregnancy (yes, plural) will be forgotten.
Like morning sickness and constant peeing, hair loss may be a concern when you’re expecting. With all the increasingly uncomfortable symptoms, can’t you at least keep your mane?
We have good news: Hair loss during pregnancy is pretty rare. (But postpartum hair loss — that’s another story).
In this article, we’ll dive into what causes hair loss during pregnancy and offer tips for getting treatment if you experience hair loss while pregnant.
Hair loss during pregnancy is not common, TBH — at least, no more common than hair loss among women, in general.
In a 2014 study published in the Journal of Gynecology and Obstetrics, out of 400 pregnant women, 92 experienced hair loss at some point during pregnancy.
As a matter of fact, it’s more likely that pregnancy will make your hair fuller, not thinner. This is because the growth phase of the lifecycle of hair (known as the anagen phase) is longer for pregnant women, so you shed fewer hairs.
But there could be a few culprits responsible for hair loss during pregnancy. Let’s dive into some of the more common causes of hair loss.
Lots of rapid hormonal changes happen during pregnancy, which could cause telogen effluvium.
This type of hair loss happens about three months after a triggering event, like surgery or a major illness. It usually lasts for about six months, then stops on its own. If you’re shedding lots of white bulb hairs, it could be a sign of telogen effluvium.
Medical conditions like nutritional deficiencies and thyroid problems can lead to hair loss. Here’s what to know.
And when you’re pregnant, there can be some really odd cravings or intense nausea (especially in the first trimester) that may prevent you from eating a balanced diet. Iron deficiency is the leading deficiency globally, and iron deficiency anemia has been linked to hair loss.
A biotin deficiency is another potential contributor to thinning or brittle hair. Have your healthcare provider run a blood test to see if you’re meeting the necessary levels for all the essential nutrients, vitamins and minerals.
The American Academy of Dermatology recommends supplementing with other nutrients like zinc, vitamin C and vitamin E. But check with your healthcare provider before starting any new supplements, especially during pregnancy.
Human chorionic gonadotropin (hCG) and estrogen are two pregnancy-related hormones that can affect thyroid hormone levels. HCG can weakly stimulate the thyroid and estrogen can increase total thyroid hormone levels, though the “free”, or active, level stays the same. This can sometimes make it hard to diagnose a thyroid disorder, but it’s important to talk to your healthcare provider if you’re noticing hair loss.
It could be a symptom of a thyroid issue. In one study on people diagnosed with alopecia areata, abnormal thyroid hormone function was found in 24 percent of participants. It’s safe to assume a thyroid disease (like hypothyroidism) may affect your hair growth (or lack thereof).
Telogen effluvium hair loss typically occurs two to four months after treatment, but anagen effluvium can happen within days or weeks of usage. Discuss your symptoms and side effects with your healthcare provider, and never abruptly stop any medication without discussing it with your doctor first.
If you’re a fan of tight braids, buns or ponytails, your styling patterns may be what’s causing your thinning. These tight hairstyles can lead to a type of hair loss known as traction alopecia due to the constant pulling force and tension on the hair follicles.
Switching to looser styles might help reverse this type of hair loss.
It’s true: Stress can lead to hair fall-out, as it’s a trigger for telogen effluvium. Having a baby can be stressful, so it’s not far-fetched to think your new situation could lead to telogen effluvium hair loss.

When it comes to hair loss during pregnancy, the good news is it’s likely not permanent hair loss. You’ll probably experience regrowth, but it’s really dependent on the root cause.
Addressing the cause of hair loss can help you reverse it. By your baby’s first birthday, excessive hair shedding will be a distant memory.
For example, if you’ve been experiencing stress-related hair loss, practicing meditation may help you during stressful moments. Because who knew buying a baby stroller could be so confusing?

Your body undergoes lots of changes during pregnancy, but rest assured that most of the symptoms will eventually go away.
While hair loss is never a fun club to be a part of, there are some things you can do to help get your membership revoked. However, you’ll need to hold off on hair loss treatments until you’re postpartum (and, depending on the medication, until you’re no longer breastfeeding).
Here’s what might help in the meantime:
Eat healthy for two. While it’s tempting to load up on ice cream, try to maintain a healthy diet. Eat plenty of fruits and vegetables rich in flavonoids and antioxidants. These natural plant compounds help protect the hair follicle and encourage healthy hair growth. As noted, you want to avoid any nutritional deficiencies.
Take your vitamins. Supplementing with a hair vitamin might be a good bet, but speak with your dermatologist or healthcare provider to make sure it doesn’t overlap with your prenatal vitamin. See our guide for more tips on how to get thicker hair.
Give your strands a little TLC. Take it easy on hot tools, aggressive styling, harsh hair care and chemical treatments. Being gentle will help keep your hair healthy and strong.
Take a chill pill. Finding ways to lower stress is key, whether it’s yoga, exercise, a mid-day dance party or talking to a therapist. If life feels hard to manage, our online mental health services can help you get a better handle on things. One benefit of online therapy is that you don’t have to deal with any waiting rooms.

Pregnancy can be a beautiful (albeit complicated) experience. Here’s what to keep in mind:
Talk to your healthcare provider, as hair loss can often be a sign of bigger health issues like a nutritional deficiency or thyroid dysfunction. Don’t just ignore it — it’s definitely worth bringing up to your OB/GYN or healthcare provider.
If hair loss persists after pregnancy, there are science-backed hair loss treatments you can try to encourage new hair. Bookmark our guide to postpartum hair loss if you want to learn about hair loss after pregnancy.
Keep your stress under control. If parenting teaches new moms one thing, it’s that things don’t often go as planned. But learning ways to lower your stress can be helpful right now — and later too.
