PCOS and Hair Loss: What Women Should Know

Noticing more hair in your brush lately, and you also have PCOS? You’re far from alone. Hair loss is one of the most common, and most upsetting, symptoms that comes with this condition. The good news is that it’s well understood, it’s treatable, and there are more options today than most people realize.

Before we get into it, one quick and important update: in May 2026, PCOS was officially renamed Polyendocrine Metabolic Ovarian Syndrome, or PMOS, by a global group of doctors and patient organizations [1]. The name changed because the condition affects a lot more than just the ovaries, but PCOS is still the name most people know, and both names will be used for the next few years. This guide uses PCOS since that’s what you’re likely searching for, but don’t be surprised if you start seeing PMOS in your doctor’s office soon.

Does PCOS Cause Hair Loss?

Yes. Hair loss affects a large number of women with PCOS, with studies estimating somewhere between 40% and 70% experience it at some point [2].

Here’s why it happens. PCOS causes your body to produce higher levels of hormones called androgens, sometimes called “male hormones,” even though everyone has some amount of them [3]. One of these, called DHT, is especially good at shrinking hair follicles over time. As the follicles shrink, each new hair that grows in gets a little thinner and finer, until eventually some follicles stop producing visible hair at all [3].

This type of hair loss has a real medical name: androgenic alopecia, sometimes also called female pattern hair loss.

What Does PCOS Hair Loss Actually Look Like?

This isn’t the same as losing hair in one round patch, which is a totally different condition. PCOS-related hair loss usually shows up as:

• A widening part line down the middle of your scalp
• Thinning that’s spread out, especially at the top and front of the head
• Hair that feels finer or won’t hold a style like it used to
• More strands than usual on your pillow, in the shower, or in your brush

This spread-out pattern is called diffuse thinning, and it’s different from the “one bald spot” pattern some other conditions cause. Knowing the difference matters, since it changes what kind of treatment actually makes sense.

What Causes the Hormone Imbalance in PCOS?

PCOS affects how your ovaries work and how your body manages hormones like insulin and androgens. Many women with PCOS also have higher insulin levels, and insulin can push the ovaries to produce even more androgens, which adds to hair thinning over time [3]. This is part of why doctors often look at the whole hormone picture, not just the hair, when managing PCOS.

How Is PCOS Hair Loss Diagnosed?

A doctor usually looks at a few things together, not just the hair itself:

1. Your overall pattern of hair thinning and where it’s happening
2. Blood tests to check hormone levels, including androgens
3. Other PCOS symptoms you may have, like irregular periods or acne
4. Ruling out other causes, like thyroid issues or low iron, which can also cause thinning and sometimes happen at the same time

Can PCOS Hair Loss Be Reversed?

In many cases, yes, especially if it’s caught and managed early. Since the hair loss is driven by hormones, treatment usually focuses on getting those hormones back into a healthier balance, alongside direct treatments for the scalp itself.

Common approaches include:

• Hormonal treatment, like certain birth control pills or medications such as spironolactone, which can lower androgen effects, prescribed and monitored by a doctor
• Minoxidil, a topical treatment that can help support regrowth in thinning areas
• Managing insulin resistance, sometimes through diet, exercise, or medication, since this can reduce the hormone imbalance driving the hair loss
• PRP (Platelet-Rich Plasma) therapy, which uses your own blood’s growth factors to support weaker hair follicles that are still active

None of these bring back a follicle that has completely stopped working, which is why earlier treatment tends to work better than waiting.

Is a Hair Transplant an Option for PCOS Hair Loss?

This is the part almost no one explains clearly, so here’s the honest answer.

A hair transplant works by moving healthy, permanent follicles from one area to a thinning one. This works best when there’s a clear “safe” donor area that isn’t affected by the hair loss, which is usually the case in typical male pattern baldness.

PCOS-related hair loss is trickier, because it’s often diffuse, meaning it can affect hair more broadly across the scalp, sometimes including areas that would normally be used as donor hair. Before recommending a transplant, a surgeon needs to check whether your donor area is genuinely stable and unaffected, and whether your hormone levels are under control. If the underlying hormone imbalance isn’t managed first, new hair loss can continue even after a transplant, which isn’t a good outcome for anyone.

This doesn’t mean a transplant is off the table. It means the right order of operations matters: get the hormonal side managed with your doctor first, let your hair loss pattern stabilize, and then a proper in-person evaluation can determine if surgical restoration makes sense, or if non-surgical support like PRP is the better fit for now. Our Hair Transplant for Women page covers what this evaluation process looks like in more detail.

How Is This Different From Other Causes of Female Hair Loss?

PCOS is just one of several hormone-related reasons women lose hair. Thyroid problems are another common one, and the two can sometimes overlap or get confused, since both affect hormones and both can cause thinning. If you want to understand how thyroid-related hair loss compares, our guide on hormonal hair loss and DHT explains how androgens work more broadly, beyond just PCOS.

When Should You See a Doctor About PCOS Hair Loss?

It’s worth getting checked if:

• You’re noticing steady thinning over several months, not just a bad hair day
• You have other PCOS symptoms, like irregular periods, acne, or extra facial hair
• Over-the-counter treatments haven’t made a difference after a few months
• The thinning is affecting your confidence or daily life, which is a completely valid reason on its own to seek help

A gynecologist or endocrinologist is usually the right starting point to manage the hormone side. Once things are stable, a hair restoration specialist can help you figure out the best path forward for your hair specifically.

A Note From Hair Restoration Seattle

Hormone-driven hair loss, including PCOS, calls for more than just a scalp check. At Hair Restoration Seattle, Dr. Javad Sajan looks at the full picture before recommending any treatment plan, surgical or not, since the right approach depends on how stable your hair loss pattern is and whether the underlying hormone imbalance is being managed. If you’re dealing with PCOS and noticing hair thinning, book a consultation with Dr. Sajan to talk through what’s realistic for your hair and your specific situation.

FAQs

Does PCOS cause permanent hair loss?

It can, if the hormone imbalance goes unmanaged for a long time, since follicles that fully stop producing hair don’t restart on their own. Earlier treatment gives the best chance of slowing or reversing thinning.

What percentage of women with PCOS experience hair loss?

Studies estimate that between 40% and 70% of women with PCOS experience some degree of hair thinning or loss.

Can losing weight help PCOS hair loss?

For some women, yes. Since insulin resistance can worsen the hormone imbalance behind PCOS hair loss, improvements in insulin sensitivity through weight management can help in some cases, though it isn’t a guaranteed fix on its own.

Is PCOS hair loss the same as normal shedding?

No. Everyone sheds some hair daily as part of a normal cycle. PCOS hair loss involves follicles shrinking over time due to hormones, leading to gradually thinner, finer hair rather than just temporary shedding.

Can you get a hair transplant if you have PCOS?

It’s possible in some cases, but only after hormone levels are managed and the hair loss pattern has stabilized. Since PCOS hair loss is often spread across the scalp, a careful evaluation of the donor area is needed before surgery makes sense.

Is PCOS now called something else?

Yes. In May 2026, PCOS was officially renamed Polyendocrine Metabolic Ovarian Syndrome (PMOS). Both names are being used during a transition period through 2028.
