Why PCOS Can Cause Hair Loss, And What You Can Do About It

Hair loss can be distressing, but many common hair loss conditions can be treated or managed successfully when diagnosed early. Understanding the cause of your hair loss is the first step towards restoring confidence.

Polycystic Ovary Syndrome (PCOS) affects around 1 in 10 women, and while it's often talked about in terms of irregular periods or acne, hair loss is one of its most distressing and under-discussed symptoms.

Is PCOS Affecting You?

If you’ve noticed your hair thinning, especially around your crown or parting, and you’re also living with PCOS, you’re not imagining it. Hormonal changes caused by PCOS can lead to gradual, often upsetting hair shedding. But here’s the good news: this type of hair loss is treatable.

How Does PCOS Cause Hair Thinning?

The main driver is a group of hormones called androgens, particularly testosterone and its more potent form, DHT. In women with PCOS, these hormones are often raised, and they can cause the hair follicles on your scalp to shrink, leading to thinner, weaker hairs and slower regrowth.

Other contributing factors include:

  • Insulin resistance
  • Chronic inflammation
  • Nutrient deficiencies
  • Hormonal changes (e.g. coming off the pill)

What PCOS Hair Loss Looks Like

Most women experience:

  • Thinning on the top of the scalp or along the parting
  • A reduction in volume or ponytail thickness
  • Increased shedding, especially when brushing or washing
  • No bald patches, but a wider parting or visible scalp
PCOS Hair Loss in Women

“Hair loss caused by PCOS can feel deeply personal and often isolating, but it’s also one of the most treatable types of hair loss we see. With the right diagnosis and a tailored plan, it’s absolutely possible to slow shedding and encourage regrowth.”

Gary Heron, Chief Trichologist

Associated PCOS Conditions:

  • Diffuse Thinning: PCOS can trigger gradual, all-over hair thinning — often mistaken for stress-related shedding or telogen effluvium.
  • Alopecia Areata: Hormonal imbalance and immune disruption in PCOS may increase your risk of autoimmune hair loss, including patchy shedding.

There Is Support, And There Are Solutions

At The Hair Loss Centre, we regularly support women with PCOS who feel overwhelmed by hair changes. Our trichologists understand how hormones, lifestyle, and scalp health work together, and how to treat PCOS-related hair loss in a way that’s supportive, realistic, and proven.

How We Diagnose and Treat Hair Loss for All Hair Types

Our approach starts with understanding your hair type, heritage, and care routine. We examine the scalp, review your history, and may recommend clinical testing. Treatments are always tailored to the individual and may include:

  • Topical or oral medication
  • Specialised scalp treatments
  • Lifestyle and hair care guidance
  • Ongoing monitoring and adjustments

Can Telogen Effluvium Return? Understanding Recurring Shedding and Stress

If you’ve been through Telogen Effluvium once, it’s very natural to wonder whether it might happen again. Many people feel particularly unsettled by the thought of recurring shedding, especially if regrowth has started and things finally seem to be improving. For some people, Telogen Effluvium does return. When it does, it’s rarely because the hair is damaged. It’s more often linked to how the body responds to ongoing pressure or repeated periods of stress. The follicles are still there and still capable of growing hair; they’re just reacting to what’s been going on.
