Does Laser Hair Removal Work for PCOS? A Comprehensive Analysis

Does Laser Hair Removal Work for PCOS

Does Laser Hair Removal Work for PCOS? PCOS, or Polycystic Ovary Syndrome, affects millions of women around the world. One of its most common and distressing symptoms is hirsutism, or excessive hair growth. Many women with PCOS turn to laser hair removal as a potential solution. But does it really work? This blog post delves into the science behind laser hair removal and PCOS, exploring its effectiveness, safety, and long-term results.

Understanding PCOS and Hirsutism

Polycystic Ovary Syndrome (PCOS) is a common endocrine disorder affecting 1 in 10 women of childbearing age1. It’s characterized by irregular menstrual cycles, high levels of androgens (male hormones), and polycystic ovaries. Hirsutism, a condition marked by excessive hair growth in areas where men typically have hair, is a common symptom of PCOS2.

Hirsutism can be particularly distressing, impacting self-esteem and quality of life. Traditional methods of hair removal like shaving, waxing, or plucking can be time-consuming and often yield temporary results. This has led many women with PCOS to consider laser hair removal.

How Laser Hair Removal Works

Laser hair removal uses concentrated light energy to damage hair follicles, inhibiting future hair growth3. The procedure targets the melanin in hair follicles, heating them to a point of irreversible damage. Over several sessions, this results in a significant reduction of hair growth.

The effectiveness of laser hair removal varies based on factors such as skin type, hair color, and the area treated. Darker hair tends to respond better to treatment because it contains more melanin, which absorbs the laser’s energy.

Laser Hair Removal and PCOS: The Evidence

Several studies have investigated the effectiveness of laser hair removal for women with PCOS. A 2013 study published in the Journal of Clinical and Aesthetic Dermatology found that after six sessions of laser hair removal, women with PCOS had a significant reduction in hirsutism4.

Another study published in the American Journal of Clinical Dermatology confirmed these results, finding that laser hair removal led to a substantial decrease in hair growth in women with PCOS5.

However, it’s essential to note that while laser hair removal can effectively reduce hair growth, it doesn’t address the underlying hormonal imbalance causing hirsutism in women with PCOS.

Long-Term Results and Considerations

While laser hair removal can significantly reduce hair growth, it’s not a permanent solution. Most people require maintenance treatments every six to twelve months to maintain results6. This is particularly true for women with PCOS, whose hormonal imbalance may continue to stimulate hair growth.

Additionally, laser hair removal can be expensive, with costs varying based on the area treated and the number of sessions required. Side effects, though generally mild, can include skin irritation and pigment changes7.


Laser hair removal can be an effective treatment for hirsutism in women with PCOS, reducing hair growth and improving quality of life. However, it doesn’t address the root cause of the condition – hormonal imbalance. Therefore, it’s crucial to combine it with other therapies aimed at managing PCOS. As always, consult with your healthcare provider before starting any new treatment.

Can laser hair removal cure PCOS?

No, laser hair removal can help manage the symptom of excessive hair growth (hirsutism) associated with PCOS but does not cure the syndrome itself.

How many laser hair removal sessions are needed for women with PCOS?

The number of sessions varies depending on the individual’s hair growth and hormonal levels. Typically, multiple sessions are required for optimal results.

Are there any side effects of laser hair removal?

Potential side effects can include skin irritation, pigment changes, and rare instances of blistering or scarring.

Can all hair colors be treated with laser hair removal?

Laser hair removal works best on darker hair. Blonde, red, gray, or white hair may not respond as effectively to treatment.
