Short answer: yes, laser hair removal works on PCOS-related hair growth, and for most women it is the most effective long-term option available. But hormonal hair does not play by the same rules as ordinary hair, so it usually needs more sessions, more patience, and a bit of maintenance to keep it in check. You're not imagining it if your chin hair grew back faster than your friend's did after the same laser package. It's not a flaw in your skin or your willpower. It's androgens, doing what androgens do.

This guide walks through why PCOS causes excess hair growth in the first place, whether laser genuinely works on hormonally-driven hair, how many sessions you should realistically budget for, what it costs in the UK right now, and what else can support your results alongside the laser itself. If you want the bigger picture on facial hair specifically, we've also written a dedicated guide on getting facial hair from PCOS and what to do about it.

Why does PCOS cause excess hair growth?

Answer capsule: PCOS drives excess hair growth through higher circulating androgens and hair follicles that are more sensitive to those hormones.

Excess hair growth in a male pattern (on the chin, upper lip, jawline, chest, or lower abdomen) is called hirsutism, and it affects a large share of women with polycystic ovary syndrome. The root cause is hyperandrogenism, which is simply higher than typical levels of androgens (testosterone and its relatives) circulating in your body. PCOS is the most common cause of hirsutism in women of reproductive age, according to the NHS.

Here's the part that actually explains why this feels so unfair: it is not always about how much androgen you're producing. Some women with PCOS have androgen levels that look fairly normal on a blood test, but their hair follicles are simply more sensitive to those hormones. That sensitivity varies by ethnicity, family history, and even by the individual follicle, which is why you might have thick dark hairs on your chin and barely any extra hair anywhere else.

Your body is trying to tell you something when hair starts showing up somewhere new, growing coarser, or coming in darker. It is often one of the earliest visible clues that hormone levels have shifted, alongside irregular cycles, acne along the jawline, and stubborn weight changes. If you're not sure whether what you're seeing fits the pattern, our guide to the first signs of PCOS breaks down what tends to show up first and in what order.

Understanding the "why" matters because it changes what you should expect from treatment. Hirsutism caused by PCOS is a hormonal issue expressing itself through the hair follicle, not a hair problem on its own. That's the whole reason laser alone often is not quite enough, and why pairing it with support for the underlying hormone picture tends to get better long-term results than laser in isolation.

Does laser hair removal work on hormonal hair growth?

Answer capsule: Yes, laser genuinely reduces hormonal hair over time, though PCOS-related hair typically needs more sessions to respond fully.

Laser hair removal works by targeting melanin (pigment) in the hair shaft with a concentrated beam of light. The light heats the follicle enough to disable it, which slows or stops future growth from that follicle. It works best on dark, coarse hair set against lighter skin, because that combination gives the laser the clearest contrast to target. This is genuinely good news for a lot of PCOS-related hirsutism, since that hair is often dark and coarse by nature.

The catch is that laser only affects hairs that are actively growing at the time of treatment, and it cannot do anything about follicles that haven't been switched on yet. In PCOS, ongoing androgen stimulation keeps activating new follicles over months and years, which is why hormonal hair regrowth can outpace what a "standard" course of sessions would predict for someone without a hormonal driver. A 2024 systematic review of laser and light-based therapies for hirsutism in women with PCOS found that alexandrite laser produced meaningful improvements, that it tended to outperform intense pulsed light (IPL), and that combining laser with medical management (such as the contraceptive pill or metformin) outperformed laser used on its own. The review's authors also noted that the overall quality of evidence is still limited, so results vary more between individuals than glossy before-and-after photos suggest.

Translation: laser is not a magic fix for hormonal hair, and nobody selling it to you honestly should say it is. It's not a magic fix. But it gives your body what it's often missing in terms of consistent, cumulative follicle disruption that home hair removal simply cannot match.

Method	How it works	Typical sessions	Good for hormonal hair?
Laser (diode, alexandrite, Nd:YAG)	Targets melanin to disable the follicle	6 to 12, plus top-ups	Best long-term option, especially on dark coarse hair
Electrolysis	Electrical current destroys each root individually	Many, over months to years	Yes, and works on any hair or skin colour, but slow and time intensive
IPL (intense pulsed light)	Broader light spectrum, similar principle to laser	8 to 12 or more	Usually needs more sessions than laser for the same result
Eflornithine cream	Prescription cream that slows visible facial hair growth	Ongoing, daily use	Can slow regrowth between or alongside laser sessions
Shaving, waxing, plucking, depilatory cream	Removes visible hair above or at the surface	Repeated indefinitely	Manages appearance short term but does not reduce future growth

How many sessions will you actually need?

Answer capsule: Most people need 6 to 10 sessions to see visible results, but PCOS-driven hair often needs 8 to 12 sessions plus regular top-ups.

A "standard" course of laser hair removal in the UK is usually pitched at around 6 to 8 sessions, spaced 4 to 6 weeks apart on the face and slightly further apart on the body, because hair grows in cycles and the laser can only catch follicles that are in an active growth phase. For most people that's genuinely enough to see a dramatic, lasting reduction.

If your hair growth is being driven by PCOS, budget for more. It's common to need 8 to 12 sessions to get to a similar result, plus maintenance sessions every few months to a year afterwards, because ongoing androgen activity keeps recruiting new follicles into action. This is not a sign the laser "isn't working" on you. It is simply the underlying hormone picture doing its thing in the background while the laser does its job on the follicles it can reach.

A few things genuinely change your session count:

• Hair and skin contrast: dark, coarse hair on lighter skin responds fastest; finer, lighter, or red hair is harder for any laser to target
• Area treated: facial hair (chin, upper lip, jawline) tends to need more sessions than body hair because hormonal follicles there are especially persistent
• Consistency: skipping appointments or stretching gaps too far resets some of the progress, since new hairs need to be caught in their own growth cycle
• Whether the underlying hormone picture is being addressed at the same time, rather than left to keep activating fresh follicles unchecked

This is what I wish someone had told me before booking a laser package based on the price list alone: ask the clinic directly whether they have experience with PCOS-related hirsutism, and get an honest estimate of session numbers before you commit to a bundle. A reputable clinic will tell you upfront that hormonal hair is a different job.

What does laser hair removal cost in the UK?

Answer capsule: UK sessions typically run £30 to £300 per area, with full courses from around £180 up to £1,800 or more for larger areas.

Pricing varies a lot by clinic, region, and the size of the area being treated, and London clinics generally sit 30 to 50 percent above the national average. Here's a rough guide to what you might expect to pay per session and for a full course.

Area	Per session	Course (6 sessions)
Upper lip or chin	£30 to £80	£180 to £480
Upper lip and chin combined	£50 to £120	£300 to £720
Underarms	£40 to £90	£240 to £540
Lower legs	£80 to £180	£480 to £1,080
Full legs	£130 to £300	£780 to £1,800

Remember to factor in that PCOS-related hirsutism may need extra sessions beyond a standard course, and clinics often offer discounted top-up rates for existing clients rather than making you rebook a full price package. It's also worth knowing that laser hair removal is not usually available on the NHS and is generally considered a cosmetic treatment, so it will typically come out of your own pocket unless there's a specific clinical referral in place.

What else helps alongside laser?

Answer capsule: Pairing laser with a supportive skincare routine, calmer daily habits, and targeted nutrients can help your results go further.

Laser deals with the hair that's already there. It doesn't do anything about the hormone signalling that keeps recruiting new follicles, which is why so many women get frustrated with "why do I still have new hairs after eight sessions." Root cause, not symptom suppression is the whole philosophy behind pairing laser with broader hormone support, rather than treating hair removal as the entire plan.

A few things worth building into your routine alongside your laser course:

• Gentle, consistent skincare around treated areas, since laser can leave skin more sun-sensitive and reactive for a while. Our PCOS skincare tips guide covers what to prioritise if your skin is already dealing with hormonal acne or sensitivity.
• Daily SPF on any treated area, non-negotiably, since sun exposure between sessions increases the risk of pigmentation changes and can make the laser less effective at your next appointment.
• Patience with the timeline. Hormonal hair genuinely takes longer to respond, and comparing your progress to someone else's Instagram before-and-after (whose hair growth isn't hormonally driven) will only wind you up.
• Everyday nutritional support for the hair, skin and nails that are also affected by hormone fluctuations, whether that's the hair thinning on your scalp while the hair on your chin thickens (yes, PCOS can do both to the same person, which feels like a cruel joke), or skin that's more reactive than it used to be. If scalp thinning is your bigger worry right now, our guide on PCOS hair loss and what you can do about it covers that side of things in more depth.

This is also where a lot of women start looking at their daily nutrient intake, since biotin, zinc and other micronutrients contribute to the normal maintenance of hair, skin and nails, and myo-inositol is one of the most researched nutrients for supporting normal ovarian function in women with PCOS. Hormonal literacy isn't complicated, it's just rarely taught, which is a big part of why we built these products in the first place.

If it's the androgen side of things you want more support with, that's where Balance comes in. Myo-inositol contributes to normal ovarian function, and ashwagandha is traditionally used to support the body's response to everyday stress, which matters because stress hormones and androgens are closely linked in the PCOS picture. Balance is not a treatment for PCOS or hirsutism, and it will not stop hair growth on its own. It's a daily nutrient foundation for women who want to support their hormone balance alongside whatever else they're doing, laser included.

If you're pregnant, breastfeeding, taking medication, or managing a diagnosed condition, check with your GP or pharmacist before starting any new supplement, laser course, or hormone-related treatment plan.

Home laser devices vs in-clinic treatment: which wins?

Answer capsule: Clinic lasers are stronger and faster on hormonal hair, while home devices cost less upfront but demand far more sessions and patience.

Home IPL and laser devices have genuinely improved, and for finer, less stubborn hair they can deliver a reasonable reduction over many months of consistent use. But most home devices operate at a lower energy output than in-clinic machines, for safety reasons, which means they're working with less power against hair that's already harder to shift because it's hormonally driven.

For PCOS-related hirsutism specifically, in-clinic treatment tends to be the more efficient route, because:

• Clinic lasers can be adjusted by a trained practitioner for your specific hair and skin type, and stepped up in strength as needed
• A practitioner can spot skin reactions, irritation, or unexpected patterns early and adjust the plan
• Facial hair (the area most PCOS clients care about most) is delicate and close to the eyes, which makes professional handling worth the extra cost for many people
• Consistency is easier when you've paid for and booked a course, rather than relying on your own motivation on a Tuesday night

That said, a home device can be a sensible way to maintain results between clinic top-ups, or to manage smaller areas like the upper lip on a budget, once you understand your hair's particular stubbornness. Neither option is "cheating." Choose based on your budget, your skin sensitivity, how hormonally persistent your hair growth actually is, and honestly, how likely you are to stick with it.

Frequently asked questions

Does laser hair removal get rid of PCOS hair for good?

Laser produces a long-term reduction in hair growth, but "for good" isn't a fair promise for hormonally-driven hair. Because PCOS keeps activating new follicles, most people need ongoing maintenance sessions every few months to a year to keep results steady, rather than a one-off course that's done forever.

Is laser hair removal safe if you have PCOS?

Laser hair removal is generally considered safe for women with PCOS when carried out by a qualified practitioner. It doesn't interact with your hormones or medication. The main safety considerations are the same as for anyone: matching the laser type to your skin tone, patch testing, and protecting treated skin from sun exposure between sessions.

Why does PCOS hair grow back after laser?

Because androgen activity keeps switching on new follicles that weren't active during earlier sessions. It's not that the laser "failed" on the hairs it already worked on. It's that hormonal stimulation keeps recruiting fresh ones, which is why session counts and maintenance plans tend to run longer for hormonal hair than for hair with no hormonal driver.

Can you have laser hair removal on all skin tones?

Traditional lasers work best on lighter skin with dark hair, because they rely on contrast between hair pigment and skin pigment. Nd:YAG lasers are generally better suited to darker skin tones because they target hair colour more precisely while going easier on surrounding skin. Always ask a clinic what laser type they use and whether it's suitable for your specific skin tone before booking.

What's the best hair removal method for PCOS facial hair?

For most people with dark, coarse facial hair, laser is the most effective long-term option, with electrolysis as a strong alternative for finer or lighter hair that laser struggles to target. Eflornithine cream can slow visible regrowth between sessions. The "best" answer genuinely depends on your hair colour, skin tone, and how much time and budget you have.

Does the NHS cover laser hair removal for PCOS?

Generally, no. Laser hair removal is usually classed as a cosmetic treatment and isn't routinely available on the NHS, even when the underlying cause is PCOS. In rare cases involving significant psychological distress, a GP referral for funding may be considered locally, but this varies by area and isn't guaranteed.

Conclusion

Laser hair removal works, and it works particularly well on the dark, coarse hair that PCOS tends to produce. The honest caveat is that hormonal hair plays a longer game than average, so go in expecting more sessions, some ongoing maintenance, and a plan that sees laser as one part of the picture rather than the whole thing. Pair it with sun protection, a skincare routine that respects sensitised skin, and daily nutritional support for the hair, skin and hormone balance side of PCOS, and you give yourself the best shot at results that actually stick. Your diagnosis is a starting point, not a verdict, and that includes the hair on your chin.
