If you've been diagnosed with polycystic ovary syndrome — or suspect you have it — and noticed more hair turning up where you didn't expect it, you're far from alone. Unwanted hair growth is one of the most common and visible signs of PCOS, and it can affect your confidence long before you have a name for what's causing it. This guide explains what's actually happening, where hair tends to show up, and what you can realistically do about it.
Why PCOS Causes Extra Hair Growth
PCOS is a hormonal condition that affects how the ovaries work. One of its hallmarks is elevated androgens — hormones such as testosterone — which are present in everyone but are higher than typical in people with PCOS. The NHS notes that this androgen excess is responsible for most of the visible skin and hair changes associated with the condition.
When androgen levels rise, hair follicles in certain parts of the body respond by producing thicker, darker, coarser hair — what clinicians call terminal hair, the type that resembles male-pattern growth. The medical term for this is hirsutism, and it affects roughly 70% of people with PCOS, according to published reproductive endocrinology research.
Importantly, PCOS-related hair growth is not caused by anything you did. It is not a hygiene issue and it does not reflect poor grooming habits. It is a physiological response to hormone levels your body is producing.
Where Unwanted Hair Typically Appears
Androgens act on specific hair follicles that are sensitive to their effects. The areas most commonly affected in PCOS include:
- Face — upper lip, chin, and sideburns are the most reported sites
- Neck and jaw — often the first place people notice a change
- Chest and abdomen — a vertical line from navel downward is common
- Back and shoulders — tends to appear later or with higher androgen levels
- Inner thighs and bikini line — growth can extend further than typical
Not everyone experiences all of these areas. The pattern and density vary depending on individual androgen sensitivity and ethnicity — some people are more genetically predisposed to follicle sensitivity regardless of hormone levels.
What to Do First: Talk to a Doctor
Before building a removal routine, it is worth getting a clinical picture. A GP can run blood tests to check androgen levels and assess whether there is an underlying cause beyond PCOS — such as adrenal or thyroid involvement — that needs addressing separately.
The NHS outlines several medical treatment options for PCOS-related hirsutism:
- Combined oral contraceptive pill — the first-line option for most people; it suppresses androgen production and, over time, reduces the stimulus for new hair growth
- Eflornithine cream — a topical treatment applied to the face that slows hair regrowth; improvement is typically seen after 4–8 weeks of consistent use
- Spironolactone or other anti-androgens — sometimes prescribed in addition to or instead of the pill, depending on your history
- Laser hair removal — may be available on the NHS in some areas for people with PCOS-related facial hirsutism; worth asking your GP about eligibility
Medical treatment addresses the hormonal driver. Physical removal deals with existing hair in the meantime. For most people, the practical answer is both.
Day-to-Day Hair Removal: What Works and What to Watch For
Shaving
Shaving is the most accessible and, for many body areas, the most skin-friendly daily option. Contrary to the persistent myth, shaving does not make hair grow back thicker or faster — it simply cuts the hair at the surface, leaving a blunt tip that can feel coarser as it grows out. The hair itself is unchanged.
For PCOS skin, which can also be prone to acne and sensitivity due to the same androgen excess, technique matters:
- Always shave on wet skin with a quality shave gel or cream — dry shaving increases friction and the risk of irritation
- Use a sharp blade and replace it regularly; a dull blade drags and increases the chance of ingrown hairs
- Shave with the grain first, especially on sensitive areas, to reduce the risk of razor bumps
- Follow with a fragrance-free, non-comedogenic moisturiser to support the skin barrier
A well-weighted safety razor gives you a close, controlled shave with a single blade — which is gentler on skin prone to irritation than cartridge razors with multiple blades stacked close together. The Freya Starter Kit is designed specifically with sensitive skin in mind, and works well for facial hair, the bikini line, and body areas where PCOS-related growth tends to concentrate.

Waxing and Threading
Both remove hair from the root, so results last two to four weeks. They can work well for facial hair. The downside: they require hair to be a certain length before treatment, which means a growth window. For areas with active PCOS-related acne, waxing can exacerbate breakouts — check with a skin-aware therapist before booking.
Depilatory Creams
Chemical-based creams dissolve the hair shaft. They can irritate skin that is already sensitised by androgenic changes, particularly on the face. Always patch-test, and avoid on inflamed or broken skin.
Electrolysis and Laser
The only two methods considered permanent or long-term by clinical standards. Laser works best on darker hair against lighter skin, though newer technologies have expanded the range. Electrolysis is effective across all skin and hair types. Both require multiple sessions and a meaningful upfront investment, but can be transformative for people managing ongoing PCOS-related growth.
Managing the Emotional Side
It is worth naming this directly: hirsutism associated with PCOS carries a disproportionate emotional weight. Research consistently shows it affects self-esteem and quality of life more than many other PCOS symptoms. If you find yourself structuring your day around concealment, or feeling significant distress, that is worth raising with your GP or a counsellor alongside the physical management conversation. You are not being vain — you are managing a real symptom.
The Honest Bottom Line
PCOS-related hair growth is driven by hormones, not lifestyle choices, and it is not going to resolve overnight. The most effective approach combines medical treatment to address the hormonal cause with a consistent, low-irritation removal routine for existing hair. Start with your GP, find a removal method your skin tolerates well, and build from there — without the pressure to have it all figured out immediately.
Frequently Asked Questions
Does shaving make PCOS hair grow back thicker?
No. Shaving cuts hair at the surface but does not alter the follicle or the hair's growth rate or texture. Hair may feel coarser as the blunt tip grows out, but this is a tactile effect, not a structural change. The hormone levels driving PCOS hair growth are unaffected by how you remove existing hair.
Why does PCOS cause hair to grow on the face and chin?
PCOS raises androgen levels — hormones like testosterone — which act on follicles in androgen-sensitive areas including the chin, upper lip, and jawline. These follicles respond by producing thicker, darker terminal hair. The NHS identifies androgen excess as the primary driver of PCOS-related facial hair growth.
Will treating PCOS stop unwanted hair growth?
Medical treatment — such as the combined pill or anti-androgens — can reduce the hormonal stimulus for new hair growth over time, and many people see a gradual improvement in hair texture and density. However, terminal hairs that have already developed typically need to be managed with physical removal methods alongside any hormonal treatment.
What is the gentlest hair removal method for PCOS-prone skin?
Shaving on wet skin with a sharp, quality razor is widely considered the most skin-friendly daily option, particularly for people whose PCOS also causes acne or skin sensitivity. It avoids the trauma to the follicle that plucking or waxing can cause. Using a single-blade safety razor and a fragrance-free shave cream helps minimise irritation.
Can I get laser hair removal on the NHS for PCOS?
Potentially yes. The NHS notes that laser hair removal for facial hirsutism may be available in some areas for people with a confirmed PCOS diagnosis. Eligibility varies by region. Ask your GP to check what is available locally and whether a referral is possible, as it is worth exploring before paying privately.
