Treating PCOS-related facial hair requires a combination approach: slowing new hair growth with hormonal medication while removing existing hair through physical methods. Neither strategy works well alone, and most treatments take at least six months to show meaningful results. The good news is that several effective options exist, from prescription medications to professional hair removal, and many women see significant improvement once they find the right combination.
Facial hair in PCOS is driven by androgens, particularly testosterone. Your skin converts testosterone into a more potent form that acts directly on hair follicles, stimulating thicker, darker hair growth in areas like the upper lip, chin, and jawline. Treating the hair itself without addressing the hormonal signal behind it leads to a frustrating cycle of removal and regrowth.
Why PCOS Facial Hair Keeps Growing Back
The root cause is elevated androgen levels. Testosterone circulates in your blood and reaches the skin, where enzymes in hair follicles and oil glands convert it into its biologically active form, dihydrotestosterone (DHT). DHT is far more potent than testosterone itself at stimulating hair growth, which is why even modestly elevated testosterone levels can cause noticeable facial hair. This process happens locally in the skin, meaning your blood test results don’t always reflect what’s happening at the follicle level.
Because the hormonal signal is ongoing, any treatment that only targets the hair (shaving, waxing, threading) provides temporary relief. The follicle receives a continuous “grow” signal from androgens, so the hair returns. Effective long-term treatment interrupts that signal, removes the follicle’s ability to respond, or both.
First-Line Treatment: Birth Control Pills
Combined oral contraceptive pills are the recommended starting treatment for PCOS-related facial hair, according to the 2023 international evidence-based guidelines for PCOS management. They work through two mechanisms: the estrogen component increases a protein in your blood that binds testosterone and takes it out of circulation, while certain progestins directly block androgen activity at the skin.
Not all birth control pills are equally helpful. Pills containing anti-androgenic progestins like drospirenone (a derivative of spironolactone) or cyproterone acetate are preferred because they actively counteract testosterone’s effects. Third-generation progestins such as desogestrel and norgestimate are also good options since they have low androgenic activity. Older formulations containing levonorgestrel are less ideal because that progestin has more androgenic properties, which can work against you.
The tradeoff with more anti-androgenic pills is a slightly higher risk of blood clots compared to older formulations. Your prescriber will weigh this against your individual risk factors.
Adding an Anti-Androgen Medication
If six months on birth control hasn’t produced enough improvement, guidelines recommend adding an anti-androgen medication. Spironolactone is the most commonly prescribed option in the United States. It blocks androgen receptors in the skin and reduces testosterone production.
In clinical studies, spironolactone produced a clear beneficial effect on facial hair in 19 out of 20 women with moderate to severe hirsutism. Changes in hair diameter, density, and growth rate became noticeable within two months. The maximum effect appeared at six months and held steady through 12 months of continued use. It worked equally well whether the hirsutism was caused by PCOS or had no identifiable hormonal cause.
Spironolactone must be paired with reliable contraception because it can cause birth defects. This is one reason doctors often prescribe it alongside birth control pills rather than on its own. If you stop taking it, the hair gradually returns as androgen levels rise again, so most women stay on it long-term.
Topical Prescription Cream
Eflornithine cream is a prescription topical that slows facial hair growth by blocking an enzyme hair follicles need to produce new hair. It’s applied twice daily to affected areas, with at least eight hours between applications. It doesn’t remove hair or change existing hair, so you still need a removal method alongside it.
Results take time. You may notice some improvement within four weeks, but the full benefit typically becomes apparent within six months. The practical sign it’s working is that you spend less time on your usual hair removal routine because regrowth slows down. If you stop using it, hair growth returns to its previous rate within about eight weeks.
Eflornithine is particularly useful for women who can’t take hormonal medications or who want additional help in a specific area like the upper lip or chin.
Professional Hair Removal Methods
While medications reduce new hair growth, professional hair removal targets the follicles that are already active. The two main options are laser hair removal and electrolysis.
Laser Hair Removal
Laser works by targeting the pigment in dark hair, heating the follicle enough to damage it. It’s faster per session than electrolysis and covers larger areas efficiently. However, there’s an important consideration specific to PCOS: laser treatment on hormonally sensitive facial areas has been reported to cause paradoxical hair growth in some women with the condition. This means the laser can actually stimulate new hair in the treated area or nearby, the opposite of the intended effect. This risk is worth discussing with your provider before starting treatment.
Laser is most effective on dark hair against lighter skin tones. It typically reduces hair density but rarely eliminates it entirely, especially when ongoing hormonal stimulation is present.
Electrolysis
Electrolysis destroys individual follicles using an electric current delivered through a tiny probe. It works on all hair colors and skin types, which gives it an advantage over laser. Research comparing the two methods in PCOS patients found that electrolysis showed superior efficacy for permanent hair removal in hormonally sensitive facial areas. Although it requires more sessions (since each follicle is treated individually), it ultimately offered a more reliable and permanent solution.
The downside is time. Treating a full chin or upper lip area requires multiple sessions over months or even years, depending on the extent of hair growth. Sessions can be uncomfortable, though the pain is brief for each follicle.
Supplements That May Help
Two supplements have some clinical evidence behind them for PCOS facial hair, though neither replaces medical treatment.
Spearmint tea has been studied specifically in women with hirsutism. Drinking spearmint tea twice daily for 30 days reduced free testosterone by about 24% and total testosterone by about 29% in women with PCOS. An earlier, shorter study found a 30% drop in free testosterone after just five days. These are meaningful hormonal shifts, though the studies were small and it’s unclear how much visible hair reduction follows from these numbers alone. Two cups a day is the amount used in the research.
Myo-inositol, taken at 2 grams twice daily for six months, led to decreased hirsutism severity scores in women with mild to moderate facial hair growth. It also lowered total androgen levels, LH, and LDL cholesterol. The effect on hair was modest compared to prescription anti-androgens, but inositol has a very mild side effect profile and may provide additional metabolic benefits for PCOS.
Building an Effective Treatment Plan
The most effective approach layers treatments together. A typical combination looks like this: a birth control pill with an anti-androgenic progestin as the foundation, spironolactone added if needed after six months, eflornithine cream for targeted facial areas, and electrolysis or laser for permanent follicle removal.
Patience is essential. Hair follicles cycle through growth and rest phases lasting several months, so even when hormonal treatment is working perfectly, it takes time for the full effect to show. The clinical guideline specifically calls for waiting a minimum of six months before judging whether a medication is working. Starting professional hair removal at the same time as medication makes sense because you’re attacking the problem from both directions: medication slows new growth while electrolysis or laser removes existing follicles.
Clinicians assess facial hair severity using a standardized scoring system that rates hair growth across body regions on a 0 to 4 scale. A total score of 8 or above is considered hirsutism, with 8 to 16 classified as mild, 17 to 24 as moderate, and above 24 as severe. Knowing where you fall on this scale helps set realistic expectations. Mild hirsutism often responds well to birth control alone, while moderate to severe cases typically need combination therapy.
Everyday removal methods like shaving, threading, and waxing remain part of the routine for most women while waiting for medical treatments to take effect. Shaving does not make hair grow back thicker despite the persistent belief. It simply cuts the hair at the surface, creating a blunt tip that can feel coarser as it grows out.
