Laser hair removal with PCOS — what works and what to expect

PCOS hirsutism is the single most common reason women book laser in our clinic. The good news: laser works. The caveat: PCOS keeps converting vellus hair into terminal hair in the background, so your plan is longer and the maintenance is lifetime.

Why PCOS plays by different rules

Elevated androgens convert fine hair into coarse hair on the face, neck, chest, and abdomen. Laser destroys currently-active follicles. It doesn't stop the hormonal drive creating new ones. Which is why medical treatment of PCOS itself matters as much as the laser sessions.

The PCOS-specific plan

• Blood work and endocrinology review first — confirm diagnosis, rule out thyroid and insulin issues
• 10–12 core sessions, not the usual 8
• Maintenance every 3–4 months, not every 12–18
• Spironolactone or a combined oral contraceptive if your endocrinologist prescribes
• Metformin + weight management where indicated — lowers androgens

What results to realistically expect

60–75% reduction after the core 10–12 sessions. Non-PCOS patients hit 70–90% on the same timeline. The difference is real but manageable with more frequent maintenance. Facial hair responds slowest; legs and body respond about the same as any other patient.

Combination therapy is where the real shift happens

If you're on spironolactone or a COC alongside laser, the result is dramatically better because you're addressing both the follicle and the hormonal signal creating new ones. Your dermatologist coordinates with your endocrinologist — that handoff matters.
