Introduction
Spironolactone is a powerful anti-androgen medication increasingly used for women's hair loss. By blocking the effects of androgens on hair follicles, it can slow or stop hormonally-driven hair thinning. This guide covers dosing, side effects, contraception requirements, and what to expect.

What You Need to Know
Understanding the fundamentals of women's hair loss treatment helps you make informed decisions and set realistic expectations about your hair health journey.
The Evidence
Women's hair loss treatment has a solid evidence base, though less extensive than men's. Minoxidil has been studied in women for decades, and spironolactone has strong clinical support for anti-androgen therapy. Treatment is most effective when started early — before significant follicle loss has occurred.
Singapore Context
Singapore women face specific hair challenges including high humidity (affecting styling and product performance), air-conditioning-related dryness, and common nutritional factors (iron deficiency is prevalent among menstruating women, particularly those with heavy periods).
Practical Guidance
Here are the key practical considerations relevant to this topic for women in Singapore.
Treatment Approach
- Get diagnosed first — different types of hair loss require different treatments
- Blood tests if needed — ferritin, thyroid, vitamin D, hormones
- Be patient — hair grows slowly; most treatments take 3–12 months for visible results
- Consistency is key — irregular treatment use significantly reduces effectiveness
- Combine treatments when appropriate (e.g., minoxidil + spironolactone for FPHL)
What to Expect
- Initial shedding with minoxidil is normal and temporary (2–4 weeks)
- Slow, gradual improvement — compare photos monthly rather than looking in the mirror daily
- Maintenance required — most treatments need ongoing use to retain benefits
- Emotional support — hair loss can significantly affect self-esteem; consider talking to friends, partner, or a professional
Hair Care During Treatment
- Use gentle shampoo and minimal heat styling
- Avoid tight hairstyles that put traction on fragile hair
- Protect from sun — wear a hat in Singapore's strong UV
- Handle wet hair gently — use a wide-tooth comb; don't brush vigorously

FAQ
zoey™ treats female pattern hair loss, hormonal hair loss, and telogen effluvium through online consultations. Your doctor will assess whether your condition is suitable for telehealth management or requires specialist referral.
Minoxidil: 3–6 months for visible improvement. Spironolactone: 6–12 months. Iron supplementation: 3–6 months after correcting deficiency. Full assessment at 12 months.
For FPHL (pattern hair loss), yes — hair loss resumes if treatment is stopped. For telogen effluvium, once the trigger is resolved, hair regrows naturally. For iron deficiency, maintaining adequate iron levels prevents recurrence.
Minoxidil: not recommended during pregnancy (limited safety data). Spironolactone: contraindicated during pregnancy. If pregnant or planning pregnancy, discuss timing with your doctor. Iron supplementation is safe and often recommended.
