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
1. Can zoey™ treat my hair loss?
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.
2. How long before I see results?
Minoxidil: 3–6 months for visible improvement. Spironolactone: 6–12 months. Iron supplementation: 3–6 months after correcting deficiency. Full assessment at 12 months.
3. Will my hair loss come back if I stop treatment?
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.
4. Is treatment safe during pregnancy?
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.
5. Does zoey™ deliver discreetly?
Yes. All zoey™ deliveries arrive in plain, unmarked packaging with no indication of contents.
