Hair loss in women is more common than most people realise — affecting up to 40% of women by age 50. Unlike male pattern hair loss (which follows a recognisable pattern), female hair loss can present differently, has more diverse causes, and requires a different treatment approach. This guide covers everything Singaporean women need to know.

Types of Women's Hair Loss {#types}

Women's hair loss presents differently from men's and encompasses several distinct conditions, each with different causes and treatment approaches.

Female Pattern Hair Loss (FPHL / Androgenetic Alopecia)

• The most common type in women
• Diffuse thinning across the top of the scalp (Ludwig pattern)
• Hairline is usually preserved (unlike men)
• Progressive if untreated
• Genetic and hormonal factors (similar to male AGA but with differences)

Telogen Effluvium (TE)

• Temporary, diffuse shedding triggered by a stressful event
• Common triggers: pregnancy/postpartum, significant weight loss, illness, surgery, medication changes, emotional stress
• Typically occurs 2–3 months after the trigger
• Self-resolving in most cases within 6–12 months once the trigger is addressed

Alopecia Areata

• Autoimmune condition causing patchy hair loss
• Round, smooth patches of hair loss
• Can affect any age
• May resolve spontaneously or require treatment (topical/injected steroids)
• Requires dermatologist assessment

Traction Alopecia

• Caused by chronic pulling on hair (tight ponytails, braids, extensions, hijab pins)
• Hair loss at the hairline and temples
• Preventable and potentially reversible if caught early
• Relevant for women who frequently wear tight hairstyles

Hormonal Hair Loss

• Related to hormonal changes: PCOS, menopause, thyroid dysfunction, postpartum
• Often presents as diffuse thinning
• Treating the underlying hormonal condition is primary

Causes {#causes}

Women's hair loss is multifactorial. Identifying the underlying cause is essential for effective treatment.

Hormonal

• Androgens — even normal female androgen levels can drive hair loss in genetically susceptible follicles
• PCOS — elevated androgens cause both scalp hair thinning and excess facial/body hair
• Menopause — declining oestrogen shifts the androgen:oestrogen ratio, worsening hair loss
• Thyroid dysfunction — both hypothyroidism and hyperthyroidism can cause hair loss
• Postpartum — oestrogen drop after delivery triggers telogen effluvium in many women

Nutritional

• Iron deficiency — the most common nutritional cause of hair loss in women (ferritin <40 mcg/L)
• Vitamin D deficiency — associated with hair loss in some studies
• Zinc deficiency — uncommon in Singapore but possible
• Protein deficiency — rare in well-nourished populations but can occur with restrictive diets
• Crash dieting — rapid weight loss triggers telogen effluvium

Medical

• Autoimmune conditions — alopecia areata, lupus
• Medication side effects — some oral contraceptives, antidepressants, blood thinners, chemotherapy
• Scalp conditions — seborrhoeic dermatitis, psoriasis, fungal infections
• Chronic illness — any significant illness can trigger temporary hair shedding

Lifestyle

• Stress — chronic stress contributes to telogen effluvium
• Heat and chemical damage — excessive straightening, colouring, perming
• Tight hairstyles — traction alopecia
• Poor sleep — may contribute to overall hair health

When to Seek Help {#when-to-seek-help}

Hair shedding of 50–100 hairs per day is normal. Consider seeking medical assessment if you experience any of the following:

• Noticeably increased shedding (more hair on pillow, in shower, on brush)
• Widening part line
• Visible scalp through hair (especially at the crown)
• Receding hairline
• Patchy hair loss
• Hair loss accompanied by other symptoms (fatigue, weight changes, menstrual irregularity)

The sooner you start treatment, the better the outcome — this is particularly true for FPHL, which is progressive.

Treatment Options {#treatments}

Treatment depends on the type and cause of hair loss. Here are the evidence-based options for women.

Minoxidil (Topical)

The first-line treatment for FPHL. Available in 2% and 5% concentrations.

• 2% solution/foam — approved for women; good starting point
• 5% solution/foam — higher efficacy but may cause more facial hair; used off-label in women
• Apply once or twice daily to affected scalp areas
• Results visible at 3–6 months; maximum effect at 12 months
• Must continue use to maintain benefits

Spironolactone (Oral)

An anti-androgen medication used off-label for FPHL and hormonal hair loss in women.

• Blocks androgen effects on hair follicles
• 50–200 mg daily
• Often combined with minoxidil for enhanced effect
• Must not be used during pregnancy (teratogenic to male foetuses)
• Requires reliable contraception during use

Iron Supplementation

If iron deficiency is identified (ferritin <40 mcg/L), supplementation can significantly improve hair loss.

• Iron bis-glycinate is generally better tolerated than ferrous sulphate
• Takes 3–6 months to see hair improvement after correcting iron levels
• Blood tests recommended before and during supplementation

Hormonal Treatment

• Oral contraceptive pills with anti-androgenic properties (Yasmin, Diane-35) for women with hormonal hair loss
• Thyroid medication if thyroid dysfunction is identified
• HRT may help menopausal hair loss in some women

What About Finasteride?

Finasteride is not approved for women and is contraindicated during pregnancy. Some dermatologists prescribe it off-label for post-menopausal women, but this should only be done under specialist supervision(Based on MOH guidelines and prescribing information).

Online Treatment Through zoey™ {#online}

zoey™ provides women's hair loss treatment through MOH-compliant telehealth.

How It Works

Lifestyle and Nutrition {#lifestyle}

Supporting hair health through lifestyle complements medical treatment.

Nutrition for Hair Health

• Iron-rich foods — red meat, spinach, lentils, fortified cereals
• Protein — adequate intake (1.0–1.2 g/kg/day) supports hair growth
• Vitamin D — consider supplementation if deficient (common in Singapore despite sun)
• Omega-3 fatty acids — fish, walnuts, flaxseed
• Biotin — deficiency is rare; supplementation is unlikely to help unless deficient

Hair Care Practices

• Minimise heat styling — use heat protectant when necessary
• Avoid tight hairstyles — especially if you notice thinning at the hairline
• Gentle hair handling — wide-tooth comb, minimal brushing when wet
• Mild shampoo — avoid harsh sulphates if scalp is sensitive
• Scalp massage — may improve blood flow; enjoyable if not proven(Based on MOH guidelines and prescribing information)

Stress Management

Chronic stress contributes to telogen effluvium. Evidence-based stress reduction (exercise, mindfulness, adequate sleep) supports overall hair health.

Myths Debunked {#myths}

"Washing hair too often causes hair loss"

False. Hair that falls out during washing was already in the shedding phase. Regular, gentle cleansing supports scalp health.

"Supplements can cure hair loss"

Supplements help only if a deficiency exists. For FPHL (the most common type), no supplement replaces minoxidil or anti-androgen therapy.

"Hair loss in women is always temporary"

Not always. FPHL is progressive and permanent without treatment. Telogen effluvium is temporary. Proper diagnosis is essential.

"Only older women lose hair"

FPHL can begin in the 20s–30s. Telogen effluvium and alopecia areata can affect women at any age.

FAQ {#faq}

1. What's the most common cause of hair loss in women?

Female pattern hair loss (FPHL) is the most common chronic cause. Telogen effluvium (temporary shedding after stress/illness) is the most common acute cause.

2. Will my hair grow back?

It depends on the type. Telogen effluvium is self-resolving. FPHL requires treatment to maintain and regrow hair. Alopecia areata may resolve spontaneously or need treatment.

3. Can I use men's hair loss treatments?

Minoxidil: yes (both 2% and 5% formulations). Finasteride: not recommended for women (particularly those of childbearing age). Spironolactone is a women-specific alternative.

4. Should I get blood tests?

Yes, if hair loss is new or unexplained. Tests for iron (ferritin), thyroid function, vitamin D, and hormones (testosterone, DHEA-S) help identify treatable causes.

5. How long before treatment works?

Minoxidil: visible results at 3–6 months, maximum effect at 12 months. Spironolactone: improvement typically at 6–12 months. Iron supplementation: 3–6 months after correcting levels.

6. Is postpartum hair loss permanent?

No. Postpartum telogen effluvium is temporary and self-resolving, typically within 6–12 months. If hair loss persists beyond 12 months, consider evaluation for FPHL.

7. Can stress alone cause hair loss?

Yes. Significant physical or emotional stress can trigger telogen effluvium. The shedding typically occurs 2–3 months after the stressful event and resolves once the stress is managed.

8. Does zoey™ treat all types of hair loss?

zoey™ treats FPHL, hormonal hair loss, and telogen effluvium through telehealth. Complex cases (alopecia areata, scarring alopecia, suspected autoimmune) may require in-person dermatologist referral.

9. Can hair loss treatments cause more shedding initially?

Yes. Minoxidil commonly causes temporary increased shedding in the first 2–4 weeks (the "dread shed"). This is a sign the treatment is working — new growth pushes out old hairs.

10. Are zoey™ hair treatments HSA-registered?

Yes. All medications prescribed through zoey™ are HSA-registered and dispensed through licensed pharmacy partners.
