Quick answer. Female hair loss has many possible causes – female pattern hair loss (genetic thinning over the crown), telogen effluvium (stress, post-pregnancy, illness or crash dieting), iron deficiency, thyroid disease and PCOS – so the first step is a doctor’s diagnosis with blood tests rather than self-treating. First-line treatment is topical minoxidil plus correcting any underlying cause (iron, thyroid, PCOS); other options include PRP, low-level laser therapy, anti-androgens such as spironolactone for suitable women, and hair transplant for stable, selected candidates. In Singapore, topical minoxidil typically costs around S$40-100 a month, PRP roughly S$500-1,500 per session, and FUE hair transplant about S$8,000-15,000; finasteride is generally not first-line for women and is avoided in those who may become pregnant.
Hair loss in women is common but often misunderstood, and it behaves differently from male hair loss. Instead of a receding hairline, women usually notice diffuse thinning over the crown or a widening part, and the cause is frequently treatable or even reversible. Because the right treatment depends entirely on the cause, the most important step is seeing a doctor for an accurate diagnosis before spending money on products or procedures. This guide explains the common causes, how doctors investigate them, the treatments available in Singapore, and realistic costs.
At a glance
| Treatment / cause | What it targets | Typical cost |
|---|---|---|
| Topical minoxidil (2% / 5% / foam) | First-line for pattern thinning; prolongs growth phase | ~S$40-100 / month |
| Oral low-dose minoxidil | Pattern loss where topical is unsuitable (prescription, supervised) | Prescription + consultation fees |
| Spironolactone (anti-androgen) | Androgen-driven loss in suitable women; not in pregnancy | Prescription + consultation fees |
| Treating underlying cause (iron / thyroid / PCOS) | Reversible shedding from deficiency or hormonal disorder | Cost of tests + relevant treatment |
| PRP injections | Stimulating follicles; usually a course + maintenance | ~S$500-1,500 / session |
| Low-level laser therapy (LLLT) | Non-invasive adjunct to other treatments | ~S$100-500 / session |
| FUE hair transplant | Stable female pattern loss in selected candidates | ~S$8,000-15,000 total |
Common causes of hair loss in women
Women’s hair loss has several distinct causes, and more than one can occur at the same time:
- Female pattern hair loss (androgenetic alopecia): the most common cause, producing gradual, diffuse thinning over the crown and a widening part while the frontal hairline is usually preserved. It is genetic and hormonally influenced and tends to progress slowly without treatment.
- Telogen effluvium: a temporary, diffuse shedding triggered by a stressor a few months earlier – childbirth, high fever or illness, surgery, severe stress, crash dieting or stopping the contraceptive pill. It is often reversible once the trigger resolves.
- Iron deficiency / anaemia: low iron stores (ferritin) are common in menstruating women and can contribute to shedding.
- Thyroid disorders: both an underactive and overactive thyroid can cause diffuse thinning, usually alongside other symptoms such as fatigue or weight change.
- PCOS (polycystic ovary syndrome): androgen excess can drive pattern thinning, sometimes at a younger age, often with acne or irregular periods.
- Traction alopecia: from tight hairstyles, buns, braids or extensions pulling on the hairline over time.
- Alopecia areata: an autoimmune condition causing well-defined patchy bald spots rather than diffuse thinning.
Why seeing a doctor for diagnosis comes first
Because pattern hair loss, telogen effluvium, iron deficiency, thyroid problems and PCOS can all look like “thinning hair,” treating the wrong cause wastes time and money. A doctor (such as a dermatologist or your GP) will take a history, examine your scalp – sometimes with dermoscopy – and order blood tests. These commonly include a full blood count, iron studies and ferritin, thyroid function, and, where androgen excess or PCOS is suspected, hormone levels. Identifying and correcting an underlying cause (for example, replacing iron or treating a thyroid disorder) is often the single most effective step, and may be enough on its own for shedding to recover.
Treatment options for female hair loss in Singapore
Treatment is matched to the cause, and several approaches are often combined:
- Topical minoxidil (first-line): available as a 2% or 5% solution, or a 5% foam. The 5% strength and foam are convenient and effective, but the stronger preparation is more likely to cause scalp irritation and occasional unwanted facial hair, so the choice should be guided by your doctor. It works best when started early and must be continued to maintain results.
- Oral low-dose minoxidil: increasingly used off-label under medical supervision for women who cannot tolerate or comply with the topical form. It is prescription-only and requires monitoring for side effects.
- Treating underlying causes: iron replacement, thyroid treatment, or managing PCOS where these are contributing.
- Anti-androgens (spironolactone): prescribed off-label for suitable women, especially where androgens play a role. It must not be used in pregnancy or by women planning pregnancy because of birth-defect risk.
- PRP (platelet-rich plasma): injections of your own plasma to stimulate follicles, usually given as a course and then maintenance.
- Low-level laser therapy (LLLT): non-invasive red-light devices used in clinic or at home as an adjunct.
- Hair transplant: an option for selected women with stable female pattern loss and a good donor area, after medical treatment has been optimised.
A note on finasteride: it is generally not first-line for women and is used only cautiously in carefully selected cases. It is avoided in women who may become pregnant because it can cause serious birth defects.
Typical costs in Singapore
Prices vary by clinic, product and the number of sessions needed; the figures below are typical market ranges, not quotes. Topical minoxidil generally runs around S$40-100 a month. PRP is commonly around S$500-1,500 per session, and a course is usually needed. Low-level laser therapy sessions are often in the region of S$100-500 each. FUE hair transplant typically costs about S$8,000-15,000 overall (roughly S$4-7 per graft, with most cases needing several thousand grafts). Prescription medicines such as oral minoxidil or spironolactone are charged on top of the consultation. Always confirm pricing and what each package includes directly with the clinic.
Realistic expectations
Hair regrowth is slow – most treatments need 4-6 months of consistent use before a visible difference, and benefits are maintained only as long as treatment continues. Starting early, while follicles are still active, gives the best results; long-standing, advanced thinning responds less well. Telogen effluvium often recovers on its own once the trigger is addressed, whereas female pattern hair loss is usually a long-term condition managed rather than cured. Setting realistic goals with your doctor and reviewing progress with photos helps you judge what is genuinely working.
