In short: female pattern hair loss (FPHL) is the most common cause of long-term thinning in women. Follicles on the top of the head gradually shrink, so the parting widens and the scalp shows more. The front hairline usually stays. It's often genetic and can start any time after puberty, becoming more common around menopause. Minoxidil is the proven first treatment. Anti-androgens such as spironolactone are added for some women.
What it looks like
- A widening centre parting, sometimes in a "Christmas tree" shape, wider at the front
- Thinning on the top and crown; a smaller ponytail
- More fine, short hairs among normal ones
- The front hairline is usually kept (unlike men's pattern)
Stages (the Ludwig scale)
| Stage | What you see |
|---|---|
| I (mild) | Parting slightly wider; thinning noticeable mainly when hair is parted |
| II (moderate) | Clearly wider parting; scalp visible on top |
| III (extensive) | Marked thinning across the top; scalp easily visible |
Some dermatologists use the Sinclair scale (1–5) instead, which compares the width of the parting. The earlier treatment starts, the more hair can be kept.
What causes it
- Genetics: often runs in families, on either side.
- Androgens: follicles on the top of the head may be sensitive to androgen hormones, even when blood levels are normal. In some women, high androgens (for example from PCOS) are part of the picture.
- Age and menopause: falling oestrogen can make thinning more noticeable.
- Other causes often coexist: low iron, thyroid problems or a recent shedding episode. → 9 causes of hair loss in women
FPHL or telogen effluvium?
| Female pattern hair loss | Telogen effluvium | |
|---|---|---|
| What you notice | Thinning, wider parting | Lots of hairs falling |
| Where | Top and crown, parting | All over |
| Start | Gradual, over years | Sudden, 2–4 months after a trigger |
| Hairs | Many fine, short hairs | Full-length hairs with white bulbs |
| Course | Slowly progressive without treatment | Usually settles within 6 months |
They can happen together. A shedding episode often makes underlying FPHL noticeable for the first time.
Treatments
| Treatment | Evidence | Notes |
|---|---|---|
| Minoxidil 2% twice daily or 5% foam once daily | Strong | First-line; judge at 6–12 months |
| Low-dose oral minoxidil | Moderate, growing | If topical doesn't suit; prescription |
| Spironolactone | Moderate | Especially with high androgens or PCOS; contraception needed |
| Contraceptive pill with anti-androgen effect | Moderate | Via a gynaecologist; not for everyone |
| Low-level laser devices (caps, combs) | Moderate | Cost and consistency matter |
| PRP | Moderate, variable | Clinic protocols differ |
| Finasteride / dutasteride | Limited | Specialist only; never during pregnancy or if it's possible |
| Correcting low iron or vitamin D | Helps if deficient | Test first |
| Ayurvedic oils and supplements | Limited | Fine for comfort; don't replace proven treatment |
Camouflage while you wait: changing your parting, volumising cuts, hair fibres or tinted scalp powders, and toppers.
Realistic expectations
- The main goal is to stop progression. Regrowth is a bonus, and more likely with early treatment.
- Results take 6–12 months.
- Treatment usually needs to continue to keep results.
- Monthly photos of your parting help you judge progress. → How to track results
See a doctor soon if you have: round bald patches that appear suddenly · hair coming out in clumps · redness, pain, pus, scaling or scarring on the scalp · hair loss with fever, weight loss, irregular periods, acne or new facial hair · eyebrow or eyelash loss · hair loss in a child.
