Why treating hair loss symptoms before a diagnosis is a waste of time
What causes hair loss in women in Nigeria, which medications are evidence-backed, and how to manage a long-term hair loss treatment plan.
Starting a hair loss medication before identifying the cause is the most common mistake, and the most expensive one. The treatment for iron deficiency anaemia is completely different from the treatment for PCOS-related hair loss. Getting the diagnosis right first saves months of ineffective treatment.
Hair loss in women: the causes matter more than the treatment
Hair loss (alopecia) in women has multiple causes, and the treatment depends entirely on which one is driving it.
Common causes in Nigerian women:
| Cause | Signs | First step |
|---|---|---|
| Iron deficiency anaemia | Fatigue, pale skin, brittle nails | Full blood count + serum ferritin |
| Thyroid dysfunction | Weight changes, fatigue, mood shifts | Thyroid function test (TSH, T3, T4) |
| Hormonal imbalance (PCOS) | Irregular periods, acne, weight gain | Hormonal panel |
| Traction alopecia | Hair loss at hairline/temples | Hairstyle change — no medication needed |
| Telogen effluvium | Diffuse shedding after stress/illness | Usually self-resolving in 3–6 months |
| Female pattern hair loss (FPHL) | Gradual thinning at crown | Long-term treatment required |
Iron deficiency anaemia is particularly relevant in Nigeria. A 2023 study found rates above 40% in some Nigerian women populations. Correcting iron deficiency often resolves or significantly reduces hair loss without any hair-specific medication.
Medication options with evidence
Minoxidil (topical): The only medication with strong clinical evidence for female pattern hair loss (FPHL). Applied directly to the scalp, 2% or 5% solution or foam. Available over the counter in Nigeria. Results take 3–6 months to appear and require continued use. Stopping reverses the effect.
Iron supplementation: Effective when iron deficiency is confirmed. Do not supplement without a blood test. Excess iron is harmful and causes its own symptoms.
Spironolactone: An anti-androgen used off-label for FPHL and PCOS-related hair loss. Requires a prescription. Not suitable during pregnancy. Requires reliable contraception.
Finasteride: Approved for male pattern baldness; used off-label in post-menopausal women in some cases. Not appropriate for women of reproductive age due to teratogenicity risk.
What doesn't work (but is widely sold in Nigeria)
- Biotin supplements: only effective with confirmed biotin deficiency, which is rare. No evidence for general hair growth.
- Hair growth oils and serums: no peer-reviewed clinical evidence for most products
- Herbal tonics: no peer-reviewed evidence for hair regrowth
The Nigerian supplement market is full of products marketed for hair growth without clinical backing. If a product doesn't cite a specific mechanism and evidence, treat it as cosmetic, not medical.
Managing a long-term hair loss treatment plan
Minoxidil and hormonal treatments require months of consistent use before results are visible. A care plan ensures you don't run out mid-treatment cycle. Famasi offers home delivery for women's health medications across Nigeria.
The most important thing to know: hair loss that has a treatable underlying cause responds well to treatment. Hair loss that doesn't have one (FPHL) responds to Minoxidil, but only while you keep using it.
