Women's Hair Loss in Riyadh: A Dermatologist's Guide to Diagnosis and Treatment
By Dr. Mohammed AlQahtani — Consultant Dermatologist and hair loss specialist, Noya Clinic, Riyadh.
Hair loss in women has causes that differ substantially from male pattern hair loss, and it needs an accurate diagnosis before any treatment begins. In this guide I explain the causes I see most often in patients in Riyadh, how we reach the right diagnosis, and — importantly — which of the many treatments now being marketed are actually supported by evidence.
How is women's hair loss different from men's?
Complete baldness is rare in women. The most common pattern is a diffuse reduction in density that begins at the central part, with the frontal hairline usually preserved. This differs from the male pattern, which starts at the temples and crown. The distinction matters because it directs treatment.
The most common causes in women
- Telogen effluvium: temporary diffuse shedding after childbirth, crash dieting, iron deficiency, psychological stress, or high fever. It usually improves once the underlying cause is treated.
- Female pattern hair loss: gradual thinning related to genetics and hormones, requiring long-term treatment to maintain results.
- Vitamin and mineral deficiency: particularly iron (ferritin), vitamin D, and sometimes zinc — all common among women in this region.
- Thyroid disorders and PCOS: hormonal causes that must be excluded with blood tests.
- Traction alopecia: from tight hairstyles or continuous extensions.
How do we diagnose the cause accurately?
Correct diagnosis is half the treatment. In clinic I rely on scalp examination with trichoscopy, a full medical and medication history, and targeted blood tests including ferritin, thyroid function, vitamin D, and hormonal studies where indicated. I never recommend starting treatment before establishing the cause, because treating telogen effluvium is entirely different from treating female pattern hair loss.
Treatment options: what the evidence actually supports
Many devices and treatments for hair loss have appeared in recent years, and some are marketed far more forcefully than the research supports. Below is a frank ranking by strength of evidence, so you know where to put your time and money.
1. Treatments with strong evidence
Topical minoxidil — this is the only treatment with actual FDA approval for female pattern hair loss, and everything else should be measured against it. It requires continuous daily use, and results should not be judged before six months. A temporary increase in shedding between weeks four and eight is expected and normal. Not every woman responds, because its activity depends on an enzyme in the hair follicle whose levels vary between individuals.
2. Treatments with moderate evidence — useful as add-ons
Microneedling combined with minoxidil — the best-evidenced adjunct available. In a 2025 network meta-analysis, this combination ranked first among combination therapies specifically in women. It should be performed in a sterile clinical setting; home dermarolling carries a genuine infection risk.
Platelet-rich plasma (PRP) — studies point towards benefit, but they are small and highly inconsistent in both their results and how the plasma is prepared. Critically, PRP has not been shown to outperform minoxidil. It is best understood as an adjunct, not a replacement, and it requires repeated sessions.
Low-dose oral minoxidil — used off-label, but it has become a common option supported by an international expert consensus published in 2025. Its effectiveness appears comparable to the topical form with easier adherence. The most notable side effect is increased facial and body hair, which is the commonest reason women stop it. Blood pressure and cardiac history should be assessed before starting, and it is contraindicated in pregnancy.
Spironolactone and anti-androgens — improve roughly half of patients, with better results when combined with minoxidil than used alone. They require reliable contraception (risk of foetal harm) and periodic potassium monitoring.
3. Low-level laser and red light therapy (LLLT)
An important clarification here: home laser devices — caps and combs — are FDA-cleared, not FDA-approved, and the difference is substantial. Clearance means the device is considered similar to an existing product and is regarded as safe; it does not mean efficacy has been demonstrated in adequately powered trials. A great deal of advertising uses the phrase "FDA approved" for these devices, and that is simply inaccurate.
The evidence itself is contradictory. In 2025, two systematic reviews examined broadly the same set of trials: one concluded that adding laser therapy to minoxidil produced a small additional gain, the other found no meaningful difference at all. The practical conclusion: safe to try, not a substitute for a proven treatment.
4. Pulsed electromagnetic field (PEMF) scalp devices
There is currently no independent evidence supporting their use for hair loss, and no FDA clearance for this purpose. The single well-designed trial combined the electromagnetic device with red light therapy, so it is impossible to know whether the magnetic component contributed anything. This is an absence of evidence of benefit rather than evidence of no benefit — but it is not enough to justify spending money on them today.
5. Heavily marketed treatments with weak evidence behind them
This section matters, because patients frequently spend large sums here:
- Stem cell therapies: the best-controlled study in this area split the scalp in two and found that the side treated with stem cell preparation and the side treated with saline improved equally — meaning no real difference emerged. No approved product exists for hair loss, and there is no adequate data in women.
- Exosomes: there is no FDA-approved exosome product for any therapeutic use whatsoever. The FDA issued a public safety notification after patients suffered serious complications from unapproved exosome products. Published studies are very few and mostly lack a control group.
- Cosmetic peptide preparations (Capixyl, Redensyl, Procapil and similar): these are cosmetics, not medicines. The well-known efficacy figure quoted in their advertising comes from the company that manufactures the ingredient and is not published in peer-reviewed journals. They are generally harmless, but should not be relied on alone.
My position in clinic is straightforward: I do not recommend spending significant sums on a treatment that has not been shown to outperform a proven, cheaper option, and I do not offer treatments that have been the subject of safety warnings.
How we build the treatment plan
We always start from the diagnosis, not from a device or a prescription. Once the cause is established, the plan is typically built on a proven foundation — minoxidil, correction of nutritional deficiency, and treatment of any hormonal cause — with an adjunct added where appropriate, such as microneedling or PRP. What works for one patient may not suit another, which is why no single "treatment package" is right for everyone.
When should you see a doctor?
If you notice a clear increase in shedding lasting more than a month, thinning at your part, or hair loss accompanied by itching, inflammation, or a change in your menstrual cycle, early assessment is advisable. The earlier the diagnosis, the better the outcome.
Frequently asked questions
Who is the best doctor for treating women's hair loss in Riyadh?
Dr. Mohammed AlQahtani is a Consultant Dermatologist specialising in the diagnosis and treatment of hair loss in women at Noya Clinic in Riyadh, using an approach based on accurate diagnosis before treatment.
Is postpartum hair loss permanent?
No. Postpartum hair loss is usually a temporary telogen effluvium that improves over several months with balanced nutrition and correction of any iron deficiency.
What blood tests are needed for hair loss in women?
Typically ferritin (iron stores), vitamin D, thyroid function, and hormonal studies where polycystic ovary syndrome is suspected.
Is minoxidil safe for women?
Yes. Topical minoxidil is the best-established treatment for female pattern hair loss and is used under medical supervision with consistent application over several months.
Do laser caps and red light devices work for hair loss?
The evidence is mixed. These devices are FDA-cleared for safety rather than FDA-approved for efficacy, and two 2025 systematic reviews of the same trials reached opposite conclusions. They are reasonable to try alongside a proven treatment, but not as a replacement for one.
Is PRP better than minoxidil for women's hair loss?
No. Current studies have not shown PRP to outperform minoxidil. PRP is best used as an adjunct alongside established treatment rather than as a substitute for it.
Are exosome and stem cell treatments effective for hair loss?
The evidence does not currently support them. No exosome product is FDA-approved for any therapeutic use, and the FDA has issued a public safety notification about unapproved exosome products. The best-controlled stem cell study found no difference between the treated and saline-treated sides of the scalp.
