Hair Fall in Women: Finding the Real Cause and Treating It
Losing more hair than usual is common, treatable, and almost always has an identifiable cause. Our physicians test for it instead of guessing.
Some shedding is normal. Here's when it isn't.
Everyone sheds hair as part of a natural growth cycle. The question is how much, and how suddenly.
Normal daily shedding
Losing roughly 50–100 hairs a day is a normal part of the hair growth cycle and is not a cause for concern on its own.
Telogen effluvium
A sudden, diffuse increase in shedding, usually 2–3 months after a trigger such as childbirth, illness, surgery, crash dieting, or a major stressor.
Female pattern hair loss
Gradual thinning over the crown and a widening centre part, developing slowly over months to years rather than overnight.
Patchy hair loss
Distinct round or oval bald patches suggest a different process, such as alopecia areata, and are assessed separately from diffuse shedding.
What's actually behind it
In women, hair fall is rarely random. It usually traces back to one or more of these, and most are correctable once identified.
Iron deficiency
The single most common correctable cause of hair thinning in women, with or without anaemia. Low ferritin (iron stores) alone can trigger shedding.
Vitamin D deficiency
Very common in the Gulf despite abundant sunlight, largely due to indoor lifestyles and covering clothing. Linked to diffuse hair thinning.
Vitamin B12 deficiency
More common with restrictive diets, certain medications, or absorption issues. Affects the rapidly dividing cells of the hair follicle.
Zinc & protein deficiency
Crash dieting, restrictive eating, or low protein intake can push more follicles into the shedding phase than usual.
Thyroid dysfunction
Both an underactive and an overactive thyroid can cause diffuse hair thinning, and it is one of the first things we test for.
Hormonal changes
Postpartum shedding, PCOS, and perimenopause all shift hormone levels in ways that visibly affect the hair cycle.
Two women with the same amount of hair fall can have completely different causes, and completely different treatments. This is why a proper work-up, not a generic supplement, is the starting point.
The role of vitamins and minerals
Replacing what's actually low works. Taking supplements on top of normal levels usually doesn't, and can even interfere with your lab results.
Iron & ferritin
Restoring iron stores is often the single most effective step when ferritin is low, sometimes noticeable within a few months.
Vitamin D
Correcting a deficiency supports the hair growth cycle, alongside its broader role in bone and immune health.
Vitamin B12 & zinc
Both are cofactors the follicle needs for normal cell division. Replacement is guided by blood levels, not guesswork.
High-dose biotin supplements can distort certain blood tests, including thyroid and cardiac markers, leading to false results. Tell us if you're already taking a hair or nail supplement before any lab work. We may ask you to pause it for a few days first.
Biotin & dexpanthenol
The two most talked-about ingredients in hair supplements: what they actually do, and where they fit.
Biotin (vitamin B7)
A cofactor your body uses to build keratin, the structural protein of hair. Correcting a true biotin deficiency can meaningfully improve shedding, but biotin deficiency on its own is uncommon, and in women who are not deficient, extra biotin has limited proven benefit. It is most useful as part of a plan built on your actual test results, not taken alone as a fix-all.
Dexpanthenol (pro-vitamin B5)
Converts in the body to pantothenic acid, which supports the hair shaft and scalp condition and helps retain moisture. It's commonly combined with biotin in hair-support formulations and is generally well tolerated, used as a supporting measure alongside treatment of the underlying cause rather than a replacement for it.
How we diagnose the cause
No two cases of hair fall are treated the same way here, because no two causes are the same.
- A consultation covering your medical history, diet, medications, and hair-shedding pattern
- A scalp and hair examination to tell apart diffuse shedding, pattern thinning, and patchy loss
- Our Advanced Hair & Scalp Profile, a single panel covering iron studies, thyroid function, zinc, vitamins D and B12, and hormonal markers
- A follow-up to review results with you in plain language, and agree the treatment plan together
One panel built for hair-fall cases specifically: CBC, thyroid profile (TSH), zinc, iron, ferritin, vitamin B12, vitamin D, testosterone, and DHEAS. Covers the deficiencies and hormonal causes above in a single visit, and includes a complimentary follow-up consultation to walk through your results with you.
A plan tailored to your results
Once we know the cause, treatment follows it, not a one-size-fits-all supplement course.
Correcting a deficiency
If iron, vitamin D, B12, or another nutrient is low, we prescribe the right form and dose to bring it back to a normal range, then recheck it.
Managing an underlying condition
If thyroid function, PCOS, or another hormonal driver is involved, treatment addresses that condition directly, with hair regrowth following as a result.
Topical or supportive therapy
Where appropriate, your physician may add an evidence-based topical treatment such as minoxidil, alongside biotin or dexpanthenol as a supporting measure, never as a substitute for treating the cause.
Specialist referral when needed
Patchy hair loss, suspected autoimmune causes, or cases that don't respond as expected are referred on to dermatology for further assessment.
Frequently asked questions
Is hair fall after childbirth normal?
Yes. Postpartum shedding is a common form of telogen effluvium triggered by the drop in hormone levels after delivery. It usually settles within several months, but it's still worth a check if it's heavy or prolonged.
Can I just start taking biotin without seeing a doctor?
You can, but if your shedding is caused by iron, thyroid, or another deficiency that biotin doesn't address, you'll be spending money without treating the actual cause, and delaying real treatment.
Do I really need blood tests, or can you just tell by looking?
A scalp exam narrows down the pattern, but the underlying cause (iron, thyroid, vitamin levels, hormones) can only be confirmed with blood tests. That's what makes the treatment plan accurate rather than a guess.
How long before I see improvement?
Hair growth is slow by nature. Most patients start noticing less shedding within 8–12 weeks of correcting the underlying cause, with visible regrowth taking several months longer.
Is hair loss in women the same as male pattern baldness?
No. Female pattern hair loss usually shows as diffuse thinning over the crown with a widening part, rather than a receding hairline, and it has different underlying drivers and treatment options.
