Hair fall in women: causes, tests and what helps

Short answer: Most hair fall in women comes from a few causes: heavy shedding a few months after a shock to the body (doctors call it telogen effluvium), female pattern hair loss, low iron, thyroid problems, hormone conditions such as PCOS, and tight hairstyles. When it started and what it looks like usually point to the cause. A simple blood test settles more cases than any shampoo.

This guide helps you match what you see to the likely cause, tells you which tests to ask for in Pakistan and roughly what they cost, and explains what a shampoo can and can't do.

How much hair fall is normal?

Losing 50 to 100 hairs a day is normal, according to the American Academy of Dermatology. The number you notice depends on how often you wash and comb, so wash days look worse: hairs that were already loose come out together (DermNet). If you are losing clearly more than that every day, or your parting or ponytail looks thinner, it is worth finding the cause.

Which cause fits you? A quick self-check

What you notice	Likely cause	Typical timing	First step
Hair comes out all over the head, in clumps on the pillow or in the shower	Telogen effluvium (shedding after a shock)	Starts about 3 months after an illness, fever, childbirth, surgery, crash diet or major stress	Think back 3 months. Usually settles on its own once the trigger has passed
Wider parting, thinner ponytail, more scalp showing on top	Female pattern hair loss	Slow, over months to years; more common after menopause	See a dermatologist; treatment works best early
Shedding plus tiredness or heavy periods	Low iron or anaemia	Gradual	Blood test: CBC and ferritin
Thinning, sometimes with hair coming out in clumps when you brush	Thyroid problem	Gradual	Blood test: TSH
Thinning plus acne, irregular periods, extra facial hair	PCOS or another hormone imbalance	Gradual	See a doctor or gynaecologist
Thinning along the hairline or where hair is pulled tight	Traction (tight buns, ponytails, braids)	Months to years	Loosen the style now; it can become permanent
Round, smooth bald patches	Possibly alopecia areata	Sudden	See a dermatologist

Sources for this table: AAD, 18 causes of hair loss, DermNet on shedding and DermNet on female pattern hair loss. It is a guide, not a diagnosis: two causes often happen together.

Shedding after dengue, typhoid or childbirth

Telogen effluvium is the classic "my hair started falling a few months after I was ill" story. A shock pushes many hairs into their resting phase at once, and they fall about three months later (DermNet). That delay is why few people connect the two.

In Pakistan this matters every autumn. In Punjab, dengue cases from 2012 to 2019 peaked in October (12,946 cases), followed by September (6,042) and November (5,592), according to a 2024 study of 25,682 patients. So a wave of shedding around January is common. The AAD notes that hair usually regrows once the trigger has passed.

Female pattern hair loss

This is the most common cause of hair loss in women, says the AAD. It shows up as a widening parting and thinner hair on top rather than a bald spot. Around 40% of women show some signs by age 50, according to DermNet. It runs in families.

The aim of treatment is to slow or stop the thinning; some women also regrow hair. A 2012 Cochrane review found minoxidil solution effective for female pattern hair loss (summarised by DermNet), and results need at least six months to judge. This is a medicine: start it with a dermatologist, especially if you are pregnant, planning a pregnancy or breastfeeding.

Low iron: common in Pakistan, but not always the answer

Anaemia is very common here. Pakistan's National Nutrition Survey 2018 found 41.7% of women of reproductive age were anaemic. A 2023 analysis of the same survey, covering 22,114 women, found 18.4% had iron deficiency anaemia.

The link between low iron and hair loss is less clear than many websites suggest. A 2006 review in the Journal of the American Academy of Dermatology found some studies linking low iron with hair loss in women and others that did not. Its authors still test iron in their own hair-loss patients, because iron deficiency should be treated anyway. Our advice: get tested before you take iron tablets. Too much iron is harmful too.

Thyroid, PCOS and other hormone causes

An underactive or overactive thyroid can thin the hair, and treating the thyroid can reverse it (AAD). PCOS can cause thinning too, usually alongside acne, irregular periods or extra facial hair. Most women with PCOS do not lose hair, though, so thinning alone does not mean you have it (DermNet). Stopping some birth control pills can also cause temporary shedding.

Which tests to ask for, and what they cost

Take this list to your doctor. They will choose what you need:

Test	Checks for	Rough price at a large Pakistani lab (Aug 2026)
CBC (complete blood count)	Anaemia	About Rs 700 to 900
Serum ferritin	Iron stores	About Rs 2,000 to 2,500
TSH	Thyroid	About Rs 1,700; a full thyroid profile is more

Prices are Chughtai Lab list prices published on Instacare (August 2026) and on public price lists from late 2025. They vary by city and lab, and discounts are common, so check with your lab first. Hormone tests for PCOS depend on your symptoms; your doctor will decide.

What a shampoo can and can't do

No shampoo fixes low iron, a thyroid problem or female pattern hair loss. A shampoo is on your scalp for a minute or two before you rinse it off. What it can do is keep your scalp clean and comfortable and avoid making breakage worse. If your scalp feels tight, dry or itchy after washing, a gentler sulphate-free shampoo is a reasonable switch.

You may have read that rosemary works as well as minoxidil. That comes from a 2015 trial in 100 men who used a rosemary oil lotion on the scalp twice a day for six months. Both groups gained a similar amount of hair. It was a small study, in men, with a leave-on lotion, so it doesn't prove that a rosemary shampoo regrows hair.

When to see a doctor

Round bald patches, or patches that are red, scaly, painful or itchy
Heavy shedding that lasts longer than six months
Hair loss with weight change, tiredness, irregular periods or new facial hair
Hair loss that started after a new medicine
A parting that keeps widening

Where GulStyles fits

Our Rosmara shampoo is sulphate-free, with rosemary extract and mint, made for thinning hair and dandruff-prone scalps. It is scalp care, not a treatment for the causes above. Use it 3 to 4 times a week, massage it in for a minute or two, and rinse well. If your hair fall has a medical cause, treat that first. A gentle shampoo is the everyday part of the routine, not the fix.

Common questions

Can stress cause hair fall?

Yes. Major stress is one of the triggers of telogen effluvium. The shedding usually starts about three months after the stressful event and settles once the stress has passed, though that can take several months.

Will my hair grow back after dengue or typhoid?

In most cases, yes. Shedding after a fever is usually telogen effluvium, and the hair regrows once the body has recovered. If shedding continues past six months, see a doctor to rule out a second cause such as low iron.

Does oiling stop hair fall?

Oiling does not treat the causes in this guide. A 2003 lab study found coconut oil reduced protein loss from hair, which may mean less breakage. The researchers worked for a coconut oil maker, and breakage is not the same as hair falling from the root.
