Hair Fall in Women: Causes, Tests and Treatment in India

Most hair fall in women is one of two things: telogen effluvium, a temporary increase in shedding that starts two to three months after a trigger such as a high fever, childbirth or crash dieting, or female pattern hair loss, a slow thinning over the top of the scalp. Both are common, both are treatable, and in India they are frequently made worse by low iron, thyroid problems or PCOS, which is why finding the cause matters more than switching oils or shampoos.

This guide explains how to tell the types apart, what tests are useful, and what a dermatologist may suggest.

Is my hair fall normal or a problem?

Everyone sheds. Losing around 50 to 100 hairs a day is part of the normal hair cycle, and many women with long hair notice more because each strand is easier to see. If you oil and wash only twice a week, the hair that would have fallen over several days comes out at once in the shower.

It becomes worth investigating when:

• You see clumps on the pillow, comb or bathroom floor that are clearly more than usual.
• Your ponytail feels thinner, or your parting looks wider.
• You notice a smooth bald patch.
• The scalp is red, scaly, painful or itchy along with the hair fall.

What are the common causes of hair fall in women?

Telogen effluvium (shedding after a trigger)

Hair grows in cycles. A shock to the body can push many follicles into the resting (telogen) phase at once, and those hairs fall out together about two to three months later. That delay is why women often do not connect the shedding to its cause.

Common triggers we see in Indian women:

• Dengue, typhoid, malaria or COVID-19. Indian studies documented a wave of shedding after COVID infections, often starting within one to three months.
• Childbirth. Postpartum shedding typically peaks around three to four months after delivery.
• Crash dieting or a sudden drop in protein, including some fasting patterns and very low calorie diets.
• Major surgery, severe emotional stress or bereavement.
• Starting or stopping certain medicines, including some hormonal pills.

The hair comes out from the root, often with a small white bulb at the end. The good news is that telogen effluvium usually settles on its own once the trigger has passed, although regrowth to the old length takes many months.

Female pattern hair loss

This is gradual thinning, usually over the crown and along the central parting, while the front hairline stays mostly intact. It is influenced by genes and hormones. It can start in the twenties, but is more noticeable around menopause. Hairs become finer and shorter before they are lost, so women often describe their hair as limp or see more scalp under bright light.

Iron, thyroid and PCOS

These three deserve special mention in India:

• Iron deficiency is very common in Indian women because of periods, pregnancy and vegetarian diets low in absorbable iron. Low iron stores can contribute to shedding even before anaemia appears on a basic blood count.
• Thyroid disease, both underactive and overactive, can cause diffuse hair fall.
• PCOS raises androgen levels, which can thin scalp hair while increasing facial hair and acne. If you also have irregular periods or stubborn jawline acne, read our guide on hormonal acne and PCOS.

Other causes to rule out

• Alopecia areata, which causes round, smooth bald patches. See alopecia areata and patchy hair loss.
• Scalp conditions such as seborrheic dermatitis or fungal infection. See dandruff and seborrheic dermatitis.
• Traction alopecia from tight buns, braids or hair extensions worn for years.
• Breakage from heat styling, bleaching, keratin treatments and harsh straightening.

How do the different types of hair fall compare?

Type	What you notice	Typical timing	Usually reversible?
Telogen effluvium	Diffuse shedding, hair from the root	Starts 2 to 3 months after a trigger	Often, once the trigger is gone
Female pattern hair loss	Wider parting, thin crown, finer hairs	Slow, over years	Can be slowed and partly improved with treatment
Alopecia areata	Smooth round bald patches	Sudden	Often regrows, can recur
Traction alopecia	Thinning at the hairline and temples	Years of tight styling	Early on, yes. Late, may be permanent
Breakage	Short broken pieces, no root bulb	Linked to styling or chemicals	Yes, as new hair grows

Does hair oiling, hard water or shampoo cause hair fall?

These are the questions we hear most, and the honest answers are reassuring:

• Hair oiling is a lovely ritual and can reduce dryness and breakage, but it does not feed the follicle or stop shedding caused by illness, hormones or deficiency. On a flaky, itchy scalp, leaving oil on overnight can feed the yeast involved in dandruff.
• Hard water can make hair feel rough and tangle easily, which may increase breakage. It is not a recognised cause of hair falling from the root. A gentle conditioner after every wash helps more than worrying about the water.
• Shampoo does not cause hair fall. Hairs that come out while washing were already in the shedding phase. Washing more often simply spreads them out.
• Onion juice, rice water and home remedies have little reliable evidence, and some cause irritation or contact dermatitis.

What tests may a dermatologist suggest?

After examining your scalp, often with a handheld dermatoscope, your dermatologist may consider:

• Complete blood count
• Serum ferritin (iron stores)
• Thyroid function tests
• Vitamin B12 and vitamin D
• Hormone tests if there are signs of PCOS or other androgen excess

Not everyone needs every test. A good history, including recent fevers, deliveries, diets and medicines, often points to the answer.

How is hair fall in women treated?

Treatment depends on the cause, so it should follow a diagnosis.

For telogen effluvium: correcting the trigger is the main treatment. That might mean treating iron deficiency, adjusting a diet that is too low in protein, or simply waiting out the recovery after an illness with reassurance. Supplements help only if you are actually deficient. Taking random biotin or multivitamin capsules rarely helps, and biotin can interfere with some blood tests, including thyroid tests.

For female pattern hair loss: your dermatologist may consider:

• Topical minoxidil, which can slow thinning and improve density in many women with consistent use. An initial shedding phase in the first weeks is common and usually temporary.
• Low dose oral minoxidil in selected women, under medical supervision.
• Anti-androgen medicines in women with PCOS or high androgen levels, where suitable and with appropriate contraception advice.
• Platelet rich plasma (PRP) or microneedling as add-on options. Read more in our microneedling and PRP guide.

Results take patience. Most treatments need three to six months before any change is visible, and they work by continuing, not as a one-time course.

For scalp conditions, alopecia areata or traction: each has its own treatment, which is why a scalp examination matters.

What can I do at home right now?

• Eat regular meals with enough protein: dal, paneer, eggs, curd, fish or soy.
• Avoid crash diets.
• Loosen tight hairstyles and rotate how you tie your hair.
• Limit heat styling and chemical treatments while your hair recovers.
• Use a mild shampoo and conditioner, and comb gently from the ends upwards.
• Do not start steroid tablets, hormonal pills or high dose supplements without a prescription.

When to see a dermatologist

Book a dermatology review if:

• Shedding continues for more than six months.
• Your parting is widening or the crown is visibly thinner.
• You see bald patches, or hair loss in the eyebrows or eyelashes.
• The scalp is red, scaly, painful, oozing or scarred.
• Hair fall comes with irregular periods, acne, facial hair, fatigue, weight change or heavy menstrual bleeding.
