Why Is My Hair Falling?

1. Why is my hair falling so much suddenly?

The trigger probably happened 2–4 months ago, not now.

Stress, illness, high fever, crash dieting, pregnancy, or hormonal changes can push follicles into a resting phase. They all shed together months later. It feels sudden. It isn't.

The good news: this type of hair fall is usually temporary.

2. How many hairs fall in a day is normal?

Losing 50–100 hairs a day is completely normal.

You'll notice more on wash days,  hairs that were already ready to shed come out together. Don't count hairs in the drain. Instead, watch for:

• A widening parting

• A thinner ponytail

• More scalp showing at the crown

These are more meaningful signs than numbers.

3. Why is my hair thinning at the top?

This is usually genetic hair loss.

Follicles at the crown are sensitive to a hormone called DHT. Over time, DHT causes them to shrink and produce thinner, weaker hair. It happens gradually — which is why most people only notice it once thinning is already visible.

4. Can stress cause hair fall?

Yes.

Physical or emotional stress disrupts the hair growth cycle. The shedding usually shows up 2–3 months after the stressful period — not during it. In most cases, hair recovers once the stress settles.

5. Why is my hair falling after delivery?

During pregnancy, most hairs stay in the growth phase longer than usual.

After delivery, hormone levels shift and all those retained hairs shed together. It typically starts 2–4 months postpartum and improves on its own. Most women see full recovery within a year.

6. Why is my hair falling after COVID or fever?

A significant illness temporarily pushes follicles into a resting phase.

Shedding usually starts a few months after recovery and gradually improves. If it continues beyond 6 months, see a dermatologist.

7. Could a medical condition be causing my hair fall?

Yes — more often than people realise. The most common causes:

• Low ferritin (iron) — one of the most overlooked, especially in women

• Thyroid imbalance — both underactive and overactive affect the hair cycle

• Vitamin D deficiency — extremely common in India

• Vitamin B12 deficiency — especially in people who eat little or no animal protein

• PCOS — linked to hair thinning in women

8. Do I need blood tests for hair fall?

If your hair fall has been going on for more than 2–3 months, yes — it's worth investigating.

Ask your doctor for: CBC, Serum Ferritin, Vitamin D, Vitamin B12, Thyroid Profile (TSH, Free T3, Free T4)

For women, hormone testing may also be helpful.

9. Does oiling help with hair fall?

No.

Oiling makes hair softer and less prone to breakage — but it doesn't reach the follicle, which is where hair loss actually begins. If the cause is genetic, hormonal, or nutritional, oiling won't fix it.

10. Does washing hair cause hair fall?

No.

Wash as often as your scalp needs, usually 2–4 times a week. What matters is being gentle: no very hot water, no rough towel drying, no aggressive scrubbing.

11. Can shampoo alone prevent hair fall or help grow hair?

No shampoo can reverse hair loss or stimulate new growth.

A shampoo's job is to keep the scalp clean, balanced, and free of buildup — which creates a healthier environment for hair to grow. That matters, but it's maintenance, not treatment.

Think of shampoo as scalp hygiene. Not a solution.

12. Is blow drying bad for hair?

Blow drying doesn't cause hair loss, but excessive heat can weaken the hair shaft and increase breakage over time.

To minimise damage:

• Use a ionic or ceramic hair dryer — they distribute heat more evenly and reduce friction

• Always use a heat protectant before drying

• Keep the dryer at least 15 cm from your scalp

• Use medium heat, not maximum

• Don't direct heat at one spot for too long

A good dryer used correctly is far less damaging than most people think.

13. Does hair colouring cause hair fall?

Hair colour does not cause follicle-level hair loss.

But repeated chemical coloring—especially bleaching or overlapping applications — can damage the hair shaft, leading to breakage and dullness.

Safer choices:

• Ammonia-free colors—gentler on the hair structure

• Henna-based colors—a natural option, though results vary

If your scalp becomes inflamed or itchy after colouring, stop and see a dermatologist — it may be contact dermatitis, which can affect hair if left untreated.

14. What actually works for hair fall?

FDA-Approved Treatments

These are the most clinically validated options:

• Minoxidil (topical) — the most widely used treatment; works for both men and women; needs consistent, ongoing use to maintain results

• Oral Finasteride — approved for men; blocks DHT at the source; prescribed by a dermatologist

• PRP (Platelet-Rich Plasma) — a clinical procedure using growth factors from your own blood; done in a dermatology clinic; often combined with other treatments for better results

Oral Supplements for Hair

Supplements work — when you actually need them.

• Iron / Ferritin — if your levels are low, this is often the single biggest change you can make

• Vitamin D — deficiency is extremely common in India and directly linked to shedding

• Vitamin B12 — especially important if you're vegetarian or vegan

• Biotin — supports keratin production; useful if you're genuinely deficient

• Zinc — involved in the hair growth cycle; often missed in routine tests

Rule of thumb: test first, supplement based on results. Taking what you don't need rarely helps.

Hair Serums

For early thinning, a good daily serum is one of the most practical tools available — no prescription needed, no clinic visit, and it works while you sleep.

15. What should you look for in a good hair serum?

Not all serums are equal. Here's what actually matters:

Peptides — the most important ingredient class in modern hair science. Peptides signal follicles to stay in the growth phase longer. Look for a penta-peptide formulation — Ronagen is India's first penta-peptide hair serum, combining five targeted peptides in a single formula.

Proven molecules — the ingredient list should include names that have clinical evidence behind them:

• Redensyl — reactivates dormant follicle stem cells

• Procapil — targets DHT and improves scalp circulation

• AnaGain — derived from organic pea sprouts; shown to improve the ratio of growing to resting hairs

• Caffeine — stimulates follicles and counters DHT effects

• Rosemary extract — shown in studies to be comparable to Minoxidil for mild to moderate hair loss

• Biotin — supports the keratin structure of hair

Formulation quality — this is where most serums fall short. A good serum must be:

• Non-greasy — should absorb cleanly without residue

• No daily wash required — especially important for women; you shouldn't need to shampoo every day just because you used a serum

• Alcohol-free — alcohol dries the scalp and can worsen irritation over time

• Easy to apply — a serum you avoid using isn't working

And most importantly — it must work. Look for serums with visible results backed by real users, not just a strong ingredient list.

16. How long does hair fall treatment take to work?

At least 3–4 months before you can judge any treatment.

Hair biology is slow. Consistency matters far more than speed.

The bottom line

Hair fall is not one condition. It could be stress, genetics, a nutritional deficiency, or a hormonal issue — and the right solution depends on knowing which.

Understand the cause first. Start treatment early. And for persistent or significant hair fall, see a dermatologist before reaching for products.
