“Losing 50–100 hairs a day is normal”
Shedding is part of the normal hair cycle, and you see more on wash days. Worry when your parting widens, your hairline or crown thins, or hair comes out in clumps for weeks. VERIFY

4 Not properly tested in people yetMyth
18 The evidence says noCauses
“Baldness comes from your mother's side”
One important gene sits on the X chromosome, which men get from their mother. But many other genes from both parents are involved.
“Stress can make your hair fall out”
A major shock or illness can push many hairs into the resting phase at once. Heavy shedding follows 2–3 months later and usually recovers.
“Hair fall after typhoid, dengue or COVID is permanent”
This is usually telogen effluvium: temporary shedding that settles within about six months as hair regrows.
“Heavy hair fall after delivery means you're going bald”
Shedding 2–4 months after birth is common and normally recovers within a year. Get iron and thyroid checked if it lasts longer.
“Breastfeeding causes hair loss after delivery”
The shedding comes from hormone levels falling after birth, whether or not you breastfeed.
“Only men get pattern baldness”
Many women get pattern thinning too. It shows as a widening parting rather than a receding hairline.
“Dandruff makes you go bald”
Dandruff doesn't cause baldness, but an inflamed, itchy scalp and scratching can increase shedding. Treating it helps.
“Hard water makes you go bald”
Hard water can leave hair dry and brittle so it breaks more. It doesn't cause hair loss from the root.
“High testosterone means you'll go bald”
How sensitive your follicles are to DHT matters far more than how much testosterone you have.
“Masturbation causes hair loss”
There is no evidence for this.
Habits
“Wearing caps or helmets makes you bald”
Headgear doesn't cause pattern baldness. Very tight headgear rubbing every day can break hairs; keep helmets clean and not too tight.
“Washing your hair every day causes hair fall”
The hairs you see in the drain were already shed. Washing just releases them, so wash days look worse.
“Shaving your head makes hair grow back thicker”
Shaving cuts hair at the surface and doesn't change the follicle. Regrowth only feels coarser because of the blunt tip.
“Tight hairstyles can cause hair loss”
Tight ponytails, braids and buns pulled daily can cause traction hair loss at the hairline, which can become permanent if it continues.
Medicines & procedures
“Minoxidil works for pattern hair loss”
Decades of trials show it slows loss and regrows some hair in many men and women, best at the crown and on recent thinning.
“Once you start minoxidil, stopping makes you balder than before”
If you stop, you gradually lose what it was holding and return to where you'd otherwise be. You don't end up worse.
“Shedding in the first weeks of minoxidil means it isn't working”
Early shedding in the first 2–8 weeks is common and usually settles. Judge results at 4–6 months.
“Finasteride works for men”
It lowers DHT and stops progression in most men, with some regrowth. It is a prescription medicine: talk to a doctor.
“Finasteride always ruins your sex life”
Sexual side effects affect a small minority and usually go away. Rare reports of persistent symptoms are why it should be a decision made with a doctor.
“A hair transplant is a one-time, permanent fix”
Transplanted hair usually lasts, but your own hair around it keeps thinning unless you also treat the hair loss with medicine.
“PRP regrows hair for everyone”
PRP has moderate evidence, especially alongside minoxidil, but results vary a lot between people and clinics.
“Microneedling boosts minoxidil”
Small trials suggest microneedling plus minoxidil works better than minoxidil alone. Done wrongly at home, it can damage the scalp.
Home remedies & products
“Hair oiling stops hair fall”
Oiling can make hair softer and less likely to break, but no oil has good evidence for stopping hair loss from the root.
“Rosemary oil works as well as minoxidil”
One small trial found it similar to 2% minoxidil, the weaker strength. It hasn't been convincingly repeated.
“Onion juice regrows hair”
The idea comes from one tiny study in patchy hair loss (alopecia areata). It hasn't been tested for everyday hair fall or baldness.
“Rice water makes hair grow”
There are no human studies of rice water for hair growth. It may make hair feel smoother; that isn't regrowth.
“Bhringraj oil regrows hair”
Mouse studies are promising, but there are no good-quality human trials yet.
“Natural or Ayurvedic means safe”
Some Ayurvedic preparations sold online have been found to contain lead, mercury or arsenic. Buy from makers that publish lab tests.
“Anti-hair-fall shampoos stop hair loss”
They are mostly cosmetic: a cleaner scalp and less breakage. They can't fix pattern hair loss or shedding from illness.
“Ketoconazole shampoo helps with hair loss”
It treats dandruff well, and small studies suggest a modest extra benefit for pattern hair loss alongside proven treatment.
“Serums with redensyl or procapil are clinically proven”
The studies are small, short and mostly run or paid for by the ingredient makers.
Diet & supplements
“Biotin gummies make hair grow”
Biotin only helps if you are deficient, which is rare. High doses can also distort blood tests, including thyroid tests.
“Low iron can cause hair fall”
Low ferritin is common, especially in women and vegetarians, and correcting a real deficiency can reduce shedding. Test first.
“Crash diets can make your hair fall out”
Losing weight fast or eating too little protein can trigger heavy shedding 2–3 months later. It recovers once eating returns to normal.
“Eating extra protein gives you more hair”
Enough protein supports normal growth; more than your body needs doesn't speed it up.
“Taking more supplements is safer than missing out”
Too much vitamin A or selenium, often from stacking supplements, is a known cause of hair loss. Test, then take only what you lack.
