Almost everyone worries about hair fall at some point, and almost everyone has received advice about it — from family, from friends, from social media. Some of that advice is harmless, some wastes money, and some delays finding the real cause. This article looks at ten of the most common hair fall myths, explains what is actually known, and helps you decide when hair loss is worth a visit to the doctor.
In short:
- Losing around 50–100 hairs a day is normal; hair is constantly shed and replaced.
- Most hair fall has an identifiable cause — genetics, a recent illness or childbirth, thyroid problems, low iron, or scalp conditions.
- No oil, juice or supplement regrows hair for everyone. Treatment depends on the cause.
- Sudden, patchy or heavy hair loss, or hair loss with other symptoms, should be checked by a doctor.
Myth 1: Washing your hair every day makes it fall out
Fact: The hairs you see in the bathroom drain after a wash had already detached from their follicles; washing simply rinses them out. If you wash less often, you notice more hair at once, which makes washing look like the culprit. How often you wash does not change how the follicles behave.
What can cause breakage is rough handling: very hot water, rubbing wet hair hard with a towel, or combing aggressively when hair is wet and fragile. Use lukewarm water, a mild shampoo, and pat hair dry.
Myth 2: Oiling makes new hair grow
Fact: Oiling is a valued tradition, and it does help the hair shaft — it softens hair, reduces friction and breakage, and coconut oil in particular may reduce protein loss from the shaft. But hair grows from the follicle beneath the skin, and there is no good evidence that applying oil revives follicles or reverses pattern baldness.
More oil is not better. On a scalp prone to dandruff (seborrhoeic dermatitis), heavy oil left on for long periods can make flaking and itching worse, because the yeast involved thrives on oils.
Myth 3: Cutting or shaving hair makes it grow back thicker
Fact: Trimming removes split ends, so hair looks healthier and fuller at the tips, but it does not affect the follicle, the growth rate or the number of hairs. The same applies to shaving a baby's head: hair that grows back after a mundan may look darker or coarser at first because the blunt tips are thicker than tapered natural ends, but the density is unchanged.
Myth 4: Baldness is inherited only from your mother's side
Fact: Pattern hair loss (androgenetic alopecia) is influenced by several genes inherited from both parents. One well-known gene sits on the X chromosome, which men inherit from their mothers — hence the myth — but a father's hair pattern matters too. Family history from either side increases the likelihood, though it does not decide exactly when or how much hair you will lose.
Myth 5: Wearing caps or helmets causes baldness
Fact: A cap or helmet does not cut off blood supply to follicles or cause pattern baldness. Riders should keep wearing helmets. Keep them clean and dry to avoid scalp irritation.
What does cause hair loss is constant pulling. Very tight ponytails, braids, buns or hair extensions worn for months can cause traction alopecia, usually along the hairline and temples. Caught early, it often recovers; long-standing traction can become permanent.
Myth 6: Hair fall after stress or illness is permanent
Fact: A major physical or emotional shock — a high fever such as dengue or typhoid, surgery, childbirth, crash dieting or severe stress — can push many hairs into the resting phase at once. This is called telogen effluvium. The shedding typically starts about two to three months after the trigger, which is why people rarely connect the two, and in most people it settles on its own within about six months.
If shedding continues beyond six months, or keeps recurring, see a doctor to look for an ongoing cause such as thyroid disease or iron deficiency. Stress management also helps; see our guide to stress management techniques.
Myth 7: Only men go bald
Fact: Women also experience pattern hair loss, but it usually looks different: a widening parting and overall thinning on top, rather than a receding hairline. Hair loss in women is also commonly linked to:
- Thyroid problems — see thyroid symptoms in women and hypothyroidism symptoms
- PCOS and other hormonal imbalances — see PCOS and hormonal imbalance in women
- Iron deficiency, which is common in Indian women with heavy periods or after pregnancy
- Shedding after childbirth, which usually peaks a few months after delivery and then recovers
Myth 8: Hair supplements fix hair fall for everyone
Fact: Supplements help when there is a deficiency to correct. If your iron, vitamin D or vitamin B12 is low, replacing it can help shedding settle. If your levels are normal, extra vitamins are unlikely to make a difference.
Biotin is heavily marketed for hair, but true biotin deficiency is rare. High-dose biotin can also interfere with some laboratory tests, including certain thyroid and heart tests, so tell your doctor and the laboratory if you take it. A simple blood test before buying supplements is usually the better first step.
Myth 9: Onion juice cures baldness
Fact: Onion juice is popular, and one small study suggested it might help some people with patchy hair loss (alopecia areata). There is no good evidence that it reverses pattern baldness. It can also irritate the scalp and cause a burning rash in sensitive skin. If you try it, test a small patch first, and do not let it delay seeing a doctor about sudden or patchy hair loss.
Myth 10: Once you start going bald, nothing can be done
Fact: Much depends on the cause. Shedding from illness, deficiency or thyroid problems often improves once the cause is treated. For pattern hair loss, doctor-prescribed treatments — such as topical minoxidil, and for some men oral finasteride — can slow further loss and regrow some hair in many people, although results vary and the benefit usually lasts only while treatment continues. These medicines have side effects and should be used under medical supervision.
For people with established pattern baldness who have enough healthy donor hair at the back and sides of the scalp, surgery is another option. A hair transplant moves follicles from these areas to thinning ones, and it should be planned only after a doctor has examined the scalp and confirmed the cause of hair loss. We explain what surgery can and cannot do in hair transplant myths and facts.
| Common belief | What is actually known |
|---|---|
| Daily washing causes hair fall | Washing rinses out hairs that were already shed |
| Oiling regrows hair | Oil protects the shaft; it does not revive follicles |
| Shaving makes hair thicker | Density and growth rate are unchanged |
| Baldness comes from the mother's side | Genes from both parents contribute |
| Stress hair fall is permanent | Usually settles within about six months |
| Supplements work for everyone | They help mainly when a deficiency exists |
When to See a Doctor About Hair Loss
Get your hair loss checked if:
- Hair falls out suddenly, in clumps, or leaves round bald patches
- The scalp is red, scaly, painful, itchy, or has pus or boils (in children, a fungal infection is a common cause)
- You also lose eyebrow, eyelash or body hair
- Hair loss comes with tiredness, weight change, feeling cold, irregular periods or acne
- Shedding has lasted more than six months
- A child is losing hair
A doctor will usually examine the scalp and may suggest blood tests such as a complete blood count, ferritin (iron stores), thyroid function (TSH), vitamin D and vitamin B12, and hormone tests for some women. Scalp conditions are best assessed by a dermatologist.
Getting Checked in Ambikapur
Sankalp Hospital does not have a dedicated dermatology department and does not perform hair transplant surgery. Our physicians can assess general health causes of hair loss, such as thyroid problems, anaemia and vitamin deficiencies, arrange the relevant blood tests, and advise when you should see a skin specialist. You can meet Dr. Shailesh Gupta (Internal Medicine), see our full team of doctors, or contact us to book a consultation.
