Hair Fall Home Remedies: Onion (Pyaz) Juice, Oiling and When to Test
The drain cover fills up, the comb is full, and someone at home says “onion (pyaz) juice”. Before you start grating, it helps to know why hair is falling, because hair fall home remedies can support a healthy scalp, but they can’t fix low iron, a thyroid problem or the shedding that follows a fever. Here’s an honest guide to both halves.
In brief
- Common triggers: fever or illness, childbirth, crash dieting, stress, low iron, thyroid problems
- Delay: shedding often starts about 2 to 3 months after the trigger
- Onion juice: some people like it; it can irritate, and smell lingers
- Oiling: good for dry lengths and breakage; not a regrowth treatment
- Tests worth asking about: blood count, ferritin (iron stores), thyroid (TSH), sometimes vitamin D and B12

Shedding, breakage or thinning?
These three look alike in a comb but mean different things.
- Shedding: full-length hairs, often with a tiny white bulb at the root. Everyone sheds daily; a sudden increase is what you notice.
- Breakage: short, snapped pieces without a bulb. Caused by rough handling, tight buns, heat tools, bleaching, dryness. This one responds well to oiling and gentler care.
- Thinning: a widening parting, visible scalp at the crown, or a receding hairline. Often hereditary or hormonal, and worth a doctor’s opinion early.
Collect the hairs from one wash on a white tissue and look. That tells you more than a week of worrying.
When hair fall needs blood tests
Put this section before the remedies because it’s the one that changes outcomes. See a doctor, and ask about tests, if: We also sorted home remedies for baldness into what helps and what doesn’t.
- Hair is coming out in handfuls, or for more than about 3 months
- You also feel tired, breathless on stairs, cold, have heavy periods or pale skin (low iron is very common)
- You notice weight change, constipation, dry skin, feeling cold or a racing heart (thyroid problems can cause either)
- Periods have become irregular, with acne or facial hair (possible PCOS)
- You have round bald patches, broken hairs with scaling, or a sore, itchy, red scalp (these need direct treatment)
- Hair fall began after a new medicine
- It’s a child losing hair
Commonly requested tests include a complete blood count, serum ferritin, thyroid function (TSH), and sometimes vitamin D, B12 and hormone tests. Your doctor decides which ones fit. Please don’t start iron or biotin tablets on your own. Too much iron is harmful, and biotin supplements can interfere with some blood test results, including thyroid tests, so mention them before any blood draw.
You’re pregnant or breastfeeding: shedding a few months after delivery is common and usually settles, but ask your doctor before any supplement or scalp product with active ingredients. You have diabetes or take blood thinners: tell your doctor about hair loss, as some conditions and medicines are linked to it, and don’t change doses on your own. Onion juice, garlic and strong essential oils can cause scalp burns or allergic rashes; avoid them on broken, sore or infected skin and never use them on babies.
Hair fall home remedies: onion juice, honestly
Onion juice is the most talked-about hair fall home remedy in desi homes, and the honest summary is modest. It isn’t a proven cure for hair loss. Some people enjoy using it and feel their scalp is healthier. Others get itching, redness and a smell that returns every time the hair gets wet. If you’d like to try it, do it carefully. The same onion carries a second set of household claims in summer, weighed up in our piece on raw onion and the loo.
- Patch test first: dab a little juice behind the ear, leave 20 minutes, rinse, check the next day.
- Peel and roughly chop 1 medium red onion (about 150 g).
- Blend with 2 tablespoons of water and squeeze through a clean muslin cloth. You’ll get roughly 4 to 5 tablespoons of juice.
- Dilute half and half with water or aloe gel for a first try.
- Dab onto the scalp only with cotton, parting by parting. Keep it well away from the eyes.
- Leave 15 to 20 minutes, not overnight, then shampoo out.
- Use once or twice a week at most. Discard leftovers; don’t store the juice.
Stop at once if it burns, itches badly or leaves the scalp red.
Oiling: what it does and doesn’t do
A weekly oil massage softens dry lengths, reduces friction and tangles, and so reduces breakage. A nightly detangle before sleep does the same small job on the days in between. It feels calming and is a genuine family ritual. It doesn’t reverse hereditary thinning or make up for low iron. Our step-by-step mustard oil champi guide covers technique, so just a few rules here:
- Use about 1 to 2 tablespoons for shoulder-length hair. More isn’t better, it just needs more shampoo.
- Warm the oil slightly (comfortably warm on the inner wrist, never hot).
- Massage with fingertips, not nails. Don’t pull hair into a tight bun afterwards.
- Leave 1 to 2 hours or overnight, then wash. If you have dandruff, heavy oil left for long can make flaking worse; see our dandruff home remedies.
- Coconut oil suits many hair types; mustard oil is warmer and stronger smelling; amla oil is traditional. Choose what your scalp tolerates.
A soaked methi seed rinse is another option many families use; we’ve covered it fully in methi for hair.
Unani writers linked hair loss to dryness and imbalance of the humours and favoured oils considered moistening, such as almond and sesame, along with head massage. Ayurveda traditionally associates early greying and hair fall with excess heat and recommends cooling oils such as those infused with amla, bhringraj or hibiscus, and routine scalp oiling as part of self-care. These are traditional frameworks, not medical diagnoses.
Protein and the everyday plate
Hair is made mostly of protein, and crash diets or long periods of eating very little often show up as shedding a couple of months later. You don’t need powders. You need enough, spread across the day.
- Include a protein food at each main meal: dal, chana, rajma, eggs, dahi, paneer, chicken, fish.
- Pair iron-rich vegetarian foods (chana, palak, lobia) with a vitamin C source like tomato, lemon or amrood.
- Don’t drink tea right with meals if you’re low in iron; leave about an hour gap.
- A handful of peanuts, roasted chana or a boiled egg makes a simple snack.
If you have kidney disease, diabetes or are on a special diet, check with your doctor or a dietitian before increasing protein significantly.
Everyday handling that saves more hair than remedies
- Detangle from the ends upwards with a wide-tooth comb, not a brush, while hair is wet.
- Skip tight ponytails, rubber bands and heavy clips; use soft scrunchies.
- Pat hair dry with a cotton t-shirt instead of twisting it in a towel.
- Keep blow dryers and straighteners on low and occasional.
- Go gentle with harsh shampoos. Some people like homemade washes; our guide to reetha, shikakai and rice water covers the honest pros and cons.

Hair fall questions people ask
How much hair fall is normal in a day?
Everyone sheds some full-length hairs every day, and a few dozen on a wash day is ordinary. What matters is a sudden, clear increase, handfuls in the shower, or a widening parting. If that lasts more than about 3 months, it’s worth seeing a doctor.
Does onion juice really stop hair fall?
It isn’t a proven hair loss treatment. Some people like how their scalp feels after it, others get itching, redness and a smell that comes back whenever the hair gets wet. If you try it, patch test first, dilute it, leave it on 15 to 20 minutes only and stop if it burns.
Can I apply onion juice every day?
That’s not a good idea. Daily use raises the chance of scalp irritation. Once or twice a week, diluted and washed out after 15 to 20 minutes, is the most to try, and never on a sore or broken scalp.
Does oiling stop hair fall?
It reduces dryness, tangles and breakage, which can make a real difference to what you see in the comb. It doesn’t stop shedding caused by illness, low iron, hormones or genetics. About 1 to 2 tablespoons, warmed slightly, once a week is enough.
Which oil is best for hair fall, coconut, mustard or amla?
Whichever your scalp tolerates. Coconut suits many hair types, mustard is warmer and stronger smelling, and amla oil is the traditional pick. None of them regrows hair, so choose on comfort and smell rather than promises.
Which blood tests should I get for hair fall?
Doctors commonly check a complete blood count, serum ferritin for iron stores and thyroid function (TSH), sometimes with vitamin D, B12 or hormone tests. Your doctor picks what fits your symptoms. If you take biotin, mention it before the blood draw, because it can throw off some results, including thyroid tests.
Can low iron cause hair fall?
Yes, low iron is one of the most common reasons, especially in women with heavy periods. Tiredness, pale skin and breathlessness on stairs are other clues. Get tested before taking iron tablets, since too much iron is harmful.
Should I get my thyroid checked for hair fall?
If hair fall is heavy or lasting, or comes with tiredness, weight change, constipation, dry skin or feeling too cold or too hot, asking your doctor for a thyroid test is reasonable. Both an underactive and overactive thyroid can cause shedding.
Is hair fall after dengue or typhoid permanent?
Usually not. Shedding often starts 2 to 3 months after a high fever and settles on its own over several months as new hair grows. If it doesn’t slow down, or you still feel unwell, see a doctor.
What about hair fall after pregnancy?
It’s very common a few months after delivery and usually improves with time. Keep eating well, keep taking whatever your doctor prescribed, and check with them before using new supplements or scalp products while breastfeeding.
Can biotin tablets help hair fall?
Only if you’re genuinely short of it, which is uncommon. Don’t start biotin on your own, and if you already take it, tell your doctor before any blood test, since it can interfere with results such as thyroid tests.
Does stress cause hair fall?
It can. A big shock, illness or a stressful few months can trigger heavy shedding a couple of months later. It usually settles once the trigger passes, but rule out low iron and thyroid problems if it’s lasting.
Can crash dieting cause hair loss?
Yes. Eating too little, especially too little protein, often shows up as shedding a couple of months later. Include dal, chana, eggs, dahi, paneer, chicken or fish at each meal instead of reaching for powders. Aim for no faster than 0.5 to 1 kg a week if you’re losing weight.
Can PCOS cause hair thinning?
It can. Thinning on the top of the head alongside irregular periods, acne or extra facial hair is a pattern worth showing a doctor, who may suggest hormone tests. Home remedies won’t address the hormonal side.
How long before I see results from hair fall remedies?
Give any routine at least 3 months, because hair grows slowly and shedding lags behind its cause. Less breakage from gentler handling can show sooner. If there’s no change after 3 months, get tested rather than trying more oils.
Is hair loss in children normal?
Not usually. Round bald patches, scaly areas or broken hairs in a child can be ringworm of the scalp or another condition needing treatment. See a doctor rather than trying home remedies, and never put onion juice or strong oils on a baby’s scalp.
Can tight hairstyles cause hair fall?
Yes. Tight ponytails, buns and rubber bands pull at the roots and can thin the hairline over time. Switch to loose styles and soft scrunchies, and detangle from the ends upwards with a wide-tooth comb.
