Hair Loss: Causes & Treatment
Dermatologist-led overview of how hair loss is evaluated and the evidence behind common treatments.
View AAD reference ›They look similar in the basin, but they're two different problems. Hair fall is shedding from the root — you see whole strands, often with a tiny bulb or white tip. Hair breakage is hair snapping along the shaft — short, broken pieces of different lengths, with split or frayed ends and no bulb. The distinction matters because the fixes differ: breakage is largely a cosmetic and hair-care issue (heat, chemicals, rough handling, dryness), while hair fall may have a medical cause — telogen effluvium, pattern loss, deficiency, thyroid, PCOS — that needs assessment. No product cures either, and damaged hair isn't "regrown". Work out which you have first: screen with the AI Hair Test, and see a doctor for sudden, patchy or unexplained shedding. Results vary.

Hair fall is shedding from the root; hair breakage is hair snapping along the shaft. With hair fall you tend to see whole strands, often with a small bulb or white tip at the end, coming away from the scalp. With breakage you see short, broken pieces of varying lengths, with split or frayed ends and no bulb. They're different problems with different fixes. Breakage is usually about damage and dryness — heat styling, chemical treatments, rough handling, tight styles — and is largely cosmetic, helped by gentler care and conditioning. Hair fall can have many causes, some medical — a temporary shedding phase, pattern loss, iron deficiency, thyroid problems, PCOS — so it may need assessment rather than a product. Crucially, no product cures either, and broken hair isn't "regrown" — you prevent further damage and let healthy hair grow. Screen with the AI Hair Test, follow gentle care for breakage, and see a doctor for sudden, patchy, unexplained or increasing shedding. Results vary.
Hair fall and hair breakage both leave hair where you don't want it, but they happen at different points. Hair fall is the strand leaving the follicle at the root; breakage is the strand snapping somewhere along its length.
Breakage is mostly a damage and dryness story — heat tools, colouring or chemical treatments, rough towel-drying and brushing, tight hairstyles and friction weaken the shaft until it snaps. It's largely cosmetic and preventable, helped by gentler handling, conditioning and heat/chemical protection. Hair fall is more varied: a temporary shedding phase after stress, illness or childbirth, pattern hair loss, deficiencies like low iron, thyroid issues or PCOS — some of which need medical assessment.
Bottom line: no product cures either, and damaged hair isn't repaired or regrown — you prevent further breakage and grow healthy new hair. For breakage, focus on gentler habits; for shedding, understand the cause, and see a doctor for sudden, patchy, unexplained or increasing hair fall.

| Feature | Hair Fall | Hair Breakage |
|---|---|---|
| Where it happens | At the root (follicle) | Along the shaft |
| What you see | Whole strands, bulb/white tip | Short broken pieces, frayed ends |
| Main causes | Shedding phase, pattern loss, deficiency, thyroid, PCOS | Heat, chemicals, rough handling, dryness |
| Mostly | Can be medical | Cosmetic / care |
| What helps | Addressing the cause | Gentler care, conditioning, less damage |
| Product role | Supportive only | Supportive / preventive |
| Cured by a product? | No | No |
| Regrown / repaired? | Depends on cause | Damaged length grows out |
| See a doctor? | If sudden/patchy/unexplained | If severe/unexplained |
The table is a guide, not a verdict. If you mostly see whole shed hairs, think hair fall and consider the cause; if you mostly see short broken fragments, think breakage and focus on gentler care. Both can occur together, and neither is cured by a product.

Take AI Hair TestDoctor Diagnosis Needed?Breakage is mostly cosmetic, but hair fall can be medical. Don't self-treat — see a doctor first for any of these.
Explore doctor-reviewed categories. Products support care; they don't cure hair loss or repair damaged hair. Prices, ratings, stock and Rx/OTC badges are placeholders populated dynamically.
For breakage, cosmetic care — gentler handling, conditioning, heat and chemical protection, oils and serums — can reduce further snapping and improve how hair looks and feels, but it does not repair already-damaged hair or make it grow faster; the broken length grows out over time. For hair fall, supportive products may help in some situations, but no product cures hair loss, and if there is a medical cause such as a deficiency, thyroid problem or PCOS, products alone will not fix it. Supplements only help where there is a genuine deficiency. We do not fabricate prices, ratings, stock, discounts or reviews; these are placeholders populated dynamically from the database and label. See a doctor for sudden, patchy or unexplained shedding, a widening parting, scalp redness, pus, pain or crusting, or other symptoms. Results vary.

Hair changes slowly, so logging shedding, breakage, ends, density and any triggers over weeks and months gives you and your doctor an honest picture — and flags when shedding needs assessment.
"The single most useful thing I do in these consults is sort out whether someone is shedding or breaking. They feel the same to a worried person, but they're different stories. Breakage is about how the hair is being treated, and it responds beautifully to gentler habits, conditioning and less heat and chemical stress. Shedding from the root is a different question, because it can be a passing phase or a sign of something like a deficiency, a thyroid issue or pattern loss. I never want someone pouring money into repair products when the real issue is shedding that needs a blood test or an examination. So look at the strands, screen yourself, and if it's sudden, patchy, spreading or coming with other symptoms, let me look rather than guessing."

If your concern is mild, early, non-progressive, cosmetic or scalp-comfort related, or you're unsure, and it looks like breakage, focus on gentler care, conditioning and less heat or chemical damage. If it might be light shedding, keep expectations realistic. If your diagnosis is unclear, take the AI Hair Test or AI Scalp Test first.
For moderate shedding, weak hair, dryness, thinning, a widening parting or crown thinning, or a doctor-confirmed concern, breakage care still helps the look, but moderate or persistent shedding should be doctor-guided and the cause assessed. Confirm what's driving it before relying on products; benefit isn't guaranteed.
See a doctor if you have any of: sudden hair fall; patchy hair loss; scalp redness, pus, pain or crusting; severe dandruff or infection; thick scalp plaques; scalp folliculitis or fungal concern; pregnancy or breastfeeding; teenagers; thyroid symptoms; PCOS symptoms; heavy periods or suspected anaemia; rapid weight loss; severe fatigue; side effects from previous products; or an unclear diagnosis. Assessment comes first.

Look at the strands: whole hairs with a bulb point to shedding from the root, while short, frayed fragments point to breakage along the shaft. Breakage is largely a cosmetic, preventable issue helped by gentler handling, conditioning and less heat and chemical damage. Hair fall is more varied and can be medical, so it may need a deficiency check or examination rather than a product. No product cures either, and damaged hair grows out rather than being repaired. Screen with the AI Hair Test to get oriented, follow gentle care for breakage, and see a doctor for sudden, patchy, unexplained or increasing shedding, a widening parting, scalp symptoms, or signs of a thyroid, hormonal or nutritional issue.

Hairs shedding from the root (the follicle).
Hairs snapping along the shaft, not from the root.
If hairs come out with a small bulb at the root, that is shedding (hair fall); if they snap mid-length with no bulb, that is breakage. The causes and fixes are different.
More likely Hair Fall if hairs have a root bulb, more are coming out overall, or there was recent illness, stress or a diet change; more likely Hair Breakage if you see short broken bits and split ends, use a lot of heat or chemicals, and whole-hair shedding has not increased.

This matrix is educational and helps you understand which direction may fit your situation. It does not replace a dermatologist diagnosis. Results vary.
Look at a few fallen strands in good light. A whole hair with a tiny pale or dark bulb at one end points to shedding from the follicle (hair fall). A short, broken piece with no bulb, often with a split or frayed end, points to breakage along the shaft. Doing this over a few days gives a clearer pattern than a single strand.
Add a gentle comb-and-count habit and note whether loss is diffuse (all over) or patterned (temples/crown). Diffuse or sudden shedding is worth screening with the AI Hair Test; patterned thinning is covered under hair loss.
If the issue is true shedding rather than damage, a repair routine will not fix it — find the cause first. Start with the hair-fall-control routine or ask a doctor.
