Hair Breakage vs Hair Loss: How to Tell the Difference
12 min read Care know-how Updated 5 October 2026 By Anna Sophie Schulenburg
Whether it's hair breakage or hair loss shows at the end of the hairs you find. A hair that has fallen out is almost as long as your haircut and has a tiny pale bulb at one end: the root. A broken one is shorter and ends frayed or blunt. Today, collect ten hairs from your brush and the plughole and lay them on a towel that contrasts with your hair colour. If short pieces without a bulb outnumber the rest, start with the fibre and cut back on heat, tension and friction. If whole hairs with a bulb make up most of the pile, keep an eye on the amount over the next few weeks.
What you're looking at: a root or a break
Every hair goes through a cycle. In the growth phase, called anagen, the root pushes the hair out of the scalp for several years, at roughly a centimetre a month. After a short transition, the hair sits loosely in the follicle for about three months. That is the resting phase, telogen. Then it falls out, and a new hair grows from the same follicle.
A hair that has fallen out carries a round, whitish bulb at its end, tiny but visible to the naked eye. All it tells you is that the hair has finished its cycle. Every hair lost through normal shedding comes out with this bulb.
A hair pulled out in the middle of its growth phase looks different, for example when you tear through a knot or wear a very tight ponytail. Its root is elongated, often darker, and sometimes a glassy sheath hangs from it. If you find hairs like this often, something is usually pulling too hard at the roots.
With breakage, the fibre snaps somewhere along the shaft. The root stays in the scalp and keeps growing. At the break you'll see a frayed, forked or kinked end, sometimes with a white dot just before it. Those white dots on the hair ends mark the places where the fibre will snap next.
How do I tell hair loss from hair breakage?
Three tests are enough. The first takes two days, the other two a few minutes.
- For two days, collect the hairs from your brush, the plughole strainer and your pillow. Hold them next to a strand: nearly as long as your haircut means shed, clearly shorter and of different lengths means broken.
- Look at both ends in daylight, using your phone camera's zoom if you need to. A pale bulb at one end is the root. On a broken piece, one end is the old tip and the other is the break, and neither has a bulb.
- Do the pull test, no sooner than a day after washing, because otherwise the loose hairs have already gone down the drain. Close to the scalp, take a bunch of about 50 to 60 hairs between thumb and index finger and pull with light, steady tension all the way to the ends. Repeat along your parting, at both temples and at the back of your head.
In a pull test, one to three hairs per bunch normally come away in your hand. If it's more than six in several places, and they all have a bulb, you're shedding more than usual at the moment. Count short pieces without a bulb as breakage.
| What you find | Points to breakage | Points to hair loss |
|---|---|---|
| Length of the hairs | Short pieces of different lengths | Nearly as long as your haircut |
| The end | Frayed, forked or kinked, often with a white dot just before it | Small pale bulb at the root end |
| Pull test | Pieces without a bulb come away in your hand | More than six whole hairs per bunch |
| Where you notice it | In the ends, at the height of your hair tie, short hairs sticking out along the lengths | In the brush, the plughole and on the pillow, spread over the whole head |
| At the roots | Density unchanged, the length makes no progress | Parting wider than before, more scalp showing |
| Your ponytail | Gets thin and wispy towards the ends | Is already slimmer at the hair tie |
| History | Bleach, colour, straighteners, tight styles | Fever, giving birth, a diet, stress or a new medication two to three months earlier |
Both can happen at once, for example severe breakage on thinning hair that gets styled and coloured more often. If your hair is breaking and falling out, sort the two separately: hairs with a bulb on one side, pieces without on the other. If several rows in one column fit you, the free hair analysis asks about these observations and your habits one by one.
100 hairs a day: is that true?
The number is an average, and you can do the maths yourself. A head has roughly 100,000 hairs. About one in ten is in the resting phase at any time, and that phase lasts around three months. Roughly 10,000 hairs spread over 90 days makes a little over 100 a day. Someone with naturally more hair also loses more, and the amount varies from day to day anyway.
Still, the number is of little use for counting. If you only wash every three days, three days' worth of hair ends up in the plughole on wash day, and that can easily look like 200 or 300. In late summer and autumn, many people shed more for a few weeks; whether you're dealing with seasonal hair loss in autumn shows over time.
Comparing with yourself tells you more than any daily figure. On two wash days a week apart, take the hairs out of the plughole strainer and compare the amounts. If it stays clearly higher than before for six to eight weeks, or your ponytail gets slimmer, more is falling out than growing back.
Colour, heat, tension: where breakage comes from
Usually several stresses add up. The first two rows only cost you a new habit.
| Trigger | How to spot it | What to change |
|---|---|---|
| Brushing wet and rubbing | Knots, short pieces in the comb right after washing | Detangle wet hair with a wide-tooth comb from the ends upwards; squeeze the towel instead of rubbing |
| Heat | Straw-like feel, straighteners above 180°C, dryer on the highest setting | Heat protection before every styling, dryer on a medium setting at 15 cm, straighteners at 180°C at most, lower for fine or bleached hair |
| Colouring and bleaching | Breakage at the line between regrowth and old colour, or in the lightest strands | Have only the regrowth treated when you recolour; at least six weeks between two chemical treatments |
| Tension | Snapped hairs at the height of your hair tie, under clips, along the hairline | Tie your ponytail loosely and at a different height every day; spiral hair ties without metal parts |
| Friction | More breakage on one side, or at the height of a collar, scarf or backpack strap | Plait long hair loosely at night; a satin or silk pillowcase |
With permanent colour and bleach, the alkaline agent opens the cuticle and the hydrogen peroxide attacks pigment and bonds inside the hair. It gets critical when the same lengths are coloured again at every appointment or bleach goes on top of old colour. Then the hair often snaps along the line where the treatments overlap. How you care for bleached hair against breakage comes down to mild washing, moisture through the lengths and as little heat as possible.
Tension, friction and wet brushing come from movements you repeat every day. If you want to avoid mechanical hair damage, start with your comb, your hair ties and your pillowcase.
What helps with breakage in the middle of the lengths?
If the hair breaks halfway down rather than at the ends, the trigger almost always sits at one fixed spot. Run your fingers along the strands and find the height where the breaks cluster. If it's where your hair tie, claw clip or straighteners sit, you've found the cause. If it runs like a line around your head, it's usually the edge of an old colour or bleach.
Broken sections don't grow back together. At your next salon appointment, have the hair cut past the break zone, or into layers if you want to keep the length. Then take out the trigger: a ponytail at varying heights, straighteners pulled through the strand in one pass without pausing at any spot. If the zone is too long to cut off, the routine in the next section keeps the lengths supple until it has grown out.
Short hairs sticking up on top of your head and along your parting can be broken or just growing back. Typical triggers for breakage at the crown are tight buns, claw clips and straighteners used close to the roots. Snapped hairs end bluntly; new ones taper to a point.
Care against breakage: four steps for the lengths
The amounts are for shoulder-length hair. For chin-length hair use about half, for chest-length twice as much.
Step 1 — Wash. Shampoo goes on the scalp only, worked in with lukewarm water and your fingertips. The lather running off cleans the lengths. For breakage-prone hair, MONAT's Bond IQ™ Fortifying Shampoo is one option, a walnut-sized amount.
Step 2 — Condition. Apply a walnut-sized amount of conditioner from ear level through the lengths and ends, for instance the Bond IQ™ Fortifying Conditioner. Leave it on for two to three minutes and detangle with your fingers in the meantime. Once a week, a mask replaces the conditioner.
Step 3 — Protect. Towel-dried hair gets a leave-in, meaning a product that stays in the hair: a pea-sized amount from chin level, for example the Bond IQ™ Peptide Therapy Leave-In Creme. Before using a dryer or straighteners, spray a heat protectant such as the Studio One™ Thermal Protect Shield evenly over the lengths. If the lengths then hang lank rather than soft, that was too much leave-in; next time half will do.
Step 4 — Finish. If the ends stick out and feel rough, REJUVABEADS® temporarily smooths their look. Only scissors remove what has broken. In the evening, plait long hair loosely so it rubs less while you sleep.
When whole hairs fall out: what may be behind it
If more whole hairs with a bulb are falling out, the trigger lies at the root or in the body, and caring for the lengths won't change that. A common pattern is temporary shedding two to three months after a high fever, giving birth, an operation, a strict diet or a very demanding period. Many hairs then switch to the resting phase at the same time and fall out with a delay.
Hereditary thinning progresses more slowly and lasts; in women it typically shows as a widening parting while the hairline at the forehead stays put. There are medical treatments for it, and the earlier they start, the more hair is still there to keep. That's why a widening parting belongs with a dermatologist early on. How to wash and style thinning hair so it falls fuller is something you can work on alongside.
If you use MONAT: the shampoo and conditioner from the IR Clinical™ system are designed for hair that looks thinner and give the hair you have more fullness to the touch. They don't make new hair grow, and they don't replace a medical check either.
Myths and home remedies, with a verdict
- Cutting more often makes hair grow faster: false. The root knows nothing about the scissors. Cutting removes broken ends, and because less snaps off afterwards, your length makes better progress.
- Washing less often doesn't slow hair loss. Washing only loosens hairs that were already sitting loose in the resting phase. Wash less often and you'll simply find them all together on wash day.
- A hundred brush strokes in the evening won't make hair stronger. Every stroke rubs against the cuticle and can encourage breakage. Brush until the hair is detangled, then stop.
- Two to three drops of oil on dry ends help with combing, because the comb catches less. The oil won't make brittle spots strong again.
- Biotin for breakage only helps with a proven, rare deficiency, and your lengths grew months ago anyway. High-dose biotin can also skew lab results such as thyroid values. So mention it before a blood test.
What you'll see after one wash, four weeks and three months
For breakage, check after the first wash with leave-in whether the comb glides through more easily and fewer short pieces get caught in it. After four weeks, repeat the collection from the first test. If fewer short pieces lie on the towel, you've caught the trigger. After three months, around three centimetres have grown, and at a freshly cut edge you can see whether the ends stay smooth.
Temporary shedding after a stressful event usually settles within three to six months. After that, short new hairs often appear along the parting and the hairline. You tell them apart from broken pieces by the end: new hair tapers to a point, while a snapped one ends blunt or frayed.
When to see a dermatologist
Shedding for a few weeks after a clearly identifiable stress is something you can watch. With these signs, book a dermatologist soon, because they can point to treatable causes that only a clinic will find:
- round bald patches, even small ones, or hair coming out in clumps
- clearly increased shedding that lasts longer than three months
- a parting that visibly widens within a few months
- a scalp that hurts, burns, weeps, is red or flakes heavily
- shedding that started after a new medication; don't stop taking it on your own, and talk to the practice that prescribed it
- tiredness, feeling cold, a change in weight or a change in your period on top
Ask your dermatologist or GP for a full blood count, ferritin, which shows your iron stores, and the thyroid value TSH.
What care can do
Support cleansing, conditioning, manageability, shine, frizz control, protection from avoidable breakage and a fuller-looking appearance, depending on the product and its substantiated claims.
What it cannot do
Diagnose disease, correct hormonal causes, create new follicles or permanently fuse fully split hair ends.
Right away
Right after use, the lengths can feel softer and more textured and existing hair can look fuller.
With continued use
With regular cosmetic care, avoidable breakage can go down over a few weeks and hair can look stronger and denser.
What it can't do
Cosmetics don't trigger new hair growth, don't distinguish breakage from true hair loss and don't treat a medical cause; for sudden, patchy or persistent loss please see a doctor.
Quick questions
Can hair break right at the scalp?
Yes. Under tight ponytails, at extensions and with straighteners used close to the roots, hair sometimes snaps a few millimetres above the scalp. It then looks like hair loss, and a look at the end settles it: the pieces have no bulb.
Does broken hair grow back?
Yes, the root keeps working as before. The frayed break doesn't join back together. It moves down with the hair and disappears at your next cut.
Can colouring cause hair loss?
No, as a rule it can't. Colouring weakens the fibre and can lead to breakage. It doesn't reach the root. The exception is an allergic reaction to a dye. If your scalp itches, burns or swells after colouring, see a dermatologist, and before your next colour an allergy test there will show which substance is responsible.
Does iron deficiency cause breakage?
More likely shedding. Low iron stores are mainly linked to more whole hairs falling out. Only a blood test shows whether your ferritin is low, and taking iron tablets on a hunch can do harm, because too much iron puts a strain on the body.
Does brittle hair need protein or moisture?
A wet hair you stretch carefully will tell you. If it snaps straight away, it's more likely short of moisture. If it stretches far like a rubber band and doesn't spring back, it lacks structure, and a protein treatment suits it better.
