Shedding vs. Breakage: How to Tell, in Thirty Seconds
This is the most useful distinction in hair, and almost nobody makes it.
Two people sit in the chair with what looks like the same complaint. Hair everywhere. Brush full of it. Something is wrong. One of them has a follicle releasing hair on schedule. The other has hair snapping in half two inches from the ends. Those are opposite problems with opposite solutions, and treating one as the other wastes months and money.
The good news is that you can tell them apart yourself, tonight, with a lamp and about thirty seconds.
The test
Pick a hair off your shirt, or off the brush, or out of the drain. Hold it up against something dark and get a light on it.
Look at both ends.
A shed hair has a bulb. A tiny, slightly swollen, usually pale or whitish node at one end. That is the root end, and it means the entire hair came out of the follicle intact, at the end of its cycle, exactly as designed. The other end will be your normal hair end — blunt if you have a recent cut, tapered if you don't.
A broken hair has no bulb at either end. It has two ends that both look like ends — blunt, ragged, or frayed and splitting into fibres. It never left the follicle. It failed somewhere along its own length, and the rest of it is still on your head.
That is the whole test. Bulb or no bulb.
The second test, which is even easier
Look at the length of what you are finding.
Shed hairs are the length of your hair. All of them, roughly. If your hair is to the shoulder, the hairs on your pillow are to the shoulder.
Broken hairs are short and wildly inconsistent — two inches, five inches, an inch, seven inches. A pile of ragged, varied, short pieces is breakage and it is not ambiguous once you have seen it.
You can also see breakage on your head rather than off it. Stand in front of a mirror in good light and look at the top of your head against a dark background. A halo of short, wiry hairs standing up all over the crown is one of two things: new regrowth, or a field of snapped-off ends. Regrowth tapers to a fine point. Breakage does not — it ends abruptly, like a cut wire.
Why this matters more than anything else on this page
Because the remedies do not overlap at all.
Breakage is a mechanical and chemical problem. It is caused by what you do to your hair, and it responds to changing what you do. Better technique, gentler tools, less heat, fewer processes. Results are relatively fast, because you stop the damage and grow past it.
Shedding is a biological problem. It happens at the follicle, below the skin, and nothing you apply to the hair itself reaches it. A shedding problem is a body problem — hormonal, nutritional, medication-related, stress-related, or simply the cycle doing its job. Products applied to the strand cannot touch it.
So: do not buy a brush for a shedding problem. I sell brushes. I still would not sell you one for that, because it will not work and you will conclude that brushes are a scam, and you will be right about that particular purchase.
What actually breaks hair
Twenty-three years of looking at it. In rough order of how often I saw it:
Brushing wet hair from the roots down. The worst habit, the most common, and the easiest to fix. Wet hair swells, and swollen hair stretches — it will extend noticeably further before it fails than dry hair will. That sounds like an advantage and it is the opposite. It means you can pull it well past the point of damage without feeling any resistance, and it snaps somewhere you are not looking.
Dragging a brush from the scalp downward into a knot. Every tangle you hit becomes a compression point, and you are driving the entire length of the hair into it. Start at the ends. Work up in sections. It feels slower and it is faster, because you are not fighting yourself.
Heat on hair that has nothing left in it. Repeated high heat on already-processed hair, with no protection and no moisture, is a reliable way to produce exactly the field of short broken ends described above.
The elastic in the same place every day. A ponytail worn at the identical height for years breaks hair in a band. You can see it as a distinct short fringe when the hair is down.
Overlapped chemical processing. Colour applied root-to-end every time rather than root-only on the regrowth, so the mid-lengths get processed four and five times over. Bleach on top of a previous bleach. A relaxer or a perm on hair that has been lightened. Each of these on its own is survivable; stacked, they are the reason a client's hair snaps at the exact point where two processes overlapped. I could usually find that line by eye — a band of weakness sitting at a specific distance from the scalp, corresponding to a specific appointment.
Bad tools, honestly. Moulded plastic balls on the ends of bristles that have chipped or come off, leaving a sharp stub. Seams down the middle of an injection-moulded barrel that catch and saw. Bristles set at a density that packs hair against the barrel rather than passing through it. This is a real cause and it is the one the industry is least honest about, because it is the industry's own fault.
What a brush can and cannot do
I want to be precise here, since I make them.
A brush cannot cause pattern hair loss. It cannot cause thinning at the crown, recession at the temples, or a widening part. Those are follicle events happening below the surface and a brush does not reach them. If someone tells you your brushing caused pattern loss, they are wrong.
A brush absolutely can cause breakage, and a bad one causes a lot of it.
And sustained tension can cause a real hair loss — traction alopecia, at the hairline and temples, from styles pulled tight over long periods. That is tension, not the tool, and it is worth knowing about because caught early it recovers and left long enough it may not. If your hairline is receding and your hair is habitually worn tightly pulled back, that is a doctor conversation, not a product conversation.
So the honest scope of what a better brush does: it removes one common source of mechanical damage. That is genuinely worth something if breakage is your problem. It is worth nothing at all if it isn't.
The habits that actually fix breakage
Short list, all free.
- Detangle from the ends up, in sections, always. This single change does more than every product I have ever sold.
- Be gentler when wet than when dry, not the reverse.
- Move the elastic. Different height, different day.
- Clean your brush weekly. A brush packed with old hair and product stops passing hair through cleanly and starts pulling it. Details in How to Make a Brush Last.
- Give it a haircut. Split ends travel upward. Nothing seals them, whatever the bottle says. Removing a quarter inch every couple of months is the only real answer and it is the one people resist hardest.
If it turns out to be shedding
Then this page is the wrong page and I would rather say so than sell you something.
Start with The Hair Growth Cycle, Explained Plainly to work out whether what you are seeing is the cycle behaving normally. Then Why It Started Three Months Ago, because shedding almost always has a cause sitting further back than people look.
And if it is sudden, patchy, or comes with an itchy, scaling, sore or inflamed scalp — that is a doctor, promptly. I sent plenty of clients to one and never once regretted it.

What to do next
If it is breakage, it is mechanical and you can fix it: how you handle a brush, what chemical processing does, and how you dry it. If it is shedding, read why it probably started three months ago, then what actually works now.
