How to Prevent Hair From Matting.

Daily Care Guide · London

To prevent hair from matting, detangle gently from the ends up to the roots, often enough that shed hair leaves your head before it wraps around the strands still growing. That one habit does the most. The other four below look after the ends, the night, shed hair and any braids or weaves.

If your hair is already matted, skip to what to do tonight.

The short answer

What Causes Hair to Mat?

Hair mats when shed strands stay in your hair instead of falling away. They wrap around the strands still growing from your scalp and catch more shed hair. Friction then pulls that loose knot tight, and it hardens into a mat.

You shed 50 to 100 hairs a day. If none of them is combed out, that is 150 to 300 trapped strands in the first three days, 350 to 700 by the end of the first week, and up to 2,800 by the fourth week.

Dry ends, friction from pillows, collars and hoods, long gaps between detangling and styles left in too long all speed this up, and each has its own habit below. If your hair knots faster than other people's even with a good routine, the reasons some hair mats so easily are worth checking in order.

In my case files, the largest share of matting, 42%, followed depression, illness and hospital stays. Wrong washing technique is the second most common cause, at 13%. Skipped brushing routines are cause number three: 10% of the matting I have treated since 2020, around 100 heads.

The Five Habits That Prevent Matting

You do not need to start all five at once. Begin with the one you skip most often. If you are running the routine for someone else, the carer's guide to matted hair in older people covers the nape check and the night.

Detangle from the ends up, before you wash

Start at the ends and work up towards the roots, so every knot opens from below. Do it before you wash, not after. Use your fingers or a wide-tooth comb, and if you would rather use a brush, pick one that will not snag. The American Academy of Dermatology gives the same advice: comb gently, and only to style.

Keep the ends moisturised

The ends dry out first, so that is where the moisture goes. Frizzy, rough ends are the early sign that strands have started to catch on each other. Work a leave-in conditioner or a light moisturiser into them; the guide on how to use a leave-in conditioner on the ends shows the method.

Protect your hair at night

In my case files, sleep friction and fabric damage account for 4% of my clients, so the night is rarely the main cause. It is where a small tangle gets tight, though. Swap a cotton pillowcase for silk or satin, or plait or wrap your hair loosely before bed. Do not go to bed with wet hair, loose or tied up: it tangles heavily overnight.

Comb shed hair out before it knots

Pull the loose strands out of your comb or brush each time you detangle, and pick out the ones that come away while you wash, so they do not settle back into the lengths and wrap round the growing hair.

Take braids, twists and weaves down in time

Braids, twists and weaves protect the hair for a while, but shed hair keeps building up under them. Take them down and redo them on time. Hair left styled too long mats underneath where you cannot see it. Around 30% of my London clients arrive with extension-related matting.

Preventing Matting by Hair Type

Fine and straight hair: the knots usually turn up at the nape and behind the ears while the rest stays smooth. A quick comb there every day keeps them from building. If it is always the same spot, read why the nape mats before the rest of your hair.
Wavy and curly hair: needs more moisture, and for curls 'before you wash' means in the shower, on damp hair with conditioner in, before you rinse. My curly hair routine that keeps curls from knotting sets out the order.
Afro and 4C hair: mats fastest because of the tight coil pattern. Detangle in sections with plenty of slip, meaning conditioner or a detangler that lets your fingers glide, and protect it carefully at night. If a section has already matted, my guide to detangling matted afro and 4C hair covers what to do.
Long hair of any type: tie it up loosely for sleep and exercise so it does not rub into knots.

If your hair is not matted, normal care still applies. There are two ways to detangle healthy hair and I use both: damp, with a detangler spray or a liquid treatment, and dry. Which one suits you depends on your texture, the condition of the hair and how it behaves when it is handled, and an article cannot read that for you. Send a photo and I will tell you which of the two to start with.

Common Mistakes That Cause Matting

Skipping detangling for days, then trying to fix a week of tangles in one go.
Ripping through knots instead of easing them apart. It snaps the hair, and every snapped piece is one more loose strand to tangle.
Washing with the hair piled on top of your head instead of letting it hang down.
Heavy oils or product build-up, which can glue shed hair into place. Avoid olive oil in particular.

When Matting Has Already Started

If a mat is already there, you do not need to fix it tonight, only to stop it getting worse. The mirror does not always show whether hair is tangled or matted, so test it with your fingers: pinch a dry section and ease the strands sideways, without pulling. Strands that slide apart, however slowly, are tangled, and the routine above still works. If the section moves as one felted pad, it is a mat. Stop the routine there.

Keep the matted part dry and put nothing on it, including conditioner, oil and detangler spray. Water and product both tighten and weigh down a mat.

Gather the loose hair around the mat into several small, loose three-strand plaits, so it does not get drawn into the mat while you sleep.

Then send me a photo of the matted part on WhatsApp. I usually reply within an hour.

A mat that pulls on the scalp or covers a large area needs opening by hand, and that is the work of matted hair removal in London. Of my clients since 2020, 99% were saved without cutting.

Frequently Asked Questions

Why does my hair keep matting?

Look at the patch that mats first, because matting that keeps coming back usually returns to the same place. Check how that patch is washed and what it rubs against at night, then change one thing at a time so you can see which one mattered. A patch that knots again within days of a careful detangle is worth showing to a specialist.

How often should I detangle to prevent matting?

For most hair types, gentle detangling every one to two days prevents matting. Very curly or coily hair benefits from detangling at every wash as well, with plenty of conditioner. If you find new knots before the next detangle is due, the gap is too long for your hair, so shorten it.

Does sleeping cause hair to mat?

Yes, mainly through friction. Hair moves against a cotton pillowcase for a whole night, and that rubbing pulls loose tangles tighter. A pillow mostly tightens tangles that were already there, so a gentle detangle just before bed does more for your hair than the choice of pillowcase.

Can dry hair cause matting?

Yes. Dry hair has a raised, rough cuticle, the outer layer of each strand, and it catches on neighbouring strands instead of sliding past them. That is why dry hair looks frizzy before it tangles, and why it mats more easily than moisturised hair. When the ends feel rough, put a little leave-in on them that day rather than waiting for the next wash.

How do I stop my hair matting at the back of the neck?

The nape mats first because it rubs against collars and pillows and is the part most often missed when brushing. Check it every day: lift the hair at the back, run your fingers through the underneath layer from the ends up, and keep a little leave-in on it. At night, a loose plait keeps it from rubbing.

What should I do if my hair is already matted?

Do not cut it, and do not try to open it at home with water or product. A mat is opened dry, strand by strand, and that is the work of professional dematting. All of the work is done by hand. I use my fingers, special tools, sprays and products, each only when the hair needs it.

Does detangler spray stop hair from matting?

Not on its own. On hair that still separates, a detangler adds slip, so fingers and a comb glide through instead of snagging and snapping strands. The shed hair still has to be combed out. On a mat, a detangler is never the first thing: slip product goes on only once a section has started to open.

Hair Matting Despite Your Best Efforts?

If you have kept to the routine and your hair still knots, it is no one's fault. Show me the patch that keeps matting: the earlier I see it, the less there is to open.
