White Dots on Hair Ends: Breakage or Nits? Table and Trim

The white dots on your hair ends are breakage in its earliest stage, known medically as trichorrhexis nodosa: at that spot the cuticle has rubbed away, the fibre is fraying inside, and that is where it will snap next. The only way to get rid of a dot is with scissors, half a centimetre above it; new ones you head off with less friction, less heat and conditioning care through the lengths. Your freshly trimmed ends tell you whether that is enough: if they stay smooth over the next few weeks, you have found the cause.

What the white dots at the end of your hair are: trichorrhexis nodosa

Every hair is sheathed in a layer of overlapping scales, the cuticle, which sits over the inner fibre like roof tiles. Where it gets rubbed away, the bundles of fibre underneath are exposed, splay apart and scatter the light. To the naked eye that shows up as a tiny white or pale grey knot that feels rough between your fingers. Under a microscope the spot looks like two paintbrushes pushed into each other, bristles first.

At the knot, the fibre can barely take any pull. Sooner or later it snaps there, while you comb, tie a ponytail or blow-dry, and what remains is a frayed end that carries on splitting. So the dot is the stage before a forked end. Once the end has forked, the damage is called a split end, and the same rules apply, one step later.

There is a simple reason the dots almost always sit in the last few centimetres. Hair grows about a centimetre a month, so on shoulder-length hair the ends are two to three years old. They have been through hundreds of washes, brush strokes and blow-dries, and they have no way of renewing themselves.

White dots on your hair but no lice? How to tell them apart

Six different things look white in hair, and each one calls for something different. Take a strand between your thumb and index finger and slowly slide them down it. Anything that moves along with your fingers sits loosely on the hair. Anything that stays is part of the fibre or glued firmly to it.

If you find nits, lice are involved. A pharmacist can advise you on treatments and on combing them out with a nit comb, and for a child the GP surgery can help too. Flakes belong to the scalp, and comparing dry scalp or dandruff helps you work out which of the two is behind them. The pale bulb at the root end shows a hair that came out complete with its root. Broken hairs never have one, and that detail also tells you whether you are looking at breakage or hair loss.

If your whole ends look whitish and duller than the lengths above them, instead of showing single dots, the cuticle has roughened over a wider area. Sun, chlorinated water, grown-out bleach or a lot of heat leave white ends like these. If the first row of the table matches your ends, the free hair analysis goes through your styling and care habits one by one.

Where the dots come from and what to change

Usually several kinds of strain add up. Check them in this order, because the first two cost nothing except a new habit.

Pull a brush through tangled hair from the top and it pushes the knots down and tears them open at the ends. Hair ties, clips and a rough pillowcase rub at the same few centimetres, and avoiding mechanical hair damage mostly comes down to small changes in how you handle your hair. Whether heat plays a part for you shows in the signs of heat damage: lost shine, a straw-like feel and ends that no longer blow-dry into shape.

How to get rid of white dots yourself: the twist technique

Between two salon appointments you can remove single dots yourself. All you need is a pair of sharp hairdressing scissors. Craft and nail scissors crush the fibre and leave a new rough edge.

1. Wash your hair, let it dry and comb it smooth. Dots are easier to see on dry hair, and curls tighten up further as they dry.
2. Sit by a window. In daylight the pale knots stand out most clearly.
3. Take a strand about one centimetre wide and twist it firmly in one direction until it looks like a cord.
4. Run two fingers down the cord from top to bottom. Broken and roughened ends now stick out to the sides.
5. Snip off only those sticking-out ends, each one half a centimetre above the white dot. Leave the twisted cord itself as it is.
6. Twist the strand the other way and repeat, then move on to the next strand.

The line of your ends stays a job for your hairdresser. If the dots sit close to the tips of many strands, a trim of half a centimetre to a centimetre is quicker and more even than working strand by strand. If you are growing your hair, a mini trim like that every ten to twelve weeks is usually enough; how often to cut your hair shifts with your length and your goal.

Care that stops new dots forming

This routine protects the last few centimetres from friction and drying out. The amounts are for shoulder-length hair; for chest-length hair, use about twice as much.

Step 1 — Wash. Shampoo goes on the scalp only, with lukewarm water. The lengths get cleaned as you rinse. Lather the ends as well and rub them together, and you roughen the very cuticle you want to protect.

Step 2 — Condition. Work a hazelnut-sized amount of conditioner through the lengths and ends from chin level down, leave it on for two to three minutes and use that time to detangle with your fingers. Once a week a mask replaces the conditioner; for bleached or often straightened ends that could be MONAT's Replenish™ Masque.

Step 3 — Protect. Towel-dried hair gets a leave-in, a conditioner that stays in your hair. Rub a pea-sized amount between your palms and work it in from ear level down only, for example the Bond IQ™ Peptide Therapy Leave-In Cream. Before the hairdryer or straightener comes a heat protectant, sprayed evenly over the lengths and combed through once.

Step 4 — Finish. Rub one or two drops of REJUVENIQE® oil between your palms and press it into the ends only. If your ends feel stringy rather than soft afterwards, that was too much, and one drop will do next time. If the ends stick out and look rough, REJUVABEADS® smooths their appearance through the mid-lengths and ends for a while. That won't remove a white dot either.

Home remedies and myths: what works?

• Burning them off with a candle: skip it. The flame melts the ends into a brittle edge instead of sealing them, and you risk burning your hair and skin. Salons call the same idea candle cutting, and there too, scissors leave the smoother edge.
• Oil helps as prevention, whether coconut, argan or almond. It makes the ends more supple, so they rub less as you comb. It does nothing to a dot that is already there.
• Split end serums wrap the ends in a film. They feel smoother and look better groomed until the next wash, while the break underneath stays.
• Egg, mayonnaise or beer masks do no harm. For the dots, though, they achieve nothing an ordinary conditioner can't.
• Biotin and other supplements change nothing at the ends. That hair grew years ago, and the root no longer supplies it.

What you see after one wash, four weeks and three months

After the first wash with leave-in and oil, the comb glides through your ends more easily and they snag less. The white dots are still there. Oil and leave-in make them a little less obvious; they only go once they are cut off.

After four weeks, the strand check shows whether you have found the cause. At the start, snip off the dots with the twist technique and pick three strands to keep track of: left, right and back. Four weeks later, check the same three in daylight. New dots on the freshly cut ends mean a trigger is still at work, often heat or brushing wet hair.

After three months your hair has grown about three centimetres. A photo of your ends from the side, taken every four weeks at the same window, shows whether the line stays even or starts to fray again. If it frays, go through the table of triggers again, row by row.

When a dermatologist should take a look

At the ends, trichorrhexis nodosa almost always comes from care and styling. See a dermatologist if the knots also appear close to the scalp or along the whole length, if your hair breaks off a few centimetres from the scalp although you handle it carefully, or if a child is affected. The dermatologist looks at the hairs under a dermatoscope and uses blood tests to check whether something like an underactive thyroid, iron deficiency or, in children, an inherited metabolic disorder is involved.

Quick questions

Can I just pick the white dots off?

No. Tear the fibre at the knot and you are left with a frayed end like a tiny brush, which keeps splitting. Scissors cut higher up in intact hair and leave a clean edge.

Are white dots on hair ends the same as split ends?

Almost. The white dot is the stage before: the fibre has already frayed inside but has yet to fork. Once it snaps at the knot, it turns into a split end, known technically as trichoptilosis.

Are white dots in hair contagious?

No. The knots at the ends are damage to the fibre itself. Lice are what spread, and their nits are glued firmly to the hair shaft close to the scalp.

Do men get white ends on their hair too?

Yes, once their hair reaches about chin length. Short hair is cut every few weeks, so its ends are young. White dots in short hair point to heavy strain such as bleaching, and if you can see no reason for them, have a dermatologist look.
