Baby Hair Loss and Sensitive Skin at Night: A Complete Guide for Australian Parents

The bald patch, the red cheek, and what the fabric beneath your baby actually has to do with either.

Somewhere around the three-month mark, the sheet tells you first. You lift your baby out of the cot and there it is — a fine drift of hair left behind on the mattress, catching the morning light. A fortnight later there is a smooth ring at the back of their head where the hair used to be, and a photograph from six weeks ago that suddenly looks like a different child.

Almost every Australian parent meets this moment. Almost none of them are warned about it first.

Is baby hair loss normal?

Overwhelmingly, yes. In the womb your baby’s hormones run on yours, and at birth that supply stops abruptly. The follicles respond by dropping into a resting phase more or less in unison, which is why the shedding arrives in a wave rather than a trickle. Doctors call it telogen effluvium. Most parents call it alarming, then get used to it.

It usually peaks around three months and resolves without help of any kind. No shampoo, oil, supplement or fabric prevents it, and anything sold on the promise that it will is selling you something. This half of the story belongs to biology, and biology is not taking suggestions.

So why is the patch always at the back?

Because that is where the rubbing happens — and here the story turns, because this half is not fixed at all.

In 1991 Australia began telling parents to put babies to sleep on their backs. It remains one of the most quietly successful public health campaigns this country has run: sudden infant death has fallen by roughly eighty-five per cent in the decades since. Nothing in this article should ever change how your baby is positioned for sleep.

But it does mean a great many hours spent on the back of one small head. And when a baby turns from side to side while settling — which is a sign of healthy development, not distress — the hair at that single point of contact is dragged across whatever is underneath it.

Newborn hair is vellus: fine, downy, and without the internal structure that makes adult hair forgiving. It does not so much fall out as wear through. So the hormonal shed thins everything at once, friction finishes the job in one place, and the result is the ring that parents have long since nicknamed the Friar Tuck.

Does the cot fabric really make a difference?

It makes the difference you are able to make.

Run a finger across a standard cot mattress and it feels perfectly soft, because an adult fingertip is a poor instrument for the job. Under magnification, cotton twill and the polyester blends used to encase most mattresses are anything but smooth. The fibres are short, upright and inclined to catch. Against a hair shaft roughly a fifth the thickness of your own, they behave less like bedding and more like very fine sandpaper.

Then there is the Australian summer, which compounds everything. Babies lose a remarkable share of their heat through the scalp, and a damp head on an absorbent surface is a gripped head. Wet hair snags where dry hair might glide, which is why the bald patch so often arrives with the first properly humid fortnight in February.

Silk or cotton for a cot?

On friction, silk wins and it is not especially close. The filament is continuous rather than spun from short staples, so there is simply less for hair to catch on, and it absorbs a fraction of what cotton does — which keeps the scalp drier through a warm night.

Cotton is not the villain here. It is breathable, washable and perfectly safe, and generations of babies have slept soundly on it. It is just that its texture is working against fine hair while your baby sleeps, and there is an alternative that isn’t.

If you go looking, you will meet the word momme, and it is worth a moment. It comes from the monme, an old Japanese unit of mass equal to 3.75 grams, and it has been used to weigh silk for centuries — one of those measurements that survived every attempt at metrication because the trade simply refused to give it up. The higher the number, the more silk in the cloth. Lightweight silks around 16 momme are lovely in a scarf and thin in a nursery. LS Silk cot sleeves are 22 momme, dense enough to hold their tension through a great many washes rather than going slack and pilled by winter.

What about sensitive skin, eczema and rashes?

The same friction that wears hair also reddens skin, and it is the cheeks that pay.

A baby who turns their head all night wakes with one side pinker than the other, and that asymmetry is the clue — rubbing follows contact, and contact is one-sided. Drool rash is a different animal, clustering where saliva actually pools around the mouth and in the neck folds, and it peaks alongside teething. Eczema is different again: dry rather than damp, genuinely itchy, and inclined to appear in the creases of elbows and knees as well as on the face. Cradle cap has nothing to do with bedding whatsoever — greasy yellow scale on the scalp, harmless, and gone by the first birthday in most cases.

Where a smoother surface helps is narrow but real. It reduces mechanical irritation, and unlike cotton it does not spend the night quietly wicking the barrier cream you applied at bathtime off your baby’s skin.

What it is not is a treatment. Silk will not clear eczema, resolve cradle cap or settle an infection, and a brand that implies otherwise is one to be wary of. If your baby has a diagnosed skin condition, the plan from your GP or dermatologist is the thing doing the work.

Is it safe to put silk in a cot?

This is the question that matters more than every other question here combined, and the answer turns entirely on fit.

Loose bedding of any fibre — silk scarves, soft pillows, blankets, bumpers, sheepskins, soft toys — does not belong in a cot. These are established SIDS risks and no benefit to hair or skin comes close to outweighing them. That is not a caveat; it is the whole frame.

A fitted cot sleeve is a different object entirely. It is engineered to sit drum-tight and flat against the mattress so that the surface beneath your baby stays exactly as firm as it was before. You are not adding softness to the cot. You are changing the texture of something that was already there.

The test is simple and worth doing every single time. Slide a hand beneath it: there should be no give. Tug it with both hands: it should not lift, bunch or travel. Re-check after every wash, because fabric relaxes and Velcro tires. If it will not sit tight on your mattress, do not use it.

One thing we will say plainly, because the category is full of brands that don’t. Red Nose Australia does not endorse, certify or approve individual products, ours included. What we can tell you is how the sleeve is built to fit. For everything else in the sleep environment, the authority is Red Nose’s safe sleeping guidelines, and they are worth reading in full.

What else actually helps?

Supervised tummy time, more than anything sold in a nursery shop. Every waking minute spent off the back of the head is a minute of pressure and rubbing that never happens, and it builds the neck strength that will eventually let your baby turn away from the mattress under their own steam.

After that: keep the room cool and moving, because a dry scalp snags far less than a damp one. Resist brushing matted hair while it is dry — a drop of baby-safe oil to separate the strands first will save you a small handful of them. And skip anything worn on the head for sleep. Hats and headbands are a genuine safety risk and solve nothing.

Then, mostly, wait. It is unsatisfying advice and it is usually the correct advice.

When should you see a doctor?

Most baby hair loss never needs a medical opinion. Some does. Book an appointment with your GP or maternal child health nurse if you notice any of the following:

• Patchy loss with a red, flaking, scaly or inflamed scalp
• Hair loss continuing past six months, or beginning once your baby is sitting up
• Clearly defined circular patches, or broken hairs of obviously differing lengths
• Skin that is weeping, crusted, spreading or plainly sore
• Hair loss alongside poor feeding, poor weight gain or general unwellness

These are uncommon. They are also the reason this list exists rather than a reassuring paragraph — worth ruling out properly rather than assuming the bedding is responsible.

Frequently asked questions

Is it normal for my baby to lose hair at three months?
Yes. Newborn hair loss peaks around three months, driven by the drop in hormone levels after birth. It is temporary and resolves without intervention.

Will my baby’s bald spot grow back?
In the large majority of cases, yes — usually as your baby begins spending less time on their back and the hormonal shed completes. Reducing friction protects the new growth while it comes through.

Can a silk cot sleeve stop baby hair loss?
No. Nothing stops the hormonal shed. A cot sleeve reduces friction, which is a separate and controllable contributor to breakage at the back of the head.

Is a silk cot sleeve safe for a newborn?
It is safe when it fits drum-tight and flat, so the sleep surface stays firm. Loose silk, or any loose bedding, is not. Check the fit before every use and follow the current Red Nose safe sleeping guidelines.

Does silk help baby eczema?
Not as a treatment. It reduces friction and does not absorb barrier creams the way cotton does, which can support skin that is being mechanically irritated. Eczema itself needs a management plan from your GP or dermatologist.

What momme silk is best for a cot sleeve?
Heavier weights hold up better to constant tension and frequent washing. LS Silk cot sleeves are 22 momme for that reason.

Should I stop putting my baby on their back to sleep?
No, never. Back sleeping is the safest position and should not be changed to protect hair. Change the surface, not the position.

The patch will fill in. It nearly always does, quietly and without ceremony, somewhere around the time your baby learns to sit up and stops offering the back of their head to the mattress for twelve hours a day. Until then the only thing genuinely within reach is what they are lying on — and there is a certain comfort in having one small thing to do while biology takes its course.
