How to Put Your Hair in a Silk Bonnet (It Differs by Hair Type)
Quick answer: How you put your hair into a silk bonnet matters as much as owning one. Straight or fine hair should be detangled and loosely twisted before going in. Curly and textured hair should not be brushed at all — tuck the curls in gently to preserve their shape. Long hair needs enough room to sit without folding hard against itself. Get the technique wrong and you can create the dents and tangles you bought the bonnet to avoid.
Owning the bonnet is the easy part. Getting your hair into it properly is where the result actually comes from.
Most disappointing bonnet experiences are technique problems rather than product problems. Hair gets shoved in, folds against itself under tension, and comes out in the morning with a crease where there was meant to be a wave. Or it is brushed smooth first, which is precisely wrong for curls. Or the bonnet is too tight, and there is a dent at the hairline by 7am.
None of that is the silk failing. It is worth five minutes to get right.
How should you prepare hair before putting it in a bonnet?
Fine or straight hair
Detangle gently first — a wide-tooth comb, working from the ends upward rather than dragging from the roots. Then gather the length into a loose twist and coil it softly on top of the head before the bonnet goes on.
The twist matters. Loose hair inside a bonnet migrates and tangles as you move; a light twist keeps it organised without putting the strands under tension. Do not secure it tightly, and do not use an elastic — if you need something, a silk scrunchie is the gentlest option.
Curly or textured hair
Do not brush. This is the one instruction that reverses completely between hair types, and brushing dry curls before bed undoes the curl pattern you are trying to protect.
Instead, gather the curls loosely and tuck them into the bonnet by hand, letting them sit in their natural clumps. The pineapple method — gathering hair loosely at the crown before covering — works well under a bonnet for looser curl patterns. Tighter textures often do better with the hair simply tucked as it falls.
Long or thick hair
The main risk is volume. Hair crammed into a bonnet that is too small folds hard against itself, and a hard fold under eight hours of pressure becomes a crease.
Coil the length loosely and check there is room to spare before you settle. If there is not, you want a larger size or an adjustable silk hair wrap rather than a fixed bonnet. Our head measuring guide takes two minutes.
Should you apply products before a bonnet?
If you use leave-ins, oils or curl cream, night is a good time for them — and a bonnet is a good reason to bother. Cotton is absorbent by design, so on a standard pillowcase a meaningful share of what you applied ends up in the bedding rather than on your hair. Silk absorbs a fraction as much, so the product is still working in the morning.
Apply to damp rather than soaking hair, and give it a few minutes before covering. Sealing genuinely wet hair under fabric all night is not comfortable and does the scalp no favours.
How tight should a silk bonnet be?
Snug enough that it is still on at 3am. Loose enough that it leaves no mark.
If you wake with a line across your forehead or an indent at the hairline, the band is too tight — and tension at the hairline is exactly where fragile hair breaks. A bonnet should hold position through its shape and fit, not through compression.
What about humid nights?
Humidity is the reason many Australians reach for a bonnet in the first place, and it does help — a smoother surface means the cuticle takes less mechanical abuse overnight, so hair starts the day calmer.
What it will not do is seal your hair against the atmosphere. Once you are outside in Brisbane in February, the air has access to your hair regardless of what it slept in. Silk gives you a better starting point, not immunity.
One practical note for warm nights: real mulberry silk breathes, but polyester satin does not. If your bonnet leaves you with a sweaty scalp, check what it is actually made of — the difference is covered in silk bonnets vs satin bonnets.
How do you know it is working?
Give it a fortnight and judge on mornings, not miracles. Less tangling on waking, fewer flyaways, a blowout that survives to Day 2, curls that need less reviving. Those are the wins available.
If nothing changes at all, the usual culprits are fit, technique or the bonnet coming off in the night — in that order.
Frequently asked questions
How do you put long hair in a silk bonnet?
Coil the length loosely and place it on top of the head before the bonnet goes on, leaving room to spare. Hair crammed in tightly folds against itself and creases under overnight pressure.
Should you brush your hair before wearing a bonnet?
Only if it is straight or fine — detangle gently with a wide-tooth comb. Do not brush curly or textured hair, as it disrupts the curl pattern you are protecting.
Can you use a silk bonnet on wet hair?
Damp is fine; soaking is not. Wet hair sealed under fabric all night is uncomfortable and unhelpful for the scalp. Let it dry to damp first.
How tight should a silk bonnet be?
Snug enough to stay on overnight, loose enough to leave no mark. A line across the forehead or an indent at the hairline means it is too tight, and hairline tension is where fragile hair breaks.
Do you apply hair products before putting on a bonnet?
Yes, if you use them. Silk absorbs far less than cotton, so leave-ins and oils stay on the hair rather than transferring into the bedding.
My bonnet keeps falling off overnight — what am I doing wrong?
Usually fit. A bonnet that is too large will not stay put, and one that is too tight gets pulled off in discomfort. Measure properly, or choose an adjustable wrap.
Our mulberry silk bonnets are OEKO-TEX® Standard 100 certified, and come in sizes that account for the fact that hair is not one size.

A bonnet is not a complicated object, which is exactly why people assume there is nothing to get wrong. Five minutes of technique is the difference between waking up with the hair you went to bed with and waking up with a crease you will spend twenty minutes undoing.
