By our founder
I see it all the time: people who care deeply about their hair, who invest in good cuts, treatments and products, quietly leaving one step out of their routine. They've been told the only way to do it properly is with 100% silk.
Spend five minutes in the online haircare world and you'll be told that silk is the only acceptable choice. Natural fibre or nothing. Anything less is a waste of money, or worse, a sign you don't really care.
I run a business that sells silk. I also sell satin. And I refuse to tell my customers that silk is the only option, because it isn't true, and because that message is quietly pushing people out of a habit that would genuinely help them.
A debate that gatekeeps
The silk-versus-satin argument has turned a simple act of self-care into a purity test. And like most purity tests, it mostly serves the people who can already afford to pass it.
Silk is a natural protein fibre. It's breathable and beautiful, and it costs more to produce, so it costs more to buy. Satin isn't a fibre at all. It's a weave, a smooth, glossy finish usually made from synthetic yarn, and it costs far less. These are real differences, and anyone who values natural fibre has every reason to choose silk.
Weighing it up
- Silk: a natural protein fibre. Breathable and soft. A higher investment, for those who love natural fibre.
- Satin: a weave, not a fibre: smooth and glossy. Easy-care, and an everyday price that makes the habit easy to keep.
- What they share: a smooth surface, and far less friction than cotton.
But when the conversation becomes "silk or don't bother," a lot of people quietly choose not to bother. They keep sleeping on cotton. And that is the outcome I care about.
What I keep noticing is who gets left out. It isn't people who don't care about their hair. Many of them already put a lot into it. They just can't justify the price of 100% silk on top of everything else. Or no one has explained its benefits in a way that makes it worth it to them. Neither of those is a failing. Neither should mean missing out on protecting your hair while you sleep.
What silk really does, and what it doesn't
I love silk, and I want to be honest about why it's worth it for some people. Its surface is so smooth that hair slides rather than snags. That can mean less breakage, less frizz and fewer creases by morning. Silk is also less absorbent than cotton, so it's less likely to soak up your hair's natural oils, or the serum you put on before bed.
It breathes, too. That helps you sleep cooler in summer and cosier in winter. And as a natural fibre, many people with sensitive skin find it gentler to sleep on.
But I won't oversell it. Silk isn't a medical treatment. It won't clear acne, erase deep wrinkles or heal eczema on its own, and anyone promising that is selling a story.
Here's the honest comparison. Much of what makes silk good for your hair comes from how smooth it is, and a satin weave is smooth too. Satin gives you that same low-friction glide and absorbs far less than cotton, at a much lower price. What it can't match is silk's breathability and natural temperature control. For some people that difference is worth paying for. It just isn't a reason to skip the step altogether.
The step nobody talks about
We spend about a third of our lives asleep, and our hair is there for every minute of it. Each time you turn over, it rubs against whatever is under your head. On a rougher surface like cotton, that friction roughs up the hair's outer layer. You wake up to frizz, tangles, creases and a blowout that has lost its bounce.
People spend real money on haircuts, treatments, serums and heat protection, then undo a share of that work overnight without noticing. Sleep is the silent, forgotten step in a haircare routine.
Here's what the debate tends to skip: silk and satin share the property that matters most. Both give your hair a smooth surface to glide over. Either one is a meaningful step up from cotton.
The biggest gain isn't silk over satin. It's anything smooth over nothing.
Why we make both
So at Sunday Morning, we make both. Our silk is for people who love natural fibre and want to invest in it. Our satin is for people who want an everyday routine that's easy to keep up and easy on the budget.
We deliberately designed both ranges in similar colourways. I didn't want satin customers getting the leftover shades, or feeling they'd bought the lesser version. The ritual should feel the same whichever fabric you choose: the soft pillowcase, the scrunchie instead of a tight elastic, the small moment of looking after yourself before bed.
Self-care shouldn't have a price of entry
I'd rather a customer walk away with a satin set they'll use every night than a silk one they felt pressured into and couldn't justify. Good habits come from making the habit easy to start, not from making people feel they've failed before they begin.
So if you've ever wondered whether satin is good enough, my answer is simple. Yes. Silk is lovely if it's right for you. But the real mistake isn't choosing the wrong fabric. It's skipping the step altogether.
Finish your routine. Bedhead doesn't have to be bad!
