Silk Pillowcase vs Silk Bonnet: Which is Better for Hair?

Written by Anya, Founder of The Silk Collection · Updated August 2026

A silk pillowcase and a silk hair wrap do different jobs. The pillowcase protects everything that touches it, hair and skin alike, every night without you thinking about it. The wrap holds the hair itself, keeping styles, curls and moisture in place. They work at their best together, and if you are choosing one, choose by the job.

If you are looking to improve your daily haircare routine with the aim of getting healthier hair, it can be overwhelming when faced with the different options of hair oils, hair masks, leave-in treatments and even specific hair brushes to promote healthier hair.

A commonly overlooked but highly effective method of haircare is incorporating silk into your overnight haircare, as this offers the opportunity to nurture and protect your hair for hours while you sleep.

For those looking to incorporate overnight haircare into their daily haircare routine, a silk pillowcase and a silk hair wrap are two easy ways to effortlessly protect your hair as you sleep overnight. This has led to many of you to ask - do you need both?

"Which is better for haircare - a silk pillowcase or silk bonnet? Do I need both?"

Here we go through the benefits of using both a silk pillowcase and a silk hair wrap, and in which situations you may prefer using one over the other. We'll also include some of our top overnight haircare tips to help keep your hair strong and healthy as you sleep!

Why mulberry silk is the best material for haircare

Before we go into the relative benefits of a silk pillowcase vs. silk bonnet, let’s understand why silk is the fabric of choice for haircare.

Silk, especially mulberry silk, is known for its smooth surface that glides against hair, which makes it a premium material for hair care compared to traditional cotton pillowcases. This means that mulberry silk pillowcases reduces friction against the hair, which helps to:

• Preventing hair breakage
• Reducing split ends
• Minimising frizz

Therefore it is essential that you opt for real silk pillowcases and hair wraps crafted from pure mulberry silk (rather than synthetic alternatives) so that you can experience these haircare benefits. When deciding which silk haircare accessory is best for you, there are a few factors to consider when deciding whether to use one or the other (or both!).

Silk pillowcase for overnight haircare

Silk pillowcases are not just a luxury addition to your bedding; they are a night-long hair treatment. As you toss and turn, a silk pillowcase allows your hair to glide smoothly, minimising knots, tangles, and breakage. This is especially beneficial for those with long hair or hair prone to tangling. This makes a silk pillowcase the best choice of pillowcase for the ultimate hair care compared to a traditional cotton pillowcase.

Why use a Silk Pillowcase over a Silk Hair Wrap?

1. If you don't like to wear headwear as you sleep: Not everyone likes to wear a cap to sleep each night. Silk pillowcases are ideal for providing all the benefits of silk for haircare, without you needing to wear anything on your head at night.

2. if you want combined skincare and haircare: A big benefit of using a silk pillowcase is that the smooth texture also has a number of benefits for skin as well as for hair. Silk pillowcases are particularly beneficial for those with sensitive skin, as the hypoallergenic properties of silk can also soothe the skin, reducing the chances of acne and irritation.

3. If you want to elevate your bedroom decor: Silk pillowcases also add a touch of luxury to your bedroom beyond their practical benefits for hair and skin.

Best Time to Use

Every night! Making a silk pillowcase part of your daily sleep routine can transform the health and appearance of your hair and skin over time. We spend around a third of our lives sleeping with our face and hair pressed against our pillow, so it is worth investing in a 100% silk pillowcase for overnight haircare and skincare!

Tips for Maximising Benefits:

• Make sure it is a real silk bonnet you are using! Find out more about the benefits of using a real silk bonnet here.
• Opt for a high momme silk (the measure of silk’s weight and quality) for durability and enhanced hair protection as you sleep.
• Make sure it is a real silk pillowcase - before purchasing, make sure to check the label to see if it is 100% silk so that you can get all the benefits from real silk.
• Combine with a silk hair wrap (find out more below!) for double protection if you have very fragile or damaged hair.

Here is what that looks like on real hair, word for word from a verified review.

★★★★★

“I've really noticed a difference since I started sleeping on my new silk pillowcases. My hair is less flyaway and my face is less creased when I wake up in the morning. They feel lovely and cool against my cheek which helps me get back to sleep. Very impressed!”

Silk Hair Wrap for Dedicated Overnight Haircare

Whilst a silk pillowcase for hair has all-round benefits, silk hair wraps offer a more targeted approach to overnight hair protection. Using a hair wrap made from silk helps to maintain hairstyles, moisture, and hair health, particularly for curly, textured, or chemically treated hair that requires extra care.

Why use a Silk Hair Wrap rather than a Silk Pillowcase?

1. Ideal for those looking to maintain hairstyles: If you are looking specifically for a tool to protect your hair and prolong hairstyles, then a Silk Hair Wrap is the best tool to use. A hair wrap can maintain the longevity of certain hairstyles, such as braids, curls, and blowouts, by protecting the hair from frizz, tangling, and flattening. This is especially useful for those who want to extend the life of their hairstyles, reducing the need for frequent styling or touch-ups.

2. Those with curly, textured, or long hair will find a silk bonnet useful for keeping their hair tangle-free and moisturised and contained overnight. This is particularly important for those with curly hair as this hair type is more prone to dryness. Find out why a Silk Bonnet for Curly Hair is an essential hair care tool here!

3. Good for travel - If you're going on holiday, a hair wrap is easy to pack and use anywhere, making it a convenient option for maintaining a haircare routine while traveling to ensure that your hair remains protected no matter where you are sleeping.

4. Budget-friendly option - if you are looking to start your silk haircare journey and have budget in mind, investing in a silk pillowcase pair will be a bigger investment. Starting with a Silk Hair Wrap can be a good way to enjoy the benefits of silk for hair at a lower cost.

Best Time to Use:

Every night, especially after applying leave-in treatments or oils, to lock in moisture and prevent hair products from transferring to your pillow and face.

“The silk hair wrap kept my naturally curly hair in tact and as I’ve continued to use it, the overall health of my hair has improved - glossier and significantly less restyling time. It’s comfortable to sleep in and still looks quite stylish. I need to get more colours!”

Silk Pillowcase and Silk Hair Wrap: A Match Made in Haircare Heaven

For the ultimate overnight haircare regime, we highly recommend using both a silk pillowcase and silk hair wrap together to maximise overnight haircare benefits.

This haircare duo is your ticket to waking up with healthier, more radiant hair every morning. Using both a silk pillowcase and a silk bonnet can provide the ultimate protection and nourishment for your hair, ensuring you get the most out of your beauty sleep:

• Maximum Moisture Retention: The silk bonnet keeps your hair treatments and natural oils close to your strands, and just in case strands of hair come out from the wrap as you sleep, the silk pillowcase offers double protection as the second layer underneath.

• Combined skincare and haircare - using both the silk pillowcase and hair wrap together will provide maximum beauty sleep benefits for both hair and skin!

• Enhanced Protection Against Breakage: While the silk pillowcase reduces friction for your hair and skin, the silk bonnet ensures that even the most delicate hairstyles are preserved, preventing tangles and knots.

• Versatility and Convenience: Using both allows you to adapt your nighttime haircare routine based on your current hair needs, providing flexibility and ensuring the best care for your hair in any condition.

This is the same double protection we recommend in our guide to what a silk pillowcase does for frizzy hair: The Silk Hair Bonnet holds your hair and its moisture in place, and the pillowcase protects whatever the bonnet does not catch, while looking after your skin at the same time. One layer for the hair, one for everything else.

Some of our customers arrived at this double layer on their own.

★★★★★

“I’ve been really pleased with my silk hair wrap. It is good quality and really helps with preventing tangling. I use a couple of hair clips to help it stay in place and a silk pillowcase is also helpful to reduce friction between the turban and pillow. Lovely product and excellent service.”

The silk we use, and what it costs

Here at The Silk Collection, we have been crafting pure mulberry silk pillowcases and hair accessories for years, with thousands of you making the switch to silk. Both pieces in this comparison are cut from the same fabric: 22 momme, Grade 6A, 100% mulberry silk, certified to OEKO-TEX Standard 100.

The Pure Silk Pillowcase is £55, or £99 for the set of two. The Silk Hair Bonnet is £45. If you would like both, The Ultimate Silk Hair Care Bundle brings the full overnight routine together for £115. Every order arrives in our signature gift box, with free UK delivery over £60 and 30-day returns.

Our focus is on creating better basics, made from the highest quality silk, to elevate the steps in your routine you are already doing. No extra steps or complications. Just better quality materials.

TOP TIP: one we learned the hard way with our own bonnets: put it on once hair is fully dry, and tuck the lengths in loosely rather than coiled tight. If yours still slips overnight, a loose plait underneath makes all the difference.

Silk Pillowcase vs. Silk Bonnet: Making the Choice

If you are looking to start your silk haircare journey with just one, making the choice between a silk pillowcase and a silk bonnet comes down to personal preference, hair type, and specific haircare needs:

• For combined haircare and skincare: Opt for a silk pillowcase. It’s an easy, effective method to protect your hair and skin simultaneously.

• For maintaining hairstyles and maximising moisture retention: Choose a silk hair wrap to keep hair hydrated, styled, and free from tangles.

Silk pillowcase vs silk hair wrap: which should you choose?

If you only buy one, choose a silk pillowcase for all-round hair and skin protection with nothing to wear, or The Silk Hair Bonnet if your priority is holding styles, curls and moisture in place. For the full effect, our customers wear the bonnet and sleep on the pillowcase together.

More overnight haircare tips

Our top overnight haircare tips

• Loosely tie your hair with a silk scrunchie to prevent tension and breakage. A loose braid or ponytail can help manage hair overnight, especially when combined with silk accessories.

• Avoid going to bed with wet hair to minimise damage and breakage. Wet hair is more delicate and prone to breakage.

• Use Silk Heatless Curlers to style hair rather than heated curling tools. This is an effective way to style your hair without needing any heat. Once the heatless curler is in your hair, simply put the Silk Hair Wrap on top to preserve the style and reduce frizz as you sleep!

Frequently asked questions

Can I use both a silk pillowcase and a silk bonnet together?

Yes, and this is the routine we recommend most often. The Silk Hair Bonnet holds your hair, styles and overnight treatments in place, while the pillowcase protects any strands that escape and looks after your skin at the same time. They cover different jobs, so nothing overlaps or conflicts.

Which should I buy first if budget is tight?

Choose by the job rather than the price, as they are close: The Silk Hair Bonnet is £45 and The Pure Silk Pillowcase is £55. If your priority is protecting curls, styles or overnight treatments, start with the bonnet. If you want hair and skin covered every night with nothing to wear, start with the pillowcase.

Will a silk bonnet stay on all night?

The Silk Hair Bonnet has a soft elasticated band and a generous shape, and most of our customers tell us it stays put until morning. If yours slips, put it on when your hair is fully dry, tuck the lengths in loosely, and try a loose plait underneath. A small hair clip at the edge works well too.

Do I still need a silk pillowcase if I wear a bonnet?

You do not need one, but they protect different things. The bonnet looks after the hair inside it; the pillowcase looks after your skin and any strands that come loose during the night, and it is still working on the nights you skip the bonnet.

Is a silk bonnet suitable for curly and textured hair?

Yes. Curly and textured hair tends to lose moisture and definition against ordinary bedding, and a silk bonnet keeps curls gathered, reduces friction and helps hold overnight treatments where they belong. Many of our customers with curls wear one every night.

Can I wear The Silk Hair Bonnet over heatless curlers?

Yes. Wrap your hair around the curler as usual, then put the bonnet over the top to hold the set in place while you sleep. It is one of the most popular ways our customers use it.

What are they actually made from?

Every piece in this comparison is 22 momme, Grade 6A, 100% mulberry silk, certified to OEKO-TEX Standard 100, which tests textiles for substances harmful to skin. The momme weight matters because it measures the silk's density, which is what gives the fabric its smooth surface and durability.

How do I wash a silk pillowcase or bonnet?

Hand wash in cool water with a gentle detergent, or machine wash at 30 degrees in a mesh bag on a delicate cycle. No fabric softener and no tumble drying; dry flat away from direct heat. Cared for this way, from our own experience 22 momme silk keeps its feel wash after wash.
