Locs have specific overnight protection needs that most bonnets aren't designed for. Volume, length, and the weight of mature locs all affect what works — and what doesn't. Here's everything you need to know about choosing the right silk bonnet for locs.
Why Locs Need Overnight Protection
- Friction frizz — cotton pillowcases create friction that roughens the outer surface of locs, causing frizz and lint buildup over time
- Moisture loss — cotton absorbs the natural oils and any loc butter or oil you've applied, leaving locs dry and brittle
- Compression and reshaping — sleeping without protection can flatten or reshape locs, especially younger or thinner ones
- Lint transfer — cotton fibers shed and embed in locs, which is notoriously difficult to remove
A silk bonnet eliminates all four problems in one step. For a full overview of silk bonnets including sizing, care, and who needs one: Silk Sleep Bonnets: Everything You Need to Know.
The Most Important Factor: Size
This is where most people go wrong with locs. Standard bonnets are designed for loose hair — they don't account for the volume and weight of a full head of locs. A bonnet that's too small compresses your locs, defeats the purpose of protection, and is uncomfortable enough that you'll take it off in your sleep.
For locs, always size up. The Soreia Organic Silk Sleep Bonnet comes in two sizes:
- Regular (53–66 cm) — suitable for shorter locs (under 6 inches), thin locs, or a smaller head circumference
- Large (55–68 cm) — recommended for most loc wearers. Accommodates medium to long locs, thick locs, high-volume styles, and pineappled locs. When in doubt, choose Large.
To measure: use a soft tape measure around the widest part of your head (just above your ears and across your forehead). If your measurement is near the top of the Regular range, choose Large.
Why Silk Outperforms Satin for Locs
- Polyester satin generates static, which increases frizz on loc surfaces
- Polyester traps heat against the scalp, which can affect loc health over time
- Polyester sheds microfibers that can embed in locs
- Silk is a natural protein fiber — static-resistant, breathable, and fiber-shedding is minimal
For locs, 100% mulberry silk is the only material that addresses all four overnight damage factors. And not all silk is equal — 22 momme Grade 6A is the specification that delivers the smoothest surface and the most durable protection.

How to Wear a Silk Bonnet with Locs
- Gather your locs loosely — a loose pineapple or simply gathering them to one side works well for most loc lengths
- Use a silk scrunchie if needed — for longer locs, loosely secure them before the bonnet goes on. Never use a regular elastic — it creates tension and breakage at the point of contact
- Slide the bonnet on from front to back — make sure all locs are inside and the elastic sits at your hairline, not on your locs
- Check the fit — the bonnet should feel secure but not tight. You should be able to fit two fingers under the elastic band
The Lint Problem: Silk vs Cotton
Lint in locs is one of the most frustrating loc maintenance issues — and it's almost entirely caused by sleeping on cotton. Cotton fibers shed constantly and embed in the loc structure, where they're nearly impossible to remove without retwisting. Silk does not shed fibers in the same way. Switching to a silk bonnet — and a silk pillowcase as a backup layer — is the most effective way to prevent lint accumulation in locs.

Frequently Asked Questions
What size bonnet do I need for long locs?
For locs past shoulder length, choose Large. Long locs have significant volume even when gathered, and a Regular bonnet will compress them. The Soreia Large bonnet (55–68 cm) accommodates most long loc styles including pineapples and gathered bundles.
Can I sleep with locs without a bonnet?
You can, but you'll experience more frizz, lint, and moisture loss over time. At minimum, sleep on a silk pillowcase. For full protection, a silk bonnet is the most effective solution.
How do I keep my bonnet on while sleeping?
Choose a bonnet with an adjustable elastic band that sits securely at your hairline. If your bonnet slips off, it's usually a sign the size is too small — try sizing up.
Is silk or satin better for locs?
Genuine mulberry silk is better for locs than polyester satin. Silk is static-resistant, breathable, and doesn't shed microfibers into your locs. Most products sold as "satin" are polyester — check the fiber content before buying.
