Silk Bonnet

Most adults fit our Standard bonnet (head circumference 21–23 in / 53–58 cm), which seats snug at the hairline without leaving a forehead crease. If you wear locs, braids, twists, a silk press, or a high pineapple, size up to the Oversized / Jumbo bonnet (24–28 in / 61–71 cm) so the elastic doesn't compress the roots. Children and petite adults can opt for the Junior fit. All Muriersilk bonnets have a covered elastic band so the seam never touches your edges.

Yes — and there is real friction science behind it. Cotton and polyester satin pillowcases have a coefficient of friction roughly 2 to 3 times higher than 22-momme mulberry silk, which is what causes the late-night breakage, single-strand knots, and morning frizz halo. Sealing your hair inside a silk bonnet keeps the cuticle flat, locks in the leave-in conditioner you applied at night, and dramatically reduces split ends over a 30-day cycle. Our customer reviews back this up across 4C, wavy, and chemically relaxed hair types.

Cotton is hydrophilic, meaning it actively pulls moisture and oils out of your strands overnight; that's why curly hair often wakes up dry and brittle on a cotton pillowcase. Silk is naturally smooth, temperature-regulating, and barely absorbent — your natural sebum and any leave-in product stay where they belong. Mulberry silk is also hypoallergenic, so it won't aggravate scalp eczema or acne-prone foreheads the way cotton bedding can.

Hand-wash gently in cool water (below 30°C / 86°F) with a pH-neutral silk wash or baby shampoo every 1 to 2 weeks. Do not wring — press out water between two towels and lay flat to air-dry away from direct sunlight. Skip the dryer, bleach, fabric softener, and any product that contains alpha-hydroxy acid or benzoyl peroxide; they will yellow the fibers. A well-cared-for Muriersilk bonnet lasts 12 to 18 months of nightly use. Full step-by-step in the <a href="/guides/silk-care">Silk Care Guide</a>.

Yes, nightly wear is where a silk bonnet earns its place. The friction damage from cotton pillowcases is cumulative &mdash; one night doesn't ruin your wash day, but 30 nights of single-strand knots, mid-shaft splits, and lost moisture absolutely do. Wearing a 22-momme mulberry silk bonnet every night locks in your leave-in conditioner, keeps the cuticle flat, and preserves curl pattern and length retention over a 60- to 90-day cycle. The exception is if you do a deep treatment that needs to breathe; otherwise, slip it on, and let the silk do its job in the background.

Yes, when you pick the right cut and size. Our reversible double-layer bonnets seat snug because the second layer adds tension at the band, and our adjustable-elastic and long-tie styles let you dial in fit without a forehead crease. If you're a heavy mover or you have a high pineapple, a back-tie or long-tie silk bonnet is the right pick &mdash; the tie gives you mechanical hold without elastic compression. People who report bonnets sliding off usually have a too-loose elastic or a wig-style bonnet sized for braids on loose hair. Size down or pick a reversible style.

Damp, yes &mdash; soaking wet, no. A silk bonnet over fully wet hair traps moisture against the scalp and can encourage mildew, scalp itch, and a longer drying cycle. The best practice is to towel-dry, apply your leave-in, let the hair air-dry to roughly 70 to 80 percent, and then slip the bonnet on. The silk wicks just enough to finish the drying overnight without flattening the curl. We cover this in detail in our <a href="/blog/can-you-put-a-silk-bonnet-on-wet-hair">complete wet-hair-bonnet guide</a>, including which Muriersilk styles handle damp hair best.

Most adults fit our Standard cut, which is sized for a 21 to 23 inch (53 to 58 cm) head circumference and seats snug without leaving a forehead mark. If you wear locs, box braids, twists, a silk press, or sleep with a high pineapple, size up to our Oversized or Long-Tie style (24 to 28 inches / 61 to 71 cm) so the elastic doesn't compress the roots. Children and petite adults can opt for a Junior fit. Every Muriersilk bonnet has a covered elastic band, so the seam never touches your edges directly &mdash; this is the detail that ends the elastic-mark complaint.

Every 1 to 2 weeks for nightly wear is the right rhythm, more often if you use heavy oils. Hand-wash in cool water (below 30 degrees Celsius / 86 degrees Fahrenheit) with a pH-neutral silk wash or a gentle baby shampoo. Do not wring &mdash; press water out between two towels and lay flat to air-dry away from direct sun. Skip the dryer, bleach, fabric softener, and any product containing alpha-hydroxy acids or benzoyl peroxide, which yellow silk fibers.

Yes, and arguably better than for any other hair type. Fine, thinning, and chemically-relaxed hair has a weaker cuticle and breaks under friction that thicker hair shrugs off. A 22-momme mulberry silk bonnet eliminates that friction entirely, preserves the cuticle alignment that gives fine hair its shine, and stops the morning frizz halo that cotton pillowcases create. Our covered-elastic and long-tie styles are the right pick here &mdash; they hold without pulling at the hairline, which matters for traction-sensitive hair. Pair with a lightweight leave-in for the best 30-day result.
