How does this sleep cap protect my hair overnight?

The silk lining reduces friction between your hair and the fabric, preserving hairstyles, reducing frizz, and minimizing tangles. By keeping moisture in the hair shaft, it helps maintain smoother strands and fewer split ends over time.

• Mulberry silk interior provides a low-friction barrier for hair.
• Retains natural oils and reduces overnight dryness.
• Prevents rubbing against coarse pillowcases that cause breakage.
• Suitable for delicate styles like curls, braids, and straight hair.

Will this bonnet stay on through the night?

The LULUSILK cap uses an upgraded adjustable strap paired with a secure elastic band so the bonnet fits snugly without slipping. The design balances hold and comfort so it stays in place for a full night’s sleep, whether you change positions or use a CPAP mask.

• Adjustable strap customizes fit for most head sizes.
• Elastic band provides gentle but secure hold.
• Lightweight construction avoids pressure points around ears.
• Works well with active sleepers and CPAP gear.

Is this cap comfortable and breathable for all seasons?

• Featherweight feel minimizes awareness during sleep.
• Modal outer layer adds softness and airflow.
• Silk interior prevents sweaty friction points.
• Designed for use in summer and winter alike.

What hair types and occasions is this bonnet best for?
