Why cotton is hard on curly and wavy hair

Curly and wavy hair has a naturally open cuticle structure. This makes it more porous than straight hair, meaning it absorbs and loses moisture faster.

Cotton is absorbent. When you sleep on a cotton pillowcase, it pulls moisture from your hair through the night. By morning, your curls or waves are dry, frizzy, and disrupted. Cotton also has friction. Curly hair catches on the rough cotton surface every time you move, stretching the curl pattern and causing breakage.

What silk does for curly and wavy hair

Many curly hair communities use a silk pillowcase as an alternative to a silk scarf or bonnet. It protects the curl pattern overnight without having to wear anything on your head while you sleep.

Is it better than a silk bonnet or scarf?

A silk bonnet or scarf gives more complete protection because it wraps all of your hair. A silk pillowcase covers only the hair that touches the pillow.

For many people, wearing a bonnet or scarf is uncomfortable or falls off during the night. A silk pillowcase is a simpler alternative that requires no change to your routine. If you have very thick curly hair, using both a silk pillowcase and a loose silk scarf is the most protective option.

What to look for for curly hair specifically

• 6A grade mulberry silk: The higher grade means a more uniform, smoother surface with fewer joins where curly hair can catch.
• 25 momme weight: Heavier silk holds its smooth surface longer through washing. Curly hair routines involve regular product use, so you will wash your pillowcase often.
• Hidden YKK zipper: No exposed hardware to snag on your curls.

Does it work for all curl types?

Yes. The benefits apply across all curl and wave types, from loose beach waves to tight coils. People with tighter curl patterns and more porous hair tend to notice the difference more quickly.
