A scrunchie wraps the elastic in fabric, so it holds hair more gently than a bare hair tie. Silk and satin slide, which means less of a dent in the morning.
Mulberry silk scrunchie
The softest hold. Good for sleeping and for fine hair.
Look for
"100% mulberry silk", ideally with a momme number (19 to 22 is common).
Elastic that is fully covered, with no rubber showing.
The size that suits your hair: skinny, regular or oversized.
Skip it if you lose hair ties often. A satin multipack costs less to replace.
Rough estimate, not checked RM10 to RM40 each, sometimes sold in sets
