Q: Are scrunchies better for your hair than hair ties?
A: Generally yes. The fabric covering spreads the tension over a wider area and has no metal join to catch, which is what causes snagging with a plain elastic.
Q: Do scrunchies leave a dent in your hair?
A: Far less than a thin elastic, because the hold is spread rather than concentrated in one narrow band. Tying it loosely rather than doubling it over helps further.
Q: Can you wash scrunchies?
A: Yes. Wash them on a normal cycle, ideally inside a mesh bag so they keep their shape, and let them air dry rather than tumbling.
