The most common reason a claw clip "doesn't work" isn't the clip — it's the size. Korean stylists use a simple rule: match the clip to the amount of hair it needs to hold, not to your total hair.
The quick chart
Fine or short hair (above shoulders): Small claws for full updos, mini claws for half-ups. A big claw will slide right out of fine hair.
Â
Â
Medium hair (shoulder to mid-back): Medium claws for the classic twist updo, small for half-ups.
Â
Â
Thick or long hair: Big claws with double teeth for full updos — the double-teeth grip matters more than size itself. Medium for half-ups.

The half-up rule
Whatever your hair type, go one size down for half-up styles. You're only holding a third of your hair, and an oversized clip looks (and feels) unbalanced.
Three signs you're wearing the wrong size
It slides down within an hour — too big for the amount of hair.
The teeth won't fully close — too small; forcing it will snap the spring.
You get a headache — right size, wrong placement: clip the twist, not the scalp.
