Hair barrettes for thick hair are often found to be clips slightly larger in length with a locking mechanism that allows for voluminous hair to be easily cinched. We found the best barrettes for thick hair often have a length of at least 2.5" and either auto clasp, snap clip, or stay tight locking mechanisms. These allow thick hair to be brought together, pulled back, and the barrette locked into place without sacrificing comfortability for style.
