I have recently gotten a number of questions about barrettes for thicker hair.  In my personal exprience, a slightly larger barrette back will hold more hair.  With either of these two barrettes, I can put my braided pony tail, folded twice, up on the back of my head.  They hold it with no problems and with stand a lot of movement.maple.jpg

The barrette on the left is on a 3 1/2 inch barrette back, so it is a little longer then the barrettes that you find in the local store.  The barrette on the right has a wider space between the back of the barrette and the piece that holds the hair in the barrette.
