I have an asymmetrical undercut bob. Not a full speak to the manager, but there are days... 
Anyway, I'm trying to wash it less. It's long enough to tie back but not really long enough to style as tied back. A friend suggested a messy bun scrunchie and to tie it back as a low bun, and I've looked and the styling seems... a little far from mine! I wear sort of, Joseph/All Saints/Toast sort of stuff, biker jackets and skinnies etc, and I'm around 40. I don't have a plastic surgery face.
So can anyone tell me from personal experience - are these awful or genius? www.lullabellz.com/large-premium-messy-bun-style-hair-scrunchie-hair-extensions or any recommendations for other (better?) versions?
