It's a bird! It's a plane! Oh wait, that's just your hair. Feather extensions have taken over the streets and it's an interesting approach to new hairstyles. We've seen the weave rise to fame and drop away, we saw the colour panels fade out and now we're flying high with feathers in our hair. They're easy to wear - you just clip them in and go - which might account for their popularity; We've seen them on women everywhere.
