No beauty kit is complete without the humble bobby pin. You can use it to secure sections of hair and hold any style in place.
But did you know you can also use these little pins to keep your hair straight or to perfect the shape of your fringe?
Here we have compiled the definitive list of 20 bobby pin hair hacks and tutorials, from intricate braids to casual updos.
There has been fierce debate about whether the pins should be used with the wavy or straight side on the scalp (here in the stylist.co.uk team we are split 50/50) but however you choose to use them, these hardworking pins are both incredibly useful and extremely versatile.
