The unexpected Seventies-inspired trend that celebrities are signing up for: the lob. This is one length collarbone-skimming 'long bob' can be caught on everyone from Fearne Cotton to singer Jessie J, actress Jessica Alba, Jennifer Aniston, Kate Bosworth and Scarlett Johansson.

Now the trend is taking off and women across London can't wait to lob it off! "It's going to be the big hairstyle this season," confirms Jason Cocking director of Lisa Shepherd London. "on average, we are doing around 20 a week but recently we did more than 30."

"Like the original, sharp Sassoon looks, this is low maintenance, the clean line of the cut means it grows out nicely without losing its shape. You'll easily be able to leave 12 weeks between appointments."
