First of all, there was Hermione Granger, who made it OK to have long, frizzy hair. I was able to embrace my unruly locks in the knowledge that Hermione made it cool. However, shortly after filming the last Harry Potter film, Emma Watson cut all her hair off.
Then there was Amy Pond, on Doctor Who, who had lovely, long, ginger hair. Finally, someone in the public eye who had naturally ginger hair and wore it well. Then Karen Gillan shaved her head.
Last year, when watching The Voice with friends, we saw that Jessie J had her hair in a herringbone (or fishtail) plait (a style which was also seen on other celebrities at the time). I'd always wanted to do my hair like that but didn't know how. So one of the girls showed me and the group of us spent the rest of the evening plaiting each other's hair. But Jessie J shaved her head for Comic Relief. We weren't copying her hair style when we watched the final of The Voice!
The Hunger Games books became hugely famous with the release of the first two films. The main character, teenager Katniss Everdeen, is famous for her plaits. In the first book, her stylist is impressed by the plait her mother has done for the Reaping, and copies it when he styles her. Later on, her mother shows the rest of the prep team how to do the plaits. In the films, Katniss's sister Prim also has intricate plaits around her head. I'm not concerned by the fact that Jennifer Lawrence has gone back to her natural colour - in fact, I encourage that. What does concern me, though, is that she, too, has cut all her hair off and gone really short.
So, all these wonderful women who made it cool to have long, thick, plaited, ginger hair have now either cut their hair short or shaved their heads. I hope that this trend doesn't continue and that it doesn't become the norm to have ridiculously short hair or none at all.
