As Mad Men's seventh series draws to a close, there's one niggling question that really needs to be answered: what has Megan Draper's schizophrenic hair been all about?
It's not that she's looked awful - her brunette locks are never anything but groomed, glossy and gorgeous. It's more the issue of her constantly changing hairstyles. One moment, her tresses are long. The next, she's cuddling up to Don with a super sleek crop. Honestly, it's a continuity nightmare.
In fact, Draper's hair changed not once but three times in recent episode, "The Strategy", and it's the varying length that has really perplexed me.
But this only leads to more probing. Were wigs are involved? Also, who on earth has time to style their hair differently three times in a day? Megan found the time to fly from New York to Los Angeles in-between her hectic hair schedule too. Don't get me wrong - I can suspend disbelief for good television, but this pushes the realms of fantasy just a tad too far.
It will remain a secret of the last-ever series - the great mystery of Megan's hair. If you can solve it, tweet us @MyDailyUK.
