Not even Sherlock Holmes could work that one out! Jude Law sports MUCH fuller head of hair at Toronto International Film Festival

Just a mere matter of months ago he was sporting a fairly dramatic bald patch as he walked the red carpet to promote the second film in the Sherlock Holmes franchise.
But not even the legendary fictional detective could solve the mystery that is Jude Law's hair.
Stepping out last week at the Toronto International Film Festival, the 39-year-old actor was showcasing a seemingly much thicker head of hair than in previous months.

Promoting new movie Anna Karenina, the father-of-three proudly displayed a fine set of curls as he walked the red carpet.
Ignoring the apparent mystery surrounding his hair, the Alfie star looked every inch the dapper gentleman in his impeccably tailored three-piece suit and skinny black tie.
And it would seem Law was keen to make the most of his luscious locks by adding a spot of facial fur to his look.

The London-based actor stars alongside Keira Knightley in Anna Karenina, playing the titular character's husband, Alexei Karenin, in the adaptation of Leo Tolstoy's 1877 novel.
Despite making his name thanks to his smouldering good looks, Law was almost unrecognisable in the new movie.
However, he admitted he was made to look ugly and balding in order to play Karenina's sombre and humourless spouse.

And he explained his new look didn't go down too well with his three children with ex-wife Sadie Frost; Rafferty, 15, Iris, 11, and Rudy, 10.
Speaking at the London premiere of the movie, he said: 'I didn't look quite the same as I do on set, off set, but my haircut didn't go down very well with my children.
'I think that's why I wore a hat for the best part of three months.'
