Canada's Prime Minister Justin Trudeau hasn't had a haircut since the country went into lockdown, and while we all sit and wait for this to be over, his increasingly shaggy mane is being used by some to track the passage of time.

Almost every day since the lockdown began, Trudeau's movements, both public and private, have been documented, be it at his daily pandemic address, during Parliament, at ceremonies and events, or while spending time with his family.

And each day, his hair grows a little longer.

I watch Trudeau's updates to see his hair go through various stages of the lockdown

From a purely physical standpoint, Trudeau's locks seem to have become a sort of hourglass for which Canadians can observe how long the lockdown as gone on. 

Two months ago i pledged to not get my hair cut until justin trudeau did. Today, i am honoured to announce that i am still upholding that pledge. And that is a wonderful thing.

As Trudeau continues to make headlines with several now-iconic moments over the past few months, including a clip of him flipping his hair that went viral, many around the world have started to notice what we Canadians already know: the man has objectively great hair.

Trudeau's speeches and blackface shit aside, for a moment, I can't help but laugh every time there's new pictures of him, during the pandemic. The longer this man's hair gets, the more thirsty ppl get lmao. pic.twitter.com/FCuoFrYCoz

His hair and its increasing length have been the subject of not one, not two, but three major articles examining how it's begun to serve as a reliable measurement for tracing this moment in time.

Trudeau’s really getting to the full lego man hair level now. pic.twitter.com/TK9T6Xadbw

Not everyone agrees, however, that Trudeau's hair is a worthy subject given that there are so many more important things going on in the world right now, or that it deserves the symbolic status to represent our temporal experience of time.

And some First Nations communities in Canada have not had clean drinking water since before the pandemic. (https://t.co/oGTxaJsLaz) But, sure, let's talk about how long it's been since Trudeau cut his hair. https://t.co/MENsbbylIy

At the risk of getting too scholarly, it may be best to leave the topic of time and the strongest tool for measuring it up to the individual. 

my lockdown hair is at that crucial point where it could go one of two ways, either Justin Trudeau chic or Joe Exotic mullet, only time will tell

And anyway, with more hairdressers, barbers and salons set to reopen in some provinces, Trudeau could soon return to his pre-pandemic tidy schoolboy cut.
