Since then, he's made the best of it, but now has finally been able to grow a bit of facial hair.
He shared his results on social media, posting a picture of his 'first ever moustache' that has successfully sprouted from his face during the third national lockdown in England.
Lucas, who obviously takes poking fun at himself within his stride, made a joke to his Twitter followers about how disproportionate his facial hair is, and poked fun at the fact that it looks a little bit strange because he doesn't have any eyebrows to go with it.
Lucas wrote: "In lockdown 3 I grew my first ever moustache.
"I don't have eyebrows so it looks a bit weird."
Hey, there are those of us out there who can't grow good facial hair without having battled against alopecia and the results of a childhood trauma.
It was the car accident as a young boy that led Lucas to lose all of his hair, although the funnyman has revealed that enduring such a dramatic change at such a tender age has helped shape him into the person he now is.
Speaking on The Jonathan Ross Show, he explained how he gradually started finding bits of hair on his pillow, and thought nothing more of it, until it continued to happen and he had no hair left altogether.
After visiting 'countless' doctors, Lucas was finally told that it was the shock of the car incident in Portugal that had caused the hair loss.
However, he has turned that trauma into strength over the years.
He explained: "I started out actually always in character because I think growing up, I lost my hair when I was six.
"I was ashamed of being gay, struggled with weight. Other challenging things happened in the family. I wanted to be a stand-up comedian.
"I felt I could be more honest in character than I could be as myself."
Well, this moustache isn't much, but it's a start. Perhaps he'll start growing more and more facial hair and we'll see a hilariously hirsute Lucas on our screens before too long.
