Matt Smithhas a face made for film and TV, one that the camera can’t help but focus in on, which has ensured fans have gotten a good look at the actor’s mug, and many have noticed that Smith’s eyebrows have thinned to the point they’re almost not even there. Smith has had a meteoric rise to stardom, beginning in the 2010s. First, he became known to a select, but fervent, group of fans when he took on the role of the Eleventh Doctor, one of the morelikable variants in theDoctor Whofranchise.

As popular as he was inDoctor Who, it was his performance in the first two seasons ofThe Crown, as Prince Philip, that showcased just how talented of an actor he is. Films likeLast Night in SohoandMorbiuspaved the way for what is currently his crowning achievement,Daemon Targaryen inHouse of the Dragon. As one of the biggest television stars working, it’s natural thata lot of aspects of Matt Smith have come under scrutiny, including his eyebrows, which at least one fan has a theory about.

Unfortunately for those curious, Matt Smith has never publicly addressed slowly losing his eyebrows over the years. Of course, it’s clearly occurring. One only needs to look at Smith at the beginning ofDoctor Whoto Smith in the second season ofHouse of the Dragonto see the difference, even accounting for Daemon’s blonde hair. Despite Smith never discussing his eyebrow hair loss,Doctor Whodid reference his thinning eyebrows in Matt Smith’s final regular appearance in the series.

In “The Time of the Doctor”, the 2013 Christmas Special, the Eleventh Doctor shows up with a bald head. When Clara (Jenna Coleman) asks him why he shaved, he simply responds that he was bored. Clara innocently asks if that’s what happened to his eyebrows. Offended, the Eleventh Doctor denies touching them, saying they’re “just delicate”. In reality, Smith had his head shaved for his role as the Bully inRyan Gosling’s directorial debut,Lost River(2014).

The mention of eyebrows may have just been a little ribbing joke at Smith’s expense, one he clearly didn’t mind considering his willingness to participate.

TikToker Charles Peralo Has A Theory That Matt Smith Has Madarosis

Madarosis Is A Health Condition That Can Cause Eyebrow Hair Loss

A TikTok user has a theory about what happened to Matt Smith’s eyebrows, and they took to the social media platform to explain their findings.@charlesperaloposted a video showing how Smith’s eyebrows have nearly all but disappeared over the years, first considering alopecia, a condition that causes those who have it to lose their hair (viaAAD). However, people with alopecia tend to lose all their hair, not just their eyebrow hair. So@charlesperalo suggests Smith has madarosis, a health condition that can result in the loss of eyelashes and eyebrows (viaNationalLibraryOfMedicine).

@charlesperalo claims that the condition affects 1 in 500 people, though that number does not appear to be supported by most reputable medical journals, a signal that perhaps TikTok is not the best source to find medical information. It’s also good to note that Smith does still have some eyebrow hair; it’s not completely gone. It could simply be genetics, andMatt Smith’s eyebrows simply thin fast. It doesn’t seem to bother the actor too much and there is a whole lot more to the actor than the density of hair on his face.
