Documentarian Louis Theroux has asked fans for some advice as he shares his latest alopecia health update.

The 53-year-old revealed he “probably” had the hair-loss condition back in January this year.

He previously posted on Instagram: “So this is what my beard grows like now due to what I think is probably alopecia.

“Basically I get a little triangle of stubble around my mouth and some more at the sides.

“It’s not a big deal, but I don’t want people to think I’m doing something creative with my facial hair and doing it badly, when it’s just what I look like when I don’t shave."

He added: “This is also why I don’t wear a beard as much anymore. Maybe it’ll grow back. Who knows?

“It mainly happened over the course of 2022. You get a sense of how it progressed from the other two photos taken six months before and a year before.”

Louis Theroux asks fans for advice in alopecia update

In his latest post on the social media app, he asked his 840k followers for some advice regarding hair loss on his eyebrows.

Louis can be seen raising his eyebrows in a video, along with the caption that reads: “I’d like to know how I’m supposed to continue a career based largely on raising and lowering different eyebrows WITHOUT ANY EYEBROWS!! #alopecia I’m seriously thinking of getting them tattooed back on but it feels like a big step! Thoughts?”

Offering their advice, one person commented underneath: "Go for it! I had my eyebrows tattooed on, they look real. Eyebrow tattoo artists are so skilled at making it look really natural.”

Also giving their thoughts, someone wrote: “I had mine tattooed at 15 when my hair all first fell out and they’ve never come back and it’s made my life so much easier and given me so much confidence. I miss my eyelashes terrible x”

This fan recommended: “Try an eyebrow pencil to see what you think and then Go for it louis x”

Giving Louis a confidence boost, this user said: “You slay with and without the brows queen.”

“You've got such an expressive face as it is! Eyebrows or no eyebrows,” added another.

How do I know if I have alopecia?

There are different types of alopecia, and various medical conditions that cause hair loss, according to Alopecia UK.

The charity says: “The word ‘alopecia’ simply means hair loss. If you are experiencing any more hair loss than what is normal for you, you are experiencing some type of alopecia. The next step is identifying which type of alopecia you have.

“We recommend you first speak to a GP. If your GP is unable to make a diagnosis, they may refer you to a dermatologist.

“Please note, ‘alopecia’ is often used by doctors as an abbreviated way to discuss ‘alopecia areata’.

“This can be confusing when there are different types of alopecia too! If in any doubt as to what type of alopecia your GP is referring to, ask them to clarify.”
