James Corden revealed controversial shower habit that experts swear against

James Corden, who returned to our screens last night in a truly incredible episode of Gavin and Stacey, has a very unique shower routine.

Living in a world of beauty products, it's easy to get swept up in a 10 step routine for each part of the grooming process - but perhaps the secret to becoming a world famous celebrity is not partaking in such trends.

The 46-year-old actor and Carpool Karaoke host previously revealed his grooming habits - and it will probably surprise you.

In reality, the star is miles apart from his Gavin and Stacey character Smithy - who would happily forgo daily showers.

We're constantly being fed information about how often to clean ourselves, and how often we should wash our locks, so it's pretty normal to end up with our own makeshift routine.

While some people swear by washing their hair each and every day, others (me) opt for every few days.

I'd love to say it's for the benefits, but it's sheer laziness.

Corden, on the other hand, takes things to the extreme.

Speaking on his talk show in 2022, The Late Late Show, he revealed that the time he spends in the shower is a lot less than the average.

According to the Centers for Disease Control and Prevention (CDC), the average shower time is eight minutes.

Corden admitted: "I’m in and out [of the shower] in a solid three or four."

The conversation was brought up due to LA locals being told at the time to cut down their shower durations to preserve water.

The chat then moved on to hair washing, and Corden left his colleagues stunned when he revealed how long he goes without shampooing.

He said: "I use soap, but I don’t wash my hair.

"I wash it every two months.

"That is a true story.:

His colleagues joked that he was 'dirty' and 'nasty', which prompted people on X to post in agreement.

“Yuck! That is nasty,” commented one person, while someone else simply replied: “Ew.”

Experts have suggested the exact amount of time you should leave your hair before washing it, but at the end of the day, we're always going to throw it in a messy bun if we just can't be bothered.

Trichologist (total hair expert and scalp expert) Anabel Kingsley, of haircare brand Philip Kingsley, gave her expert advice to Glamour about the truth of washing and conditioning your hair.

“I would not go for more than three days between washes,” Kingsley said, explaining that going any longer can be damaging for our scalps.

“Your scalp is skin and needs similar care to the skin on your face - and for scalp health, daily cleansing is best,” she clarified.

“You take your hair and scalp to the same places you take your face and they get just as dirty.

"You wouldn’t go for days on end without washing your face (especially if you live in a city) - so why would you do that to your scalp?”
