Shaun Williamson thinks his acting career has improved since he's had his hair transplant.

The 51-year-old actor underwent the procedure shortly after he left 'EastEnders' in 2004 because he didn't want to be stuck with a "short, fat, bald" tag for the rest of his professional career after portraying bumbling idiot Barry Evans in the soap since 1994.

And, although it's been a long process waiting for his locks to grow, he's already noticed such an improvement in the different job roles he's being offered.

He told the MailOnline: "Very slowly my new hair started to grow through. It was such a gradual and natural process that people who saw me regularly didn't even notice. You don't have to suffer in silence, there really is a cure. I'm delighted with it. I feel it has given me greater versatility as an actor. I don't want to be stuck with a "short, fat, bald" tag forever."

Although he's worked hard to change his image, Shaun couldn't help but smile when he entered the 'Celebrity Big Brother' house earlier this week to fans chanting "Barry."

However, he's no doubt hoping to show viewers the real him during his time in the famous abode, although he got off on the wrong foot with one of his fellow housemates.

The legendary actor was the first contestant to enter the building on August 1 and was immediately summoned to the diary room to be set the first challenge of the series.

Shaun had to convince all of his housemates that he was the most nervous contestant as well as persuade Brandi Glanville to pour water over his head, cuddle Derek Acorah and follow Sandi Bogle around until bosses told him to stop in order to win a reward.

Shaun failed the task and was told he had to make a killer nomination, in which he chose 'Mob Wives' star Marissa Jade, meaning she's the first to face eviction this week.
