The ITV soap will resume filming this week after production was halted in March due to the coronavirus pandemic, but now bosses have reportedly warned actors to ensure there are no continuity errors with their new 'dos.

A source told The Sun Online: "They were asked at the outset to be mindful of big style changes - a crazy haircut like going bald all over for the blokes or bright green hair for the ladies. Or even the other way round!!

"The writers don't need the added headache of having to explain some homemade haircut in new storylines when filming resumes."

Some cobbles stars - such as Alexandra Mardell (Emma Brooker), Sue Cleaver (Eileen Grimshaw) and Tina O'Brien (Sarah Platt) - used the break as an opportunity to dye their hair, while Simon Gregson (Steve McDonald) shaved his hair off.

However, bosses aren't too concerned.

A spokesperson added: "The cast are sensible and mindful of the fact that they are returning to work.

"It is evident from all their social media posts that no one has done anything extreme at all."

While the experts won't be able to actually style the actors and actresses, they'll be on hand to offer guidance to those who need it when filming resumes on June 9th.

The source said: "When they call for costume and makeup checks they'll radio through whether the actor needs to put their hair behind their ear or whatever the direction is.

"Costumes will be left outside an actor's dressing room the night before filming."
