ITV boss John Whiston has confessed Emmerdale cast members have caused trouble for bosses and script writers.
The show recently recommenced filming amid the coronavirus lockdown, having halted filming in March.
Amid fears the soap would go off air and run out of episodes filmed before the COVID-19 restrictions came into place, the ITV soap later revealed this would not happen.
They've had limited cast members and staff back at the studio for the past few weeks, filming special lockdown episodes - while Emmerdale will only air twice a week from Monday.
But with selected characters back and filming scenes with the backdrop of the coronavirus pandemic, there's been a few issues.
Obviously the episodes airing now, which run out this week, were filmed back in early March.
Filming only recently started up, but new episodes will be airing from Monday.
During the lockdown months, some cast members decided to shake things up with their looks.
Danny Miller, who plays Aaron Dingle, shaved his head - as did Jamie Tate actor Alexander Lincoln and Matthew Wolfenden who plays David Metcalfe.
Some cast members have also dyed their hair, with Victoria Sugden actress Isabel Hodgins going very blonde - while over on Coronation Street, Emma brooker actress Alexandra Mardell dyed hers purple and then blue.
With Danny one of the first to return to set, bosses have been forced to explain why Aaron suddenly has no hair within a matter of episodes.
Both Emmerdale and Corrie are having to make some additions to the script, to clear things up.
John told Lorraine Kelly on her show on Wednesday: "You can also see my biggest problem right there with Aaron's haircut.
"Most of the cast for some reason decided to shave their heads, and all the female cast decided to dye their hair puce.
"It was a problem with everyone coming back to work. How did his hair get like that?
"We've had to put in loads of lines in on how he got his hair like it."
Emmerdale airs Mondays, Wednesdays and Fridays at 7pm on ITV.
