Coronation Street fans were left confused tonight, after spotting a strange change in Dr Ali.

Tonight saw the Dr struggle to get his hands on some painkillers, after his supplier at the hospital was arrested.

His addiction to painkillers has remained hidden until now, but today's episode saw him become sweaty and clammy as he tried various ways to get the drugs he needed.

He was even outed by Dr Gaddas, who said she would help him and that everyone can suffer with addiction.

But it wasn't that which caused viewers concern - they were more worried about why his hair kept changing in every scene.

In one scene it was parted one way, in another scene it went in the other direction and then there was no parting at all.

And fans were quick to point out the blunder on social media.

Tony Scullion said: "Ali's hair is now combed straight back, in the cafe it had a side part!! Ali and her every scene changing hair do!!"

Suzanne said: "The prescription drugs are playing havoc with Ali’s hair."

Pamela said: "What on earth is going on with Ali's hairstyle. It keeps changing. It's freaking me out."
