Celebrity hair transformations never fail to catch us off guard. Just when we’re getting used to a celebrity's signature look, they give themselves a fringe, chop off all of their hair or dye it a completely different colour.

The latest hair transformation comes courtesy of Dame Helen Mirren who debuted her new blue hairdo at the 2023 Cannes Film Festival.

The actor’s vibrantly hued hair matched her powder blue gown – but she’s not the only celebrity who has surprised us with a dramatic hair transformation in recent years.

From Julia Robert’s fringe, to Florence Pugh’s shaved head and Stacey Solomon’s stint as a redhead, here are the most memorable celebrity hair transformations.

While the actor has been growing out her hair since the beginning of the pandemic, the blue hue is the first time she’s experimented with colour in recent memory. She debuted the look at the 2023 Cannes Film Festival.

After having a signature hairdo of big bouncy curls in the ‘80s and ‘90s, Julia Roberts experimented with her hair colours for a while before landing on the look she’s worn for the past decade or so: soft reddish-brown waves with a centre parting. Only this year has she switched things up yet again with a new fringe that she debuted in March.
