We covet their cuts as celebrities, but what about their locks before they were A-list?

Christina Ricci

Christina’s been famous pretty much her whole life, but back in those awkward teenage years, we bet she would have loved to hide from the cameras. Before she found her beauty look, she often suffered from looking a little bit ‘90s Goth, with that dark black hair and pale skin. Fast forward to today, and she’s got really flattering honey-coloured hair and tanned skin.

Sandra Bullock has definitely had some shocking moments on the red carpet, but she’s also had her fair share of smoking hot ones too. When she first rose to stardom, she had a badly cut, very big hair style full of school girl curls. Now, she’s gone for longer layers and length and found the hair straighteners, whilst also toning down the extreme make-up.

Julianne Moore looked pretty scary in the olden days – but now she’s super swish with her darker red locks and straightened ‘do replacing that strawberry blonde frizz.

Mousy brown and preppy long, pre-Friends Jen's hair didn't warrant a sentence of praise let alone the subsequent acres of news print.

Pre-Hollywood, Kate's hair was more Transylvania than Transatlantic, goth black and veering from super-sized and randomly pinned up, to severely cropped and texturised.

The curls remain, but SJP has learned to loosen up and most importantly lose the oh-so unflattering bouffant motif at the crown.

Dire combination of wispy fringe and thick one length hair conspire to make Natalie look bland and anonymous. Scissors saved her.

Her trademark luxe colour, but I spy a root perm and some scrunch drying. Luckily her Friends put her right.

A blonde Venus today, but adolescent Scarlett falls into the teenage-going-on-30 trap of overdone ‘hooker' hair and too much make-up.

The poodle perm, the khaki blonde, the mumsy fringe, pre-pop minx Kylie goes for broke in the hideous hair stakes.

We have our doubts about Gwen's No Doubt bleached blonde crop, contemporary yes, but a statement of iconic Fifties cool? No way.

Renée's big movie break and yet her hair's in nipping to the newsagents mode. She has since learned to reliably channel Hollywood retro chic.

Before she decided to Get Smart and wear Prada, Anne enjoyed a Woodstock moment. Tucking hair behind both lugs is risky and she looks positively Lineker-esque.

Centre parting, stiff waves and gaudy '70s style frock, is Dawson's Creek era Katie auditioning for Abigail's Party, The Movie?

These days she's the new red carpet queen of the famous bob, but pre-Housewives Eva's tortured, spiky style is desperately trashy.
