10 gorgeous gwen stefani hairstyles

She's always been one of our biggest style crushes so to celebrate her 45th birthday (no, really) here are ten of the most memorable Gwen Stefani hairstyles from her career in music. From her now-iconic bleach blonde shade to her early days with a Cookie-Monster blue 'do, Gwen has never been shy of experimenting with her look. As her style has effortlessly transformed from rockabilly to retro queen to immaculate working mom, her hair has switched up too - the entire look always works, from head to toe. Here, we take a look back at ten of the best Gwen looks - which is your favourite? Cookie Monster blue In the early days of No Doubt, it wasn't just Gwen's abs that we were jealous of - her ability to carry off Muppet-esque blue hair also had us feeling envious. The matte finish and rough twisted buns feel incredibly fresh today - so very East London... As is that faux fur bra. Alien braids The sci-fi, slightly alien feel of these braids prove that Gwen isn't just about retro-inspired updos and all-out glamour. There's a real high-fashion feel to these tight, arching plaits which we've seen elements of on the catwalks at Alexander McQueen, DKNY and Kenzo. The Mr Whippy Taking the retro quiff to a new level, this rolled-up Mr Whippy style is pure Gwen-style individuality.  With the rest of her hair pulled back into a sleek ponytail, the style has just enough impact to have wow-factor but enough cool to not look costumey. The Bjork buns We're self-confessed mini-bun lovers and this is quite possible where the love affair started. A classic Gwen look from the early No Doubt days, this twisty updo remains one of our favourite styles - and it's one that she's been revisiting recently too. The Croydon facelift Not many women can pull of a seriously strict Croydon facelift, but as we're learning, Gwen isn't just any woman. This super-tight, scraped-back look gets a twist with the braided band, wrapped around the base of the pony and left loose. The Jean Harlow It's only fitting that Gwen Stefani was cast as Jean Harlow in The Aviator; both of them were iconic blondes for an entire generation. Jean Harlow was known as the first blonde bombshell and made platinum popular in the 1930s - although in pre-peroxide days, it was bleach and washing powder that was (shockingly!) used to achieve her shade. The Must-Have Colour She might be one of showbiz's most iconic blondes these days, but this pink hair shade from 1999 set a generation of teen girls on the hunt for Manic Panic dye. The Elvira Elvira Hancock is arguably the most stylish thing about Scarface, and it was she who Gwen turned to when choosing a new look in 2006. The sleek tucked-under ends and lash-tickling fringe are key to this look, which Gwen embodied throughout the promo for her Sweet Escape album. Pin-Up Pretty Gwen has always had a knack with retro, pin-up girl looks and these 1940s-inspired Victory Rolls are no exception. Glamazon  Gwen just keeps getting better and even when she's rocking something simple like a ponytail there's not a hair out of place. Never a hint of roots either - does this woman have an in-house colourist?
