Megan Fox just debuted a bright blue bob for spring

Megan Fox is well on her way to completing the rainbow with her hair colour. After rocking silver, platinum blonde, copper, cherry cola red, and, most recently, cotton candy pink, the actor is adopting a whole new hue for spring—and it's (almost) all the way across the colour wheel.

Because while the Jennifer's Body star is known and beloved for cycling through various shades of blonde, pink, and red, this time she's choosing to dive headfirst into ice-cold Titanic waters (IYKYK). Megan's new hair is not only much shorter—her just-past-the-shoulder-length shag chopped into a sleek, blunt bob—but dyed an ultra-icy shade of bright electric blue too.

I'm not sure what it means, but I'm confident it means something: This is the first time the actor has ever rocked blue hair to my knowledge (I say this with utmost confidence; I consider myself a Megan Fox scholar). It is the first day of Mercury retrograde, after all. (Reddit detectives, do your thing.)

While we may not know the meaning behind Megan's new aesthetic, we do know how she got the look. Megan's cut and colour are courtesy of her go-to stylist, Dimitris Giannetos, who's overseen all of her hair transformations, from blonde to red to pink and so on. Fortunately, he was generous enough to share behind-the-scenes photos of and how he achieved her metamorphosis.

According to Dimitris, who is calling the shade blue jeans, he achieved Megan's icy electric shade using none other than — gasp — box dye. More specifically, he dyed Megan's previously pink hair using L'Oréal Paris Feria Multi-Faceted Shimmering Permanent Hair Color in shade 411 Sapphire Smoke, which L'Oréal describes as a “smoky blue.”

While we love a DIY-friendly hair transformation, I feel it's my duty as a beauty editor to clarify one thing: Dimitris was able to achieve such a dramatic hair change with just box dye because Megan's hair was already light (and likely bleached prior to being dyed pink). Translation? If your hair is currently blonde or on the light side, you're good to go and grab that box dye.

If your hair is any darker, however — and especially as dark as Megan's natural colour — we strongly encourage seeing a professional colourist to gradually lighten your hair. Generally, pros advise against exceeding more than four levels of lightening in one salon visit.

But of course, always feel free to use Megan Fox as beauty and hair colour inspiration. I know I do.
