2014, you have certainly made us expect the unexpected when it comes to hair color. A few years ago it would have been wild to spot green hair on the street, but today we wouldn鈥檛 look twice. Every color of the rainbow has been spotted this year 鈥 and not just on Katy Perry. We鈥檙e all about the uncommon colors, and it鈥檚 looking like we might have one more to look forward to. Metallic hair seems to be the next dye job on the rise, at least in London.

Hari鈥檚 Salon on King鈥檚 Road is making its mark on the beauty industry with its new buzzworthy color. 鈥淲e were seeing a lot of metallics trending in fashion and we thought, Hmm, why not hair?鈥 Mel Halacoglu, a senior colorist at the salon tells Style.com. Falling somewhere in between ash and platinum, this particular shade of bronze helps 鈥渢one down full-on blonds, as well as softly lightening winter brunettes,鈥 she explains.

While there isn鈥檛 any actual metal in the dye, Mel says she uses the 鈥渂alayage technique鈥 to apply the exclusive golden-honey hue 鈥 a shade popular with models weaning themselves off bleach. The technique is known for instantly adding radiance to dull strands and warmth to complexion. Looks like you can ditch the bronzer. Currently this shimmery dye job is only available across the pond, but we鈥檙e guessing it will make its way stateside in the not-so-distant future.

In the meantime, all this talk about hair color has us thinking about which colors made it big in 2014. Considering we鈥檝e kind of seen it all this year, it was hard to narrow it down, but we did our best. Here are a few of our favorite hair color trends of this past year (most of which will probably keep going strong in 2015).

1. Rose Gold: Not quite bronze, but metallic in its own right, we鈥檙e expecting to see a lot more of this color in 2015. Rumer Willis shows off the brassy tone that鈥檚 a mix between red, pink and yellow. Consider it an updated version of strawberry blonde. (image via Just Jared)

2. Lilac: Considering lilac鈥檚 cousin Radiant Orchid was color of the year in 2014, we can鈥檛 say we were surprised to see this shade explode. Vibrant enough to make an impact without hurting everyone鈥檚 eyes, this color is the perfect first step into colored locks. (image via Pastel Illusions)

3. Ash Brown: If you鈥檙e bored of basic brown hair, give it an edge with this dusty, ash brown color. It鈥檚 the perfect, albeit subtle, adjustment for a winter 鈥榙o. (via Style.com)

4. Silver: Gray hair isn鈥檛 just for grannies anymore. This hair color (or lack thereof) is making an impact on a dramatically younger generation. Whether you go for a deeper shade of gray of a shimmery silver is up to you. (image via Lux and Laune)

5. Glitter Hair: As a not-so-permanent option, glittered hair seems to be taking off. Whether you dip your whole head in the stuff or simply add a little bit of sparkle to a select section, this style is certain to cause a stir at any party you rock it at. (image via Nasty Gal)

6. Colored Dip Dye: Whether it鈥檚 pink, green, or jade blue, one thing became very clear this year: dip dying is not just for fabric anymore. (image via @kyliejenner)

7. All the Colors: Why have one color when you can have them all? From a two-toned ombre to a full-blown color explosion, this look is certainly for the brave, but also the beautiful. (via Culture and Life)

8. Babylights: If you鈥檙e not familiar with the term, babylights are delicate blonde highlights painted on using the balayage technique 鈥 the same way that bronze hair is created. The process gives hair color dimension, sort of like a blonde kid鈥檚 hair at the end of summer. Falling on the totally opposite side of the hair color spectrum, the technique used this way is designed to make hair look as natural as possible. (via @dominikagrnova)
