Top 10 Haircuts and Colours Right Now

A far cry from the '90s-era "Rachel" cut, the 2017 shag hits at the collarbone and gives a slight nod the the '70s. "Once your lob gets too long, you can layer it into a shag, and it's the perfect length," says Gregory Russell, who created Chloe Moretz's look.

Keeping the ends at a uniform level gives a cut like Michelle Obama's a classic, polished finish. "What's great about the blunt cut is that it can be worn sleek, but also with beach waves or a deconstructed texture," says Tyler Colton, hairstylist for Honey Artists. "If you have an oval-shaped face, definitely go longer between the jaw and collarbone. Long faces should take the blunt cut closer to the jawline."

By keeping the layers longer in the front, short crops like Viola Davis's serve up endless styling possibilities, from effortless and side-parted to swept back in a sky-high pompadour.

Gone are the days of contrasting platinum on brunette colour schemes. By giving your highlights a metallic bronzed finish, a la Chrissy Teigen, the overall effect is more subtle, and your skin gets an extra touch of warmth. "It's the kind of hair colour that will make your girlfriends ask where you went on vacation over the weekend," says colorist Lila Carlino of New York City's Julien Farel Salon. "Think of a rich base with ribbons of caramel, to light golden-blonde at the very ends."

Not too cool, not too warm, a neutral auburn base like Emma Roberts's is just right for all skin tones. Because the shade is so vibrant, we recommend using a colour-depositing conditioner every time you lather up. Red is the largest hair colour molecule, and is prone to fading faster than other shades, but can stay fresh til your next appointment with the right after care.

Truth be told, the long bob has been a popular look for what seems like eons. For a low-key finish, opt for staggered layers like Olivia Munn's, which look equally great either styled or air-dried.

The change is subtle, but it's there. By fine-tuning Kerry Washington's natural brunette a touch toward sienna, her hairstylist Takisha Sturdivant-Drew was able to play up the golden hints in her skin.

In the creative colour realm, rose gold is still going strong. Instead of a pastel pink on a blonde base, true rose gold tones like Lady Gaga's incorporate warm copper hints into the mix—you know, like every piece currently in your jewellery box.

A wispy set like Emilia Clarke's are super-versatile and look great against any face shape, but create a balancing act in particular for long and heart silhouettes. Ask for a length that just hits the brow area, so you can either wear them to the front, or swept to the side.

That blonde ambition is stronger than ever this year, with even typically-brunette stars like Katy Perry crossing over to the lighter end of the spectrum. Make sure your hair colourist picks a hue that flatters your complexion—cool skin pairs well with Perry's icy shade, whereas warmer tones should opt for a slight honey tint.
