What's the trending hair colour at bb right now? Red! After recently blonde bb Australia Managing Director Sarah decided to dye her locks a red-toned shade (which definitely gets the bb tick of approval) we thought we'd take a walk down memory lane and review our five fav stars who've rocked red in their manes, plus, how to care for your locks should you dare...

Blake Lively

Blake took her famous 'Serena Van Der Woodsen' locks a lush orange red and paired it with an aquamarine dress on the RC to showcase it. We think this shade suited her blue/green peepers to perfection. She kept the rest of her beauty look simple, so the paps would make her new hair the hot story. However, a little wash of bronze shadow on her lids compliments the warm look of her style. For a similar look, try the Glamourflague Gypsy Jo Eyeshadow and plenty of  black mascara to define lashes!

Whitney Port

Similarly, Whitney - also famous for her blonde tendrils - took the plunge into russet territory a few years back. With blonde pieces still peeking through, and a whole lot of voluminous extentions to bulk up her natural fine and silken hair, we think it's a fun change for the reality TV nice - and super fashionable - girl. Her bronzed cheeks are our next favourite part of this look. Try the Talavou Naturals Illuminisor for a little shimmer and colour at the same time.

Drew Barrymore

Of course, Miss. Drew wouldn't be afraid to go red - or black, or brown or peroxide as past styles have shown! And this deeper, darker orange red is worn with absolute confidence. I love the pairing of the pink lip colour and a little smudged liner. It keeps the red of her hair gorgeously fresh and girly. Try the MeMeMe Poppy Cheek and Lip Tint for a similar look. 

Khloe Kardashian

Who'da thunk that we'd ever see a Kardashian with red hair?! Even though it was very short lived (she died it back almost immeadiately after this appearance) we think Khloe did red well! Maybe a little less eyeliner would've really taken the look up a notch, but we do love her peachy lip tone here. OCC do a great orangy-peach in ChaCha, plus a range of other bold shades to suit red heads and creamy complexions. Take a look! And have you also heard the rumour that the ladies Kardashian aren't allowed to dramatically change their hair (like chopping it all off). I have and thinks it's cray cray! I'd be much more likely to tune into KUWTK to see a bob on Kim or blonde locks on Kourt!

Now, a few tips if you are considering going red... 

1. Red pigments are light-sensitive, so you should take care to keep your hair out of the sun, otherwise it can fade. Also, use hair care products, which protect against UV rays, or wear a hat to cover you hair, especially in summer!

2. After colouring your hair red you shouldn't swim in a chlorinated pool for up to two weeks - chlorinated water is even more stripping on red hair colour.

3. Speaking of water - try to wash infrequently. The more times you wash, the more your hair will fade. Invest in a good dry shampoo to go that extra day between washes. Also try to limit using heat styling tools. They can be twice as damaging on hair that's been colour treated, which is why it's a great idea to invest in a conditioning treatment like the Royal Moroccan Hair Mask Treatment.

4. Even with the best of care, red hair fades between colour treatments. But rather than hitting the salon again, you can use a colour rinse in the matching shade at home in the shower. The rinse maintains the brilliance of the red colour, and will give you a few extra weeks before forking out at the hairdressers!

Would you ever consider going red? Perhaps you have before? And tell me, would you ever sign a contract like the Kardashians to keep your hair the same? Let me know - Lauren
