Although big bouncy hair might be all the rage lately, there's no denying the sophistication of a smooth sleek look.

Smooth straight hair reflects shine so when you style your hair this way, it's going to look healthy and ideally like you just walked out of the salon. Now, this particular look does require a certain amount of practice as you need to blow-dry it before straightening, all while using the right products. Once you've mastered it, straight smooth hair is an elegant, timeless, reliable style that never ever goes out of fashion. With that in mind, I've chosen five celebrities who are giving me major straight hair inspo. Penelope Cruz Penelope is rarely spotted with a hair out of place and her straight, smooth locks are seriously gorgeous. Pictured at the Zoolander premiere recently, this metallic dress sets off her dark locks and HOW shiny does her hair look?! Goals. Kendall Jenner Kendall is a firm favourite on my style crush list for both fashion and beauty and I don't think I'm alone in saying so. The model's brunette hair complements her smoky eye makeup and the overall effect, with THAT dress, is just fabulous. Beyoncé Darker hair often looks shinier than blonde but not so with Queen B. Long (LONG) straight hair sometimes runs the risk of looking straggly and unkempt but not so with B. Rather than want to cut it, I just want to imitate her look and am frantically googling 'ways to make your hair grow' as I type. Ashley Greene Twilight star Ashley has fab hair altogether and often changes it up from darker to lighter shades by subtly adding a few highlights. She often sports pretty waves but in the below photo, she's opted for a sleek style and I'm obsessed with it. ANOTHER celeb style to perfect. Sarah Jessica Parker  Okay. the below isn't exactly straight but it's smooth and I absolutely love it. SJP is another famous face with serious style kudos and every Carrie Bradshaw fan wants to emulate her look. For this style, you'll want to blow-dry your hair smooth and then use a curling tongs/GHDs to add a couple of loose waves. Want smooth, gorgeously sleek hair?
