Newly appointed L'Oreal spokeswoman and TV personality, Alexa Chung offered up  a few of her views on hair and the many do's and don'ts. Check out a few of the funny, and somewhat true tips she shared below.

Hairstyles and lipstick go hand in hand. Chung never leaves home in a topknot without her lipstick. "Sometimes I've been known to try a topknot, but because I'm obsessed with balancing things out, I'll only wear a topknot with lipstick. Without lipstick on, you're just looking at the topknot."

Bad mood equals bad haircut. Chung warns to wrap police caution tape around your head if you're in a bad mood and contemplating a haircut pick-me-up. "Hair is so linked to how we feel and everyone goes for something radical after a break-up, but my advice if you've just suffered heartbreak or you've broken up with someone, is to not touch your hair ... you're not in a fit state to make decisions that are long-term - you'll have to spend the next four years growing it out. Don't have a fringe cut. Don't bleach it. Don't do anything, because you will regret it. Buy a lipstick instead. I always think people's hair looks really weird when they're sad anyway. When my friends are heartbroken I can tell that they're sad; their hair just starts looking a bit forlorn. Like when Britney Spears got sad and shaved off her hair. That's the ultimate warning - heed that. If you're not feeling good don't do anything to your hair."

Blondes do have more fun- at least after a long flight. Chung suggests everyone else better bring a hat. "Blonde hair seems to just travel really well. If you've got dark, fine hair like mine, then you'll always look crap at the end of a flight, but blondes step off the plane looking really nice and fresh. I fly a lot, so I notice these things. I'd also advise taking a hat when you're traveling - you'll also look slightly like you're in a band at the airport. I might actually consider keeping my luggage in a guitar case one day.
