New year, new you? Let's all agree to forget the unrealistic diet plan and instead embrace a beauty upgrade that provides instant confidence-boosting results. We are, of course, talking about your hair. If you've been going low-maintenance for a while, it's miraculous what a fresh cut and some new highlights can do for both your mood and your look. And where else would you treat yourself to a chic coiffure than at one of the fanciest celeb-frequented salons in the city? Trust, your 'do will thank you.
