What is the one routine or treatment or process (beauty related) that gives you happiness deep down to your bones?  You get a spring in your step and a song in your heart? Makes you feel like THE diva of the day? For me it has to be related to my hair. Any form of pampering from a simple cut to getting it colored or going all the way with a luxurious Kerastase ritual just makes my day. I feel all of 16 again :).
