Singer and Herbal Essences spokeswoman Nicole Scherzinger turns 41 today. Nicole's birthday is one of my favorites to celebrate each year and you'll see below why. Besides her incredible beauty and killer body, her unbelievably gorgeous, long, dark hair is some of the best around. Her hair has it all - rich color, silky soft texture, incredible shine, long length etc. So Nicole and her hair especially deserve the best treatment for her birthday as well as every day in general.
