Sophie Ellis-Bextor knows what it's like to lose some of her hair after pregnancy, which is why she is a great fit to represent haircare company Nioxin. The brand is dedicated to thickening and making hair look and feel fuller with six three-part systems. Sophie never straightens her hair or uses product, but she really loves having nice hair. In a press release she said, "I am so happy to be Nioxin's UK and Ireland Ambassador. I've been using Nioxin for a while now and have really felt the difference in my hair. It feels stronger and thicker and have noticed how shiny it has become."
