The second installment in the Cool Chix series, Hair Trix for Cool Chix is a fun, hip guide to haircare and hairstyles for today's trend-conscious tween. This friendly book features more than 30 step-by-step projects to help tweens and teens create cool hairstyles for all lengths and textures of hair. Girls start by taking a short quiz to figure out what kind of style they are looking for-basic styles like ponytails and twists; slightly more complicated styles still right for daytime; or special-occasion styles like updos and glam waves. They can then take the quiz again the next day to find a whole new look! Sections like "Hairology 101," "Get Salon Savvy," and "Hair 911" offer loads of hair-related information, from tips on caring for various hair types to simple explanations of haircare products and appliances, to solutions for hair emergencies like greasy roots and static electricity. There are even recipes for mixing up at-home hair treats and step-by-step projects for making cool hair accessories. This one-stop guide will give tweens and teens everything they need for a hip, healthy head of hair!
