Lifechangers: Nurse Jamie Road Tests Hair Oils

Long sexy tresses are hot in Hollywood these days. How do stars keep all that hair looking healthy and shiny? This week, "Extra" Lifechanger Nurse Jamie Sherrill talks about one of the hottest trends in hair -- hair oils.

"There is the common misconception that topical oils are absorbed into the hair making it healthier, which is not exactly true," Nurse Jamie explained. "Hair is made of protein filaments -- not live cells -- so once it leaves the hair shaft the benefit of the oil is to smooth the hair cuticle and protect it. The chemical make up of some oils make them structurally better at penetrating the hair shaft than others and provide different benefits."

Here are some great tips and products for the best-looking hair!
