Supermodel Miranda Kerr says she has an obsession for clean hair and has a strict shower regime to wash her locks. The 30-year-old also mentioned that she uses coconut oil and conditioner to get shiny hair, reports contactmusic.com. “Hair-wise, I love using coconut oil as a treatment and apple cider vinegar for shininess. You put on a little bit in the shower as a rinse and then wash it out,” Kerr said. “It stinks a little, but then you use conditioner and the smell goes away. I’m obsessed with having clean hair,” she added.
