How can you punch up the tones of your red hair? Ortiz is a firm believer in cranberry or pomegranate juice as a hair treatment. He says, “It stains the hair and makes it rich.” Just apply it, leave it on for 20 minutes and then rinse off and style as usual. And unless you want your shirt to look like a piece of evidence in a murder trial, try wearing something dark while you “treat” yourself.
