Catherine Zeta-Jones

Catherine Zeta-Jones credits shampooing with truffles and smearing beluga caviar in her hair for her shiny locks. The $400 caviar is flown in five days before her treatment to a beauty salon where she sips champagne and eats caviar canapes while being groomed.

“Catherine discovered the caviar treatment last summer and was astounded by the difference it made to her hair,” said a source.

“She has an incredibly rich and vibrant natural hair colour but the creamy, almost oily nature of caviar really brings this out, making the colour even richer and making it so much more glossy.

“The eggs are packed with omega-3 fatty acids necessary for the formation of structural proteins. It is these proteins that repair dry and damaged hair and smooth over any split ends.”

You wanna know what else works really well? Fresh human placenta. Yep, placenta gives my hair its vibrant color and extra bounce. It’s because placenta is packed with similar nutrients. Nutrients like omega-3 fatty acids and, uh, uterus juice.
