To keep her famous blonde mane sleek and shiny it was Kiehl's Creme with Silk Groom. This item is a cult favourite of sorts today and can be used as a leave-in-conditioner or as a styling creme. I know Kiehl's makes really good anti aging products (I'm a big fan of their Ultra Facial Cream) so I'm sure this hair creme works wonders.

She was also a fan of Philip Kingsley's hair products. Remember, when your'e not naturally Scandinavian blonde, all of that dying and bleaching really takes a toll on your scalp. Hence Philip K's Moisturizing Shampoo and Conditioner, to tame split ends and repair damage, as well as the Elasticizer to smooth and strengthen hair.
