Plain water wasn't good enough for Cleopatra, who 
 preferred to bathe in asses' milk.
 Catherine Zeta-Jones, it would seem, has a similar attitude to 
 shampoo and conditioner. 
 
While most of us have to make do with a handful of fragrant soapy 
 foam, the Welsh actress smears on truffles and caviar. 
 
At £ 
 200 a time, just for the fish eggs, looking good does not come 
 cheap. 
 
But she credits the gourmet delights for giving her long brown 
 tresses an unbeatable shine. 
 
"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 color but 
 the creamy, almost oily nature of caviar really brings this out, 
 making the color 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." 
 
Miss Zeta-Jones's hair is washed with a truffle-based shampoo, 
 then smeared with the caviar and which is combed through and left to 
 set. 
 
Unlike many fad treatments, caviar is actually proven to work as 
 a conditioning therapy. The essential fatty acids it contains 
 produce collagen and keratin, two proteins vital for the appearance 
 of sleek hair. 
 
In 2005, the former Darling Buds Of May star was voted the 
 celebrity with the "best dressed" hair in a nationwide survey by 
 Sunsilk and London's City University.
