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.
對于喜歡洗牛奶浴的（埃及女王）克利奧帕特拉來說，普通的水一定不能滿足她的要求。

凱瑟琳·澤塔-瓊斯對于洗發(fā)水和護發(fā)用品的要求與此如出一轍。

我們大多數(shù)人也就用用一般的洗發(fā)水，而這位威爾士影星則用松露和魚子醬。

她一次護發(fā)用的魚子醬就需要200英鎊--看來美麗是要付出代價的！

而澤塔-瓊斯則將她那一頭極有光澤的褐色秀發(fā)歸功于這一美食。

一位消息人士說：“凱瑟琳去年夏天發(fā)現(xiàn)魚子醬護發(fā)品之后，便十分驚訝于這種東西給頭發(fā)帶來的變化。”

“多油的魚子醬使她原本色澤飽滿、自然鮮亮的秀發(fā)更加飽滿、亮澤。”

“魚子醬中富含的多不飽和脂肪酸是合成結(jié)構(gòu)蛋白所需的主要物質(zhì)。而結(jié)構(gòu)蛋白的作用就是修復(fù)干枯、受損發(fā)質(zhì)以及消除分叉。”

澤塔-瓊斯用富含松露的洗發(fā)水洗發(fā)，然后抹上魚子醬、將其梳勻后再晾一會。

與很多流行的護發(fā)用品不同的是，魚子醬被證明具有護理治療的功效。它所富含的基本脂肪酸所產(chǎn)生的膠原質(zhì)和角蛋白兩種蛋白質(zhì)是使頭發(fā)光滑亮澤的主要物質(zhì)。

2005年，這位曾出演過電影《五月花》的女星在Sunsilk公司和倫敦城市大學(xué)聯(lián)合開展的一項全國性的調(diào)查中，被評為“頭發(fā)最美”的名人。
