Elle only has to crack open a cold beer to get the secret ingredient to lush locks.

Victoria Beckham, 40, is rumoured to keep her perfect porcelain skin in tip-top shape by getting Japanese facials with an extra special ingredient – bird poop. Geisha Facials as they are called use nightingale droppings to form a cleansing paste. Sounds gross, but apparently it works!

Scarlett Johansson, 29, revealed in an interview that she cleanses her face with cider vinegar. “I researched natural skincare and found that apple cider vinegar is really effective. Using it as a toner can be harsh, but if you have breakouts it can be really healing.”

Catherine Zeta-Jones, 44, has found another use for the humble strawberry – she uses them to whiten her teeth. “The juice or pulp of strawberries contains malic acid which serves as an astringent and can lighten surface stains,” she said.

While on The Late Show in New York, Demi Moore, 51, told talk show host David Letterman she used leeches to detox. “I was in Austria doing a cleanse and part of the treatment was leech therapy,” admitted the mother-of-three in her 2008 interview. “These are not some low-level scavengers – we’re talking high-level blood suckers.” According to the actress the slimy insects release enzymes in the blood which optimise health.

Cindy Crawford, 48, supposedly sprays plain milk mist on her face to keep it hydrated. While it may be a bit on the nose there might be some magic behind this madness as milk is full of minerals, protein and calcium, all of which are essential for healthy skin.

Zoe Saldana credits her bohemian mother’s mayonnaise for her beautiful shiny hair. “My mother was a hippie and very health conscious, so growing up, she always encouraged my sisters and I to be as natural as possible,” says the 35-year-old. “She gave us a book she bought at a garage sale about natural beauty remedies and we used to look up everything, like how to make masks out of oatmeal or give our hair highlights using henna tea or even rum. Once a year, we all still get together and put mayonnaise in our hair for old times’ sake.”

Teri Hatcher, 49, once told Britain’s Daily Telegraph that she pours a glass of red into her bath every day for its skin-softening effects. The Desperate Housewives star believes her youthful complexion is enhanced with the antioxidants found in the vino’s grapeseed oil.

Funny woman Sandra Bullock, 49, confessed to using haemorrhoid cream under her eyes to reduce puffiness. “I didn’t realise that putting haemorrhoid ointment on your face is acceptable in the beauty business,” says Sandra. “But apparently, butt cream helps lines around the eyes!”

On a 2010 episode of her show The Price of Beauty, Jessica Simpson, 33, tested out a rather ticklish Japanese foot treatment known as a fish pedicure. During this spa treatment feet are submerged in water filled pint-size piranhas that nibble away the dead skin leaving it soft and smooth.
