Beyonce's hairy situation...

When it comes to glue, Beyonce seems to have trouble avoiding sticky situations.

Earlier this month, she appeared at the Dreamgirls premiere with a patch of oddly marked skin on her cleavage which seemed to be the result of overzealous application of sticky tape.

Now during a performance at a concert in Florida, she appeared onstage with bizarrely bunched up skin by her hairline, after glue had been applied too tightly to hold her hair in position.

The 25-year-old singer is believed to favour a special type of hair extension-where real human hair is woven and glued into her own locks.

But if the hair is fixed too tightly, this unsightly 'varicose vein' effect can result.

Although Beyonce's hair extensions have been badly fitted on this occasion, other celebrities have suffered far more in their quest for a long flowing mane.

Earlier this month for example, actress Kate Beckinsale was pictured with bald patches on the back of her head-an unfortunate hazard of hair extensions.

And celebrities including Victoria Beckham and Nancy Dell'Olio have also suffered baldness when their real hair was ripped out along with the extensions.

Commenting on the danger of this practice, expert Glen Lyons of the Philip Kingsley

Trichological Clinic in London said: "Although techniques have improved, the potential damage caused by traction- the pulling of the attachment from the glue-remains."

Beyonce performed a number of songs at the Florida concert earlier this month, which was televised for the World Christmas Day Parade and aired in the US yesterday.
