Experts have warned that women who make regular use of hair extensions run the risk developing bald spots.
Hair restoration surgeon Dr Bessam Farjo revealed girls as young as 20 were left in need of hair transplant surgery after trying to ape the style of celebrities such as X Factor judge Cheryl Cole and Victoria Beckham.

"Hair transplant surgery may seem like an extreme solution but it can be the only way to restore hair permanently," the Daily Express quoted Farjo as saying.
Actress Jennifer Aniston recently said: "Nothing destroys your hair faster than extensions."
