Naomi Campbell reveals shocking bald patches on Ibiza holiday

London, Aug 10 (ANI): Naomi Campbell revealed her incredibly receding hairline - the result of her over-reliance on hair extensions and weaves for most of her modelling career - during her holiday in Ibiza earlier this week.

While the 42-year-old supermodel still looked in great shape in her patterned bikini, all attention was focused on her hairline, with her exposed scalp causing concern.

This is not the first time Campbell has sparked concern with her thinning hair, with experts saying she is suffering from traction alopecia - hair loss caused by the use of extensions, the Daily Mail reported.

The supermodel, originally from Streatham, South London, has worn straight extensions over her naturally curly hair for a number of years.

Traction alopecia occurs when the extensions pull on the natural hair causing it to break, and usually affects the hairline just above the forehead or the sides, where the hair is weaker.

It can take between three months to a year for hair to grow back in moderate cases.

But if the pulling continues the hair will never grow back and the only option is a hair transplant.

Stars including Paris Hilton, Victoria Beckham, Britney Spears and Alexandra Burke are all reported to have suffered traction alopecia as a result of hair extensions.

Celebrity hair extensions expert Tatiana Karelina, who counts famous faces including Danielle O'Hara, Stacey Solomon and Lauren Goodger among her clients, said of Campbell's condition: "The interesting thing to note is that traction alopecia doesn't progress like other hair diseases.

"At the initial stages it is reversible but prolonged tension may destroys the hair follicles and will not re-grow under any circumstances.

"It is unclear from the pictures if Naomi's condition is permanent but given the time that has passed since she was first spotted with this condition it is more than likely that the damage she has suffered is permanent," she added. (ANI)
