A woman died from a massive allergic reaction that could have been caused by the glue in her hair extensions, a pathologist said.
Atasha Graham, 34, who had used hair extensions for 14 years, collapsed after clubbing until the early hours.
Pathologist Michael Heath told the inquest into her death that the latex glue used to apply her extensions - or the solvent for removing old ones - may have been to blame.
"I've seen cases where people using solvent to apply extensions has actually caused anaphylactic shock," Dr Heath told the hearing at Southwark Coroner's Court in London.
"There are about ten to 20 deaths a year in this country, many more in America. I have seen four in the last three months."
