Lady Gaga is the worst celebrity for torturing her hair in the name of beauty, and Rihanna, Britney Spears and Katy Perry are also identified in a survey as suffering for their looks.
The Pantene Torture Test surveyed 561 New Zealand women about their hair habits and the role models they saw as doing damage to their locks.
Thirty-six per cent voted for Gaga, a natural brunette, who highly styles and bleaches her locks, 14 per cent for Rihanna, 9 per cent for Spears (who has also gone skinhead) and 8 per cent for the multi-coloured Perry.
Nearly 50 per cent admitted they used hot styling tools at least once a week. Thirteen per cent admitted they used a hot iron daily or more frequently, while 8 per cent said they used them once a month.
A total of 61 per cent admitted they had suffered a "hair disaster".
The survey, carried out by a market research company for Pantene, was conducted last month.
It also asked women what they believed could torture their hair the most - bleaching or the overuse of hot styling tools.
Forty-one per cent said the bleach bottle was the lethal weapon, while 26 per cent of women said repeated use of heated styling tools had the most potential to wreck hair.
Shoreh Barkhordari, a senior stylist at Rodney Wayne Albany, said older women who came to their salon tended to have healthier hair than some young women.
"It depends on hair type and style. The young people tend to use straighteners more often - they like their hair straight all the time.
"When the fashions and the colours change, we get a lot of people who come in to dye their hair constantly. That's not necessarily bad, but we do give them advice."
Another stylist, Aucklander Joy Mati, said times had changed and teenage girls and young women were more aware about taking care of their locks.
However, those who religiously used hot irons and straighteners should be warned.
"If they don't know what happens now, they'll find out soon. [Constant use] will wreck their hair," she said.
"It can dry out your hair and strip it of nutrients. It slowly singes your hair. ... The hair, from scalp down to mid-length, will look healthy. But the tips will look dry."
