Andrew Collinge, who owns a chain of British salons, said the survey of 300 women found respondents changed the layering, color or length of their hair an average twice a year between the ages of 13 and 65, The Sun reported Wednesday. Advertisement Collinge said one-third of those polled said they change hairstyles to mark the end of a relationship and 12 percent said they change hairdos to mark milestone birthdays. The poll found 69 percent of the women wore long hair with a fringe at least once in the past, while 66 percent wore their hair in a bob in the past and 61 percent had sported long layers.
