Initially, the claim was made by sex therapist and former comedian Pamela Stephenson, 59, who said that ladies who cut their hair are deliberately making themselves less sexy to blokes.
However, now the theory has got scientific backing after experts claimed that the links between long hair and sex go back to caveman times, reports the Daily Star.
Dr Pam Spurr, a relationships expert, said: “The woman who no longer wants sex uses a haircut to show she’s reclaiming power in the bedroom.
“For women, hair is a reflection of the person, of her moods and her self-esteem.”
Relationship psychologist Anjula Mutanda added: “Cave paintings celebrated long-haired women – the longer the hair the more fertile and, therefore, desirable she was.”
But body language and behaviour expert Judy James disagrees, saying: “The only thing it symbolises these days is the shutting off of childhood. In terms of sex, I would argue it has the opposite effect.”
