According to charity Jeena International, some salons are prepared to slash their prices by as much as £30 when treating young girls because they were "likely to be less developed than older people".
"This is beauty obsession gone wild!"
Shockingly just one in 25 salons refused to carry out the intimate hair removal procedure on a child, with Jeena it has uncovered "a form of cultural-driven abuse", reports Metro.
Rani Bilkhu, founder of charity Jeena International, told the newspaper: "This raises further questions of normalising girls to culturally harmful practices, objectifying them and girls not being allowed to celebrate their bodies changing."

According to The Metro, Ms Bilkhu decided to investigate the worrying trend after hearing the shrieks of a 9-year-old girl undergoing a bikini wax near her home in Slough.
She called salons posing as a mother trying to book in her pre-teen daughter for a Hollywood wax - but just 4% of salons refused to wax a child.
Beliefnet.com columnist Linda Mintle has slammed the practise, writing: "How does a young girl learn to like her body, flaws and all, when her mother is taking her for 'treatments' [so young]?"

"This is beauty obsession gone wild! Children are already bombarded with repeated images of what they are supposed to look like and know they will never measure up. Every day, they face a culture obsessed with cloning Barbie."
However Deborah Morris, from beauty salon group BABTAC, argued that waxing a girl so young could help those who hit puberty early.
"We advise our members to assess the client on the basis of need."
