A new study has suggested that baby boys born to women who use hairspray regularly during pregnancy have an increased risk of developing a common birth defect.


The study, conducted at the Amiens University Hospital in France, and published in the International Journal of Environmental Research and Public Health, revealed that the chemicals present in hairspray were linked to the condition, hypospadias.



The results showed that women who used hairspray regularly were nearly 50 percent more likely to give birth to boys with the birth defect.


The condition means the opening of urethra is found on the underside of the penis, rather than at the tip and is said to effect 0.4 percent of men.



The study found that the chemicals present in hairspray had an impact on male hormones and caused problems with the development of male genitals.


"This is the first study to demonstrate a link between maternal household exposure to these two hair cosmetics during early pregnancy and the incidence of hypospadias," said the medical staff who conducted the study.


"The precautionary principle should apply to pregnant women and they should be advised to limit their use of hair cosmetic."
