Expecting? Ditch the hairspray

Baby & Toddler
Pregnant women have been warned against using hairspray, because new evidence suggests that chemicals they contain may be linked to an increasingly common birth defect in boys.

Paediatricians have suggested that using sprays – and also some colouring shampoos – could raise the risk of the genital condition hypospadias.

The alert comes after a study showed that mothers who had used hair cosmetics during pregnancy were nearly twice as likely to have a boy with the condition.

Pregnant women have been warned against using hairspray, because new evidence suggests that chemicals they contain may be linked to an increasingly common birth defect in boys.

One theory is that chemicals in the products disrupt male hormones and interfere with the development of the male genitalia in the crucial first three months of the pregnancy.

“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,” say the researchers, whose study is published in the International Journal Of Environmental Research And Public Health.

Hypospadias affects about one in 250 men.

One of the main features is that the urine opening – called the meatus – emerges on the shaft or even the base of the penis, instead of at the tip.

The condition is also linked with undescended testes and fertility problems.

The team of doctors which carried out the research say that exposure to endocrine-disrupting chemicals in the womb could adversely affect the development of genitalia during early pregnancy.

The study at Amiens University Hospital in France involved comparing the use of hair cosmetics, chemicals and pesticides in 250 women who had given birth to boys with and without hypospadias. No association was found between hypospadias and the use of chemicals such as paint, solvents, petrol, ink, glue and household products, but the use of hair cosmetic was found to raise the risk by 80 percent.

Support for the theory comes from previous research.

One study reported a significant association between maternal occupational exposure to hairsprays in manufacturing plants and risk of hypospadias, while a second found an increased risk of newborns with hypospadias in women hairdressers.
