The new analyze “suits in perfectly” with that in general body of analysis, stated Alexis Temkin, a toxicologist with the nonprofit Environmental Performing Group in Washington, D.C.

It inbound links hair product use to hormonal variances that are dependable with some of the overall health outcomes that have been tied to this sort of products and solutions, according to Temkin.

The findings — posted in the journal Environmental Analysis — are based mostly on one,070 expecting women of all ages in Puerto Rico who produced up to a few analyze visits above the system of their pregnancy. They done questionnaires on personalized product use and gave blood samples to have their hormone amounts calculated.

All round, amounts of estrogen, progesterone and testosterone were being lessen among the women of all ages who claimed employing “other” hair products and solutions, compared to nonusers. That classification included dyes, straighteners, bleaches and mousse, but not shampoo, conditioner, hair spray or hair gel.

It’s not obvious, according to Rivera-Nunez, no matter if women of all ages who use these hair products and solutions may be exposed to unique chemicals that are problematic, or have a better amount of publicity to endocrine disruptors.

Beyond that, there are quite a few factors that may sway pregnancy hormones. The researchers factored in the variables that they could — this sort of as women’s pre-pregnancy body pounds, income and education amounts, as perfectly as their using tobacco and consuming heritage.

But it is really not attainable to account for almost everything, Rivera-Nunez stated.

For now, she advisable that women of all ages who are expecting or organizing a pregnancy read through labels and be aware of what they are putting on their bodies. At the identical, she acknowledged that these labels are not essentially consumer-friendly.

“The deficiency of superior labeling is a issue,” Rivera-Nunez stated.

Temkin recommended on the lookout out for the phrase “fragrance” — a harmless-sounding time period that really contains a broad range of undisclosed chemicals, some of which may well be endocrine disruptors.
