Experiences of discrimination and acculturation are known to have a detrimental effect on a person's health. For pregnant women, these painful experiences can also affect the brain circuitry of their children, a new study finds.

Hair products often contain ingredients that easily evaporate, so users may inhale some of these chemicals, potentially posing health repercussions. Now, researchers have studied emissions of these volatile organic compounds (VOCs), including siloxanes, which shine and smooth hair. The scientists report that using these hair care products can change indoor air composition quickly, and common heat styling techniques -- straightening and curling -- increase VOC levels even more.
