Switching to organic personal care products can significantly reduce the level of hormone-disrupting chemicals in your body in as quickly as three days per the results of a study published in March 2016. Collaborators on the study included UC Berkeley. The chemicals to avoid include phthalates (such as diethyl phthalate), parabens (such as methyl and propyl parabens), triclosan, and oxybenzone (aka benzophenone-3, BP-3).
