Soy\'s phytoestrogens do alter estrogen levels, depending on how much you eat.

Whether that would affect your eyelashes, I cannot say. Normally, hormonal hair loss/growth affects the whole body. One sided eyelash loss sounds more in line with an infection, viral or bacterial, or possibly a change in the blood flow on that side.

I hope this helps.
