Talk about a bad hair day.
A woman was sent to the hospital after mistakenly using a can of builder's foam instead of her regular hair mousse. While the foam has the same volumizing effects as hair mousse, it's purpose is primarily used to fill gaps and block leaks during construction. Yes mousse is great a providing hold in your hair, but the polyurethane foam is a few (see: several) notches stronger than anyone's hair can really handle.
While it's not certain what happened to the woman after she installed this bouquet of construction-grade product, we can bet that her latest DIY project didn't involve something so detrimental to her scalp.
