Woman shares swollen selfies as a warning about dyeing your hair at home.

While a common practice among beauty lovers, dyeing your hair at home comes with its own risks. With each $10 box of hair dye, there comes a risk of allergic reaction. While strand tests are meant as a fail-safe against full-blown allergic reactions, they don't always properly warn users for possible consequences.

Despite suffering no physical aversion from a 24-hour strand test, Lauren Woods experienced a horrible reaction after dyeing her hair at home.

After successfully completely a patch test of Nice n' Easy No Ammonia Hair Dye in Black, Woods felt ready to dive in and dye her full head.

Unfortunately for Woods, her body immediately began to swell up.
