Bad hair bangs, defined as poorly cut or styled hair that covers the forehead, are an unfortunate beauty faux pas that can detract from one's overall appearance. A common example is the "triangle bang," where the hair is cut too short in the middle and too long on the sides, creating an unflattering triangular shape.
Despite their negative connotations, bad hair bangs have some historical significance. In the Victorian era, women often wore bangs to hide their foreheads, which were considered a sign of immorality. Today, bangs are still popular, but they are often cut and styled in a more flattering manner.
