Ink stains are tricky, but they sometimes respond to alcohol. Alcohol content in hair spray has been greatly reduced since my junior high days of poofed-up bangs. This is great for hair-care. Not so fab for ink stains.
Sometimes hair spray works. And when it does, it's wonderful. But a lot of times, it doesn't. Hair spray tends to work better if the fabric in question is made of polyester or a polyester blend. That being said, clothing treated with hair spray should be rinsed thoroughly whether the ink came out or not.
