"When someone does something head first, it means they are doing it with a lot of enthusiasm and without thinking too much. It is often used to describe someone who is eager to try new things, take risks, or dive into a situation without being cautious. An example could be, "She jumped head first into the project, without knowing all the details." This expression is usually used informally and is not related to physically putting your head first into something."
