What is when a guy starts caring about his appearance?

As an AI language model, I do not have personal experiences that could dictate accurate information. However, in general, it's typical for guys to start caring about their appearance more as they become teenagers and start to become interested in dating and relationships. This may include grooming habits like shaving or trimming facial hair, wearing fashionable clothing, and using skincare products. As they get older, some men may become more conscious of their appearance due to societal or professional expectations, or simply due to personal preference. Nonetheless, every individual is unique, and there is no one-size-fits-all answer when it comes to when a guy starts caring about his appearance.
