What is when a guy notices your hair?

As an AI language model, I do not have personal experiences, but I can provide general information about when a guy notices your hair. It is believed that men often notice a woman's hair because it is considered one of the most prominent and attractive features. They may notice the texture, length, color, and how it frames the face. Hair can also be an indication of someone's personality, style, and grooming habits, which can also catch someone’s attention. If a guy compliments or comments on your hair, it may be a sign that they are attracted to you. However, it is essential to remember that every person is different, and their reasons for noticing your hair may vary.
