What is if a guy compliments your hair does he like you?

As an AI language model, I don't have personal experiences but generally speaking, if a guy compliments your hair, it could be a sign that he likes you. It shows that he's paying attention to you and taking notice of small details about your appearance. However, it's important to not read too much into one compliment and consider other aspects of his behavior towards you. Keep in mind that every person is different and may show their interest in various ways.
