Glad you asked...
You can hypnotize females or males with a little talent. The idea of hypnosis is to tap into a person's subconscious mind. Once you have tapped into their subconscious mind, you can change their thoughts or beliefs about something. If you want a girl to like you, you may try to tap into her subconscious mind and share things about yourself that she would like, or try to change her idea about you. The person being hypnotized also has to be receptive, in order for the process to work. You can find more information here:
