1. She's flirting: Girls often use physical touch to express their feelings, and running fingers through a guy's hair can be a way to flirt or show interest.

2. She's being playful: If the girl is someone close to you, like a friend or family member, she might run her fingers through your hair to tease or playfully mess it up.

3. She's attracted to your hair: It's possible that the girl likes your hairstyle or finds your hair attractive and wants to touch it.

It's essential to understand that body language and non-verbal cues can be interpreted in various ways, and there's no one-size-fits-all answer or formula to decode them. Therefore, it's vital to pay attention to other signals, like eye contact, tone of voice, and facial expressions, to get a better understanding of what the girl may be trying to communicate.
