You like the way your hair looks. Like it and have fun and be excited about it!
Your friend has different thoughts...about hair and about a lot of things. Her feelings.. are about her and are for her to deal with.
Sounds as if she's just in the process of adjusting to it, not that she doesn't like it.. it just feels 'weird' to her right now because it's new, but soon it will be familiar to her so it won't feel weird to her. Everything will be okay.
Enjoy your new hairstyle!
