Balding is not abnormal. Going completely bald is abnormal. What you have looks to be normal hair loss that most men suffer as they age. There's no telling if it will stop at a little recession, or if you'll go on to become a NW3 or NW7, but you have miniaturization. It's up to you if you want to get on finasteride as a preventative measure or wait and see if your recession gets bad, or if you start losing hair on top.
