Hello George, This is not possible to tell by looking at the photos. You can have a scalp evaluation done by a hair doctor online or offline. He/She will be closely able to monitor your scalp and would be able to tell the difference. But in order to prevent this hairline from growing, I would recommend eating healthy and nutritious food and also using hair products that are holistic, don't use products that have so many chemicals in them. If you need any more guidance, you can visit a trichologist or a dermatologist near you. Thanks!
