unfortunately i was attacked by someone a while ago now with a crash helmet. i thought i would post on here as really worried hair isn’t going to grow back properly and the scar is going to show for the rest of my life!
That scar looks very pink so I dont think it was that long ago that it happened? If hair grew there before your accident then it should grow back and the scar should fade.
However that could be the start of your hair thinning ,but that will not be because of the injury,its just normal male hair pattern.
The short answer is maybe or maybe not. I think the scarring will go down, and the hair will grow back, but the scarring will not fully and completely go down. I still have the scar from 12 years ago, when i was attacked.
