I have a 1-inch cut on my head, about 1 inch above my forehead, hairline. It occurred 48 hours ago, and in retrospect I should have gone to a doctor then to see if I needed stitches/ staples. I was playing around with a friend's dog and we butted heads at one point. (I'm truthfully not sure if it was the dog's hard head or his teeth that got me, but I'd guess it'd be more likely to be a tooth. I know that this dog is free of any disease such as rabies).

The cut bled profusely for a few minutes, but then mostly stopped save for slight oozing of thick blood at the deepest part of the cut which gradually tapered off within a few hours.

At this point, the wound is closed, and doesn't feel like it is likely to reopen. Most of the cut is not so deep, save for a ~2 mm gash at the end. I've been washing it and applying neosporin twice a day to curb any risk of infection.

I'm concerned though, about a scar on my scalp and how that could affect hair growth. (The cut is in a fairly visible part of my head). Is there anything I, or a doctor, could do to aid in healing and prevent scars or any noticeable damage to hair growth?

I'm aware that it's probably too late to stitch the wound, but is there anything a doctor could do - such as reopen the wound and stitch/ staple? Or are there any over the counter methods I could use that may be similarly effective?
