TL,
Sorry to hear you fell at the hands of the infamous Bosley, me too..
It all depends on the scars width and position on scalp as to the best way to approach minimising them.
Options :
1. Scar revision. Possible if positioned ok and you have enough laxity.
2. FUE into the scars can really help minimise the scar - I had this done into my old Bosley scar.
3. You could also look at tattooing the scar as an option.
Hope this helps
