I have had a few scalp surgeries....They're only visible if you look at my head up close, but to answer your question, Cortisone cream, Mederma Scar Cream and Aloe Vera is what I use. As a black man, if I want to "mask" said scars, I've been using BB cream on my scalp. This was recommended by our brother KDusk. Regular use of BB cream will eventually help the scars blend in with the rest of your scalp, but I think Cortisone cream used regularly is the best route. If you want your scar to flatten faster, get Band-Aid blister ampoules and wear them to bed over your scars every night. Good luck, brother and PM me if you have any questions. Side note: Scars are what make our heads ours, I wouldn't lose any sleep over them.
