it sort of looks like a scar but I dont see it in any of the Oscar pics.

black women might be more susceptible due to all the weaves, etc. There is something called traction alopecia

I looked at some pics of people with alopecia. a lot of it is in round type patches and not a straight line...leading me to think it might be due to traction alopecia

Had my hair platted for a week in college... my black female friends wanted to do it...I could feel the traction. They do this under the theory that it speeds hair growth.

If 'traction alopecia' really is a thing - your thought is very plausible.
