Yeah, a lot of women have traction alopecia, I'd even say the majority of them do. I swear, next time look at the hairline of a chick who has had a lot of weaves/braids in her life, you'll see the hairline is back further than you'd expect.
i've been noticed, its a sad sight. i have an ocd issue where i try to decipher how many black women are natural vs weaves, perms, wigs.
