"Dreadlocks Skeeve Me Out"

Last night while my roommate was braiding my hair so I could wash it she said something that kind of annoyed and offended me a bit. We were talking about locks and she said "I don't know, I never really liked dreadlocks, they kind of skeeve me out." Of course I inquired into why they "skeeve" her out and she said because they're "dirty" and that grosses her out. I asked further into why she seemed to think your hair was dirty if you had locks and she said "Well isn't that how you get your hair into dreadlocks?" Obviously she wasn't including me in this because she knew I was about to wash my hair but we have 2 friends who both have locks (very nice locks, I might add) and this whole time she was thinking that they had dirty hair?

I always knew that it was a common misconception that people thought that individuals with locks did not wash their hair but i didn't know it was that common. The hair actually needs to be clean and oil free in order to not disturb the locking process, right? That is something I am pretty sure goes for all locks...not just sisterlocks. It just kind of surprised me hearing something like that because she has so many African American/Black friends (she's Caucasion) that I would think she would have asked by now. I schooled her though so now she knows that locked heads do not equal dirty heads.
