Does anyone else have this problem? Usually a few times a week while running my fingers through my hair, I'll find random strands of thick course ( sort of all kinky ) black strands of hair. Does anyone know what causes this? I have natural curly hair so originally I thought it had something to do with that but I pulled one out one day to look at it more closely and it was pitch black ... my hair is light brown. It was all ridged and course.
