Idk. I tend to believe that her texture is the result of 'soft' hair being heat damaged (press and curls for your whole life). I have elders in my family that fit her general profile and none of their (many, so a wide sample lol) kids ended up with 'good' hair. We do, however, have that soft, fine hair that relaxes and straightens )too) fast and easy.But she had that "good" hurr!
Somebody posted an article a while back on a black man who had comandeered a slave ship and freed everybody (iirc). In the contemporary news article, it was noted that all the fancy negros in NY had come out to fete him, especially the women who wore every bit of finery and frippery they owned.Beautiful. I doubt that hair was a concern for the struggle we had to deal with back in the day so it was easy to just put it away yet still be elegant.
All of the older women on my mother's maternal side wore their hair the same way. It stayed in a bun, or two French braids.No, I met her in person when I was a child and my father knew her much longer--her hair wasn't heat damaged. In fact she just washed and bun all the time. My MIL was also like that and would only use paper bag "rollers" to curl her hair.
