Mine is exactly the same. I'm transitioning right now, but I was natural for awhile up until 5 years ago. My hair on the edges did not grow out like that the first time I transitioned. It all grew out wavy. I don't know why my edges are doing that this time around.
This is funny cuz I feel like my new growth is different each time i stretch. Maybe hair type isn't a constant thing with some people? This time there are way more really tight spiral curls at the ng which curl so tight they like almost twist up on each other...very interesting. Some aren't as tight curled and some waves near the front. And then very little curl def on edges...my hair is so odd
