I've been thinking about this a lot lately, for a few reasons. For one thing, seeing people identify what looks like the same texture by different numbers. Then, I thought I had it down from Naturally Curly, but when I checked out Hairveda's site this week, their descriptions made it sound like I had 3c, since my curls are either dense waves or defined coils, not Z pattern.
I always assumed I had about the most coarse/densely curled hair there was, from what hair stylists told me and all the "you don't look mixed, look at your hair." But when I think back to some of the black boys I knew growing up (since girls were mostly pressed, relaxed or jherried) and my own natural hair from 1995-2004, it wasn't the same. I remember Eddie Murphy had a bit about getting teased for having "peas" in the back. I didn't have peas, but I had tight, springy coils.
It was only after the BC that I learned I had different textures, because stick straight hairs would stick out of my TWA. My dad's half sister BC'd a few years before me and I wondered why my TWA didn't look the same. I only found out a few years ago that her father was light skinned, so she has what was referred to as mixed hair when I was growing up, 3b/c, pencil-sized coils that are shiny and smooth. I remember my hairdresser not wanting to relax my aunt's hair in the '80s, because she was convinced it had already been relaxed. Now that all makes sense. Her half brother has wavy hair that kind of curled up at the ends. I never saw a photo of her with her natural texture, only pressed or relaxed, so it looked a lot like 4abz hair that's been relaxed.
Mom has THICK, wavy 2a hair (though one side's gone stick straight in recent years, to her dismay). It's kind of coarse. Her dad had wavy blond hair that no one inherited, her mom had thick, wavy/curly black hair. I'm quite convinced they were Jewish or Italian and passing as Irish. In more fanciful moments, I wonder if my grandmother was actually part black and passing. I just see pics of her from the '40s with other teenagers and she looks really "ethnic" in comparison. Even my mom is olive-skinned and tans well --not generally an Irish trait!
I'd say dad was 4a (defined coils), fine and thin. His parents were, I think, both 4a/b, with the fine/thin hair running on his mom's side.
Mine seems like a mixture of mostly dad's texture and mom's super thickness with some of her textures all over, not concentrated in certain sections. I thought the type 1 hairs were just up top with the fine, wavy hairs that I barely relax, but yesterday I pulled a fine, silky, stick straight hair out of "the kitchen."
My brother has my mom's hair color (darkest brown, she gets offended when people say it's black). It was 3b/c bouncy ringlets when he was a kid, it got coarse during puberty, but I think the curl pattern remained the same. Not sure, since he inherited our uncles' receding hairline and shaves it close.
