That's the definition of 4a...4a is smaller than pencil size to coffee stirrer size and smaller. The definition of 4B is hair that is fluffy with no curl pattern, even when stretched. All the number/letters have range so if you see ppl with bigger curls/coils, you might be the same hair type or they may have mistyped themselves. Have you seen the pen spring thread? Lots of 4as have pen springs.

The number/letters are only about curl circumference. Ppl who say they are 4C+ tend to cite their reasons being that they have no curl/coil whatsoever or their hair is "very nappy." How fine or coarse the hair is, is irrelevant. If there's no curl/coil pattern, its 4B.

The difference between a pencil diameter and a coffee stirrer diameter is huge, imo. And as such, I believe it calls for another category...5. I consider myself a 5C, since I have very small coils, with no definition, even soaking wet/with product. And even have to be careful with my twist outs.

Circumference: Crochet needle or even smaller

I always thought that coffee stirrer or pen spring size was 4a, I believe that is the original definition.

I agree with Nappy*Me and the others who say there is no such thing as 4c hair. The picture of her hair is exactly what I think of when I think of 4b hair.

BUT - I think this thread once again proves why the hair typing system is erroneous, because there are always going to be outliers, and if it's a "true" system, people can't just make up additional hair types because they don't feel as if they belong in any of the categories. Also, since hair typing doesn't take texture into consideration, a lot of people don't realize that your hair can look VERY different due to texture, but you will still fall into the same category as someone else.

And, what is this Z pattern coil they keep referring to? My hair has a round coil pattern, no sharp angles. Yet has no definition. So, I'm not 4A, because I have no definition, and I'm not 4B, because I have no Z pattern. So, where does that leave me?
