This is what NC says on type 4 hair -
Type 4 is kinky, or very tightly curled, with a clearly visible curl pattern

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?

I also think they were referring to the length of the needle and not the hook on the end - I can picture it in my head but I don't think I can describe it well. 4a hair also does not have to be clearly defined - if you have a round coil pattern, you have a curl pattern. I haven't seen your hair but by your description I would call you 4a. Whether your hair looks defined and clumps together depends on texture/density.

And regarding the crochet hook, they were using it as a guide for circumference, which is a huge factor in hair-typing. You can't just say crochet hook, and expect everyone to know which size, you know? When you say pen-spring, or straw those are pretty standard. But crochet hook is not. I think this a key point, so, it's not really over-thinking.

An illustration...



Any old way, I have some pen-spring coil, no definition-even-with-product, kinky, motherland, super-shrinking, gravity-mocking, true afro hair.
