I've tried reading this article several times before, but for some reason it always freezes on my computer so I still have not read it from beginning to end in one sitting. I do believe that it has a lot of information, and there is much that I learned.
However, hair typing is extremely confusing to me, and I feel as if it is actually impossible to do, at least as far as curl pattern is concerned. If you look at the individual hairs on my son's head, he has a combination of straight, wavy, looser curls, and tight coils. He also has one straight white hair and one straight red hair. When you look at his hair as a whole you can see that he has a clear curl pattern without the use of products - actually his curl pattern is more clear when clean and wet than after it dries and is moisturized, although you can always discern a curl pattern overall. So I guess that would make him type 3 although he does not have the silky curls that you would normally associate with type 3 hair. And you can easily pick his hair out into a fro although his hair always curls back up, but from a distance it still looks like a fro.
I'm transitioning so I'm still trying to learn about my hair. What is interesting to me is that I finally decided that I might have type 4A hair but now I just don't know, and I do not believe I will even try to type my hair any more. After reading the article I realized that my hair on my edges, which is the most difficult hair for me to "tame" and refuses to smooth down no matter what, has a discernible curl pattern when wet without product. My edges are short and curl very easily. But they are not a silky texture and when dry look to be 4Bish, although I knew that they did not seem to fit the bill for 4B, I couldn't figure out what they were. When dry they are frizzy and it's hard to see a curl pattern at all. With gel they wave but when the gel dries they are just dry looking curls that from a distance just look like dry fuzz. The rest of my new growth is coils that vary in size, dry when stretched into a clear S shape, and it's very frizzy. When wet they seem so dense that you cannot see the curl pattern until you stretch the hair with your fingers.
The most useful part of the article to me was the description of hair texture and thickness. I learned that I have coarse hair and medium thickness. I never knew I had coarse hair - I knew it wasn't fine but I didn't realize it was coarse. The individual strands feel like silk and overall my hair has always been very soft. So that to me was fascinating.
There's more to hair typing than the type of curl my hair has. So instead of hair typing I think I'll call the whole type 1-4, C-Napp thing "curl typing".
And I give up on that!
