I suppose I'm just one of those people that just doesn't see what's so hard about hair typing.
If your hair's straight with no bend or wave, you're a type 1. If it's baby fine and thin, it's an A, medium with good body a B, and if it's coarse, slightly wiry and thick it's a C. If your hair isn't straight when it's wet and dry; it's not a type 1.
If you've got a bit of a wave but not much it's a 2a. If you've got bigger waves it's a 2b and if the waves are almost a curl, it's a 2c. If you hair looks straight when it's wet but waves up when it's dry, you're a type 2.
If you have big curls and it's easy to get your hair to look wavy, it's a 3a. If those curls are spirally, medium sized O shaped or S shaped and are bigger than a coffee stirrer, it's a 3b. Andre doesn't have a 3c so in his book 3c's are 3b's but if your curls are the size of a coffee stirrer to a pencil, very defined and look much longer wet, it would be what naturally curly calls a 3c. If you hair looks either very wavy to curly when it's wet and the curls get tighter and more defined when it's dry, you're a type 3.
If you have defined curls that are very small and tend to lose that definition when they dry and have a lot of shrinkage in it's natural state, it's a 4a. If there's no curl definition or it's very minimal and there's also high shrinkage, it's a 4b. If your hair looks curlier wet than dry and shrinks up more once dry, you're a type 4.
If you chemically alter your hair, you need at least an inch of new growth to determine what your actual natural hair type is. The more natural hair you have, the clearer it is to tell.
Somewhere along those descriptions, your hair is going to fit in. It won't always be a perfect match; it may not describe every hair on your head but you can have a general idea of what kind of hair you have, if it really matters to you.
