Naturally Curly Hair Growth Prediction/Theory

It should come as no surprise that I examine my hair very often. It's still something new to me so I try to learn as much about it as I possibly can. So, every now and then when I'm bored, I'll sit in front of my mirror with an index card and put it behind my hair to examine it piece by piece. I also study photos of curly hair that I come across in every day life.

These examinations have caused me to come up with a theory about my hair, that can be applied to curly hair in general, concerning the way curl units grow. In the very front/top of my hair, there is almost no curl definition. The hair there is just wavy with no real units forming until you get to the very end of the strands. After about the first four to five inches, the hair no longer waves and starts to curl all in the same pattern, and become a defined, visible curl.

I've seen this on all kinds of curly hair, not just highly textured African-American natural hair. So, that lead me to the conclusion that some hair has to reach a certain age before it begins to grow in the same pattern as the hairs around it and form a defined unit.

Hair grows from the scalp at about half an inch per month, so the ends of our hair are the oldest parts and hair closest to the scalp is the youngest. If I have 5.5" of hair, and the first 5" has grown in random waves and the last half inch all comes together in the same curl pattern, that tells me my hair has to be at least eleven months old for it to grow in the same pattern as the hair around it and become a true unit. So, the first 5" of my hair might always be randomly wavy, but if my theory is correct, all hair after that will be in actual curl units.

What do you guys think? Let me know in the comments. Later, loves. :-*
