Despite all those differences, they have one thing in common: They are all great and something to be proud of!
1. Who is in what form?
If you cut a hair in half and put it under the microscope you would see that straight hair is really around. The shape of her hair is somewhat more oval. The flatter the shape of the hair, the more it curls. Curls, therefore, have an elliptical shape: a flat oval. And Kinky hair is the flattest, making your curl pattern look like Z-ties.
2. Who has the most dominant genes?
Hair shape is determined by a gene pair. 1 allele you get from your father, 1 from your mother and that mix would determine whether you get curls or not.
Curls are known to be dominant and straight hair is recessive. So if your gene pair consists of 1 curl allele and 1 straight hair allele, then you should get curly hair. Not quite. Curls would not simply be dominant, but incompletely dominant. That means that you get a haircut with a genetic mix of curls and straight hair.
Here and there some questions about this theory are put. It seems to be a bit more complicated than it is said and it would not explain everything at all. I also wonder, for example, what the situation is with different types of curls because one curl is not the other. And why, as a child, you can have curly hair and later get straight hair. And, yes, questions keep coming, what about the fact that you can have both curly and steep hairs on your head at the same time?
All in all, a lot of research is being done and scientists are well on their way to determining the precise genes that are responsible for curls, blow and straight hair. So is undoubtedly continued.
3. Who has the most hair?
You wouldn’t say it in terms of volume, but on average, straight-haired people have more hair than curls. If you have straight hair you would have around 120,000 hairs on average and if you have curls you should do it with 20,000 fewer. But other things also play a role in how much hair you have, for example, your hair color, your origin, and your health.
4. Who suffers from tangles the fastest?
It might surprise you, but recent research shows that straight hair really does stick faster than curly hair. Yes, you read that right. And no, I am not saying that wrong. Straight hair tangles faster. This would be because curls move more together as a whole, and therefore do not get in each other’s way as quickly as straight hairs, which behave like loose individual hairs. Steep hairs, therefore, do everything they feel like and therefore collide much more with each other, while curly hairs do teamwork instead of colliding. Little was said about stroke in the study.
Tangles occur when the scales of your hair hook into each other and especially the angle (how many degrees) in which the hair collides is very important here. But scientists also say that it is not the shape of your hair that is most important in creating tangles, but that fine hair, dry hair, and especially damaged hair have the most tangles because of the scales that are raised or broken off.
5. Who is the fastest fat?
Straight hair becomes greasy much faster than curly hair. This is mainly because sebum (your own skin oil) spreads much more easily over straight hair: it is one straight path down and the open round shape of the follicle ensures that the sebum is evenly distributed evenly from your roots over the hair.
In the Curly Girl book, I also read the claim that you would have fewer sebaceous glands if you have curls because you often have less hair. To what extent this is correct I could not really find it in scientific studies.
6. Who can dry comb best and who can wet?
Wet hair is weaker, that’s a fact. When you have curled it is better to comb your hair when it is wet. This has to do with resistance. If you have curls, I don’t have to tell you how difficult it is often to come through dry with a comb. It is, therefore, better to comb it (preferably with your fingers) while your hair is wet and has a conditioner. This way you reduce the resistance and do not disturb your curls. That way you prevent frizz and a lot of damage to your hair.
