What makes curly hair curly?

Rollers and braids? haha... I'm actually wondering why hair is naturally straight or wavy or curly.



What makes curly hair curly?

The amount of natural curl in a hair depends on the shape of the hair follicles. Straight hair grows from a follicle that is more or less round, and the hair itself is round in cross section. Wavy hair is kidney-shaped in cross section, and the amount of wave in the hair depends on the degree of curve in the follicle. Curly hair grows from a very curved hair follicle.



I had to teach this in a high school anatomy class.

Scientists believe that hair is either curly or straight, depending upon the number of disulfide bonds between hair proteins found in the hair shaft. The idea is that the greater the number of links between sulfur atoms, the curlier the hair, conversely, the fewer the number of links, the straighter the hair.

Straight hair has a round cross section. Curly hair has an oval shaped cross section. The flatter the oval the curlier it is.
