Type 3A is a loose spiral curl without a lot of shrinkage. (We're using this term figuratively. Shinkage only happens to biological human hair. As hair dries or loses moisture, each strand contracts. This is called "shrinkage," and it is what makes naturally curly human hair coil to form a curl.)These are relatively large curls with a loop that can fit around a big piece of sidewalk chalk. Pay particularly close attention to where on the hair shaft the curls begin. Some will begin up at the "root", while others may be straighter on top and start to curl midway down the hair shaft.
