Hair can be classified according to the oil distribution of the strands as normal, dry, oily or mixed, and it is important to identify the type so that the most suitable products can be chosen to care for the hair correctly, keeping it shiny and soft.
The shape and structure of the thread can vary according to ethnic origin, because these characteristics are related to the chemical and molecular composition of the threads, so they can be classified into three large groups:
- Orientalwhich has a straight edge;
- Caucasianwhose hair can vary from wavy to curly;
- Afroin which the strand is flatter, so that it tends to be curlier.
Thus, depending on the amount of chemical bonds that exist in the strand, also known as disulfide bonds, the hair can be more or less curled. In other words, the more disulfide bonds present in the strand, the more coiled the hair can be.
