Hair and hair growth
The strength and characteristics of hair growth are primarily ethnically (ancestral) determined and inherited. The quality, quantity, shape and color of the hair are closely related to the type and age of the person (hormonal). The reasons why head and body hair can change over the course of a person’s life have not yet been fully researched. Human hair is a complex structure consisting mainly of various horny substances (keratin). These horn substances are similar to those found in fingernails. They are made up of poorly soluble, sulfur-containing, mostly fibrous raw materials. (Note: This indicates how aggressive depilatory creams need to be in order to achieve their goal).
