INFORMATION AND HAIR BIOLOGY
Our hair consists of a three-layered hard protein structure. The inner layer is called the medulla, while the second layer is known as the cortex. Together, these two layers also determine our hair colour. The outer layer consists of scales that overlap like roof tiles.
Hair follicles are formed in the womb and are fully grown by the 22nd week of gestation. Our bodies are covered with 5 million of these follicles. This is the maximum number, since the body does not produce new follicles. There are approximately 90,000 follicles on a fully-haired scalp. Hair colour affects this number, with redheads having around 100,000, brunettes 110,000 and blondes 140,000.
A follicle is a tunnel-like skin component. At its base are small veins that nourish the follicle. It also has a hair muscle. When this muscle contracts, your hair stands on-end and sebum is released. This substance is produced by the sebaceous gland and is essential for keeping our hair in good condition.
Hair growth cycle
Unlike other mammals, our hair grows and falls out regardless of season. The following cycle applies to human hair growth:
What we’ve found out about the hair growth cycle has yielded us important information. Information that we’ve used in our quest for a remedy that prevents androgen hair loss and supports normal hair growth. We’ve discovered that:
