Hair is composed of 3 principal parts: Cuticle:outer coating composed of overlapping scales Cortex:protein rich structure around the medulla that contains pigment Medulla:central core (may be absent)

The word "hair" usually refers to two distinct structures: the part beneath the skin, called the hair follicle. This organ is located in the dermis and maintains stem cells, which not only re-grow the hair after it falls out, but also are recruited to regrow skin after a wound. the shaft, which is the hard filamentous part that extends above the skin surface.

Facts about hair… Hair is composed of the protein keratin, which is also the primary component of finger and toe nails Hair colour is mostly the result of pigments, which are chemical compounds that reflect certain wavelengths of visible light Humans develop hair follicles during fetal development and no new follicles are produced after birth Gray hair occurs when melanin production decreases or stops

Shampoos and conditioners tend to penetrate through the channels between cuticle layers and then through the junction of cuticle layers and the cortex.

Colours… All natural hair colours are the result of two types of hair pigments. Both of these pigments are melanin types, produced inside the hair follicle. Melanin is the dominant pigment in brown hair, and black hair, while pheomelanin is dominant in red hair. Blond hair is the result of having little pigmentation in the hair.
