Hair pieces is divided into 3 kinds level of tissue :
Kutikel (the outer tissue that look a like fish scale that protect all the hair). Korteks ( the second level of tissue). Medulla ( the core of hair). Healthy hair have enough kutikel that close very well (unbreak) that’s why the hair reflect the light and look shiny.
Every pieces of hair have an oil gland at its hair roots to protect the kutikel and keep it soft. But the kutikel can be broken by polution, hot weather, hair paint, hair dryer, water that contain klorin and metal material, or hair treatment product that didn’t suit to the head skin. If the kutikel is broken, the inside part also can be broken and cause branching on the top of the hair.
Kutikel is a thin tissue that didn’t have colour and protect the korteks.
Korteks, tissue inside the hair, decide the strength, elasticity, thickness and hair teksture. Curly, straight, crisp hair was influence by the korteks. Beside that, korteks contain melanin which is the pigmen that give colour to our hair.
Medulla or hair core has the shape like a sponge that decide the diameter size of hair and reflect the hair colour. As the movement of our age the condition of the medulla is decreasing hair colour.
