Hair development

At the bottom, hair bulb connects to hair papilla which are made of dermal cell. All nutritions and oxygen are delivered from hair papilla to hair bulb through blood capillary, and it creates hair matrix cells. When hair matrix cells grow and divide cells, hair develops upper and upper as cornifying. Accelerating blood circulation of blood capillary is one of key to develop hair properly. Hair is mainly made with keratine, a genetic name of protine made with combination of 18 types amino acides. To accelerate hair growth, it is important to consume good protines, vitamins and minerals at the same tine.

Length of Anagen stage differs between men and women. For men, it is for 2-5 years and 4-6years for women. After Anagen stage, 1-1.5months for Degeneration stage, and 4-5months for Teolen stage. After 4-5months of Teolen stage, hair falls automatically. At the end of Teolen stage, new hair starts to grow.
