髮理基本篇(1)

Our hair scalp has 100,000-350,000 follicles in which our hair is grown.   Each follicale has veins around to provide sufficient nutrient.

Hair is grown in 3 parts :

1. Cuticle, composed of 5-10 layers, protects the inner construction.   If cuticle is damaged, the inner construction will be exposed which results in dehydration and dull looking hair.

2.  Cortex is the inner construction with protein chain and other nutrients for controlling the hair color, elasticity and softness.

3. Medulla is the most inner part of hair and normally be found in healthy hair.   It enhances shininess of hair color with natural light reflection.

Asian generally have 100,000 hair strands, with daily growth at 0.3-0.4cm and hence each month has about 1.25cm hair growth.
