It works like protective scales. Each cuticle cell is composed of several different layers such as A-layer, exocuticle, and endocuticle. It is resistant to chemicals and protects the cortex from chemical influences.The cortex is where moisture and natural pigment (called "melanin") are held. No other part of the hair shaft has pigments. Melanin contained in the cortex determines the natural color of your hair. Some hair color products, especially when lightening hair, work on melanin. Melanin is missing from gray hair.The medulla is the core of the hair shaft. Sometimes the medulla is absent from hair, and it's not yet scientifically clear why this happens.The cuticle, the outer layer of the hair shaft, defines smoothness and shininess - because it can be seen and touched. Hair (cuticle) may get damaged by chemical processes, overexposure to sunlight (UV), too much heat from a dryer, abusive brushing and combing, over-chlorinated swimming pool water, etc.Damaged hair/cuticle should be treated well with conditioners because the cuticle cannot repair by itself once it is damaged.Hair type and coloring result in tendency.Just like fingerprints, hair type is unique to each individual. We have soft, medium, hard, thick, coarse, straight, curled, damaged, and colored hair - with numerous combinations of all of the above Also, natural (original) hair color and level of brightness (which is determined by melanin) vary greatly. There are black, brunette, red, blonde, and variations within each. Even when it comes to black hair color, their many variations.Your coloring result is influenced by hair type and beginning color. If your hair is fine and soft, and your natural color is light, then it is more likely to be influenced by chemical actions and will color stronger than expected. If your hair is hard and thick, and your natural color is dark, then it is less likely to be influenced by chemical actions and will color weaker than expected.In addition, the color tends to deposit more strongly initially, then fades away more quickly onto damaged or color-treated hair. Virgin hair is more resistant to coloring.Basic Tips to Color Successfully.These tips are all included on the instruction sheet, please go through the website for details.Do a strand test before application to see the coloring result and check the appropriate processing time in advance - because all hair is different Apply the mixture on hair that is dry, free from styling build-up, and not colored with metallic dyes, henna, or color restorers.
