Transcript of the clasifications of hair color two
of Hair Color But First!! To understand hair color first you need to understand the structure of the hair. The outermost layer is the cuticle; this layer is made of flat scale-like cells to protect the inner layers. The second layer; the cortex gives the hair is strength and elasticity. This layer is made of fibers twisted together like a rope. Then there is the innermost layer; the medulla made of soft keratin. The medulla is often not present, and has no effect on the hair itself
When the color uses an activator the cuticle flares out to let molecules lay between them. But if forced to much the cuticle becomes damaged.
Temporary semi-permanent demi-parmanent permanent Temporary color sits on the outside of the cuticle and adds color to the surface of the hair. Temporary hair color won't take you from a darker shade to a lighter shade, but it can add some depth and richness to lighter hair. Temporary colors rarely last beyond your next shampoo.
Temporary Hair Color molecules are large in size compared to other hair color molecules.
Temporary color is great for special events; when you want bright colors.
Semi-permanent hair color adds color without changing natural color dramatically. The hair color contains tiny color molecules that enter the hair's cuticle, or outer layer, and go into your hair's cortex. They don't interact with your natural pigments. And since the molecules are small, they eventually exit the hair shaft after several shampoos, leaving the hair as it was before treatment. This level generally lasts for 6 to 12 shampoos, covers up to 50 percent gray, enhances your natural color and leaves no roots. This hair coloring won't lighten your hair color because it contains no ammonia or peroxide. This product level lasts longer, through 24 to 26 shampoos. In this process, pre-color molecules penetrate the cuticle and enter the cortex where they then partner to create medium-sized color molecules. Their larger size means they take longer to wash out. These products do not contain ammonia so the natural pigment can't be lightened. However, it contains a small amount of peroxide, which allows for a subtle, but noticeable, color enhancement. It also blends and covers gray. This is what you need for a more significant color change. At this level, both ammonia and peroxide are used. Tiny molecules enter all the way into the cortex, where they react and expand to a size that cannot be washed out. Your hair actually has to grow out over time.
This product acts to lighten the hair's natural pigment to form a new base and then to add a new permanent color. The end result is a combination of your natural hair pigment and the new shade you chose. That means the color may appear different on you than on someone else using the same color. Regular touch-ups of 4 to 6 weeks are generally needed to eliminate roots.
