How Does Hair Dye Work
First an alkaline chemical plus two types of particles that will come together to form the new color.
How does hair dye work. Hair dye doesn t just rinse across your hair and stain it. Opening up the cuticle the overlapping cuticle scales need to be lifted so the chemicals in the dye can get to the cortex. When you wash your hair it should rinse right off.
Keeping your hair moisturized keeps that cuticle sealed thus the hair retains the dye longer. Bleaching the hair to help the new colour show up more prominently hydrogen peroxide is used to bleach the hair making it lighter. With this type of hair dye ammonia and peroxide are used.
Semi permanent hair dye is one step more permanent than temporary. Temporary hair color. Permanent hair color is the right decision for someone wanting to make a significant color change.
Ammonia is an alkaline chemical that helps open up the hair shaft for the color to be deposited on the hair. Permanent dye as the name suggests is designed to stay with your hair until the hair grows or falls out. It improves the organic colouring of your hair but does not reduce it as a result of reality that it contains number ammonia or peroxide.
Dye precursors and dye couplers. In general permanent dye consists of two solutions. It is a good idea to condition any time you wash your hair and deep condition once a week paying special attention to the last 1 3 inches at your ends where breakage and dryness is most likely to occur.
This is done using an alkaline chemical usually ammonia the mixed hair dye is usually at a ph of around 10. Temporary or semi permanent hair colors may deposit acidic dyes onto the outside of the hair shaft or may consist of small pigment molecules that can slip inside the hair shaft using a small amount of peroxide or none at all. The role of ammonia in hair dye is to create the perfect ph necessary to open the cuticles and actually allow the hair dye to penetrate into the cortex where natural pigment is lightened and artificial color is deposited.
