The different types of hair color

 

In previous posts we talked  about the fear of hair color on relaxed hair, now I am going to talk about the different types of hair color so that you will have a better understanding.

TEMPORARY
Temporary colors, as the name implies, are used to create temporary color changes that last from shampoo to shampoo.  They are non-reactive, direct dyes, which means no chemicals re needed to develop them.  There's nothing in the product that will lighten the hair and no chemical changes occur in the solution or in the hair.

SEMI-PERMANENT
Semi-permanent colors use a direct dye process.  Direct-dye colors do not need mixing and the color you see in the bottle is the color that will be deposited on the hair.   Since these colors do not use chemicals to alter the hair, they can only deposit color and cannot lighten the hair.  These colors generally last for several shampoos.

DEMI PERMANENT (Long lasting semi permanent)
Demi permanent color uses a low volume peroxide to develop the color molecules and aid in the color process.  These products contain very little or no ammonia and are designed to deposit color or add tone to the hair.  They are not designed to lift or lighten the existing hair color and they generally last 4 to 6 weeks.

PERMANENT
Permanent hair colors are mixed with hydrogen peroxide and are capable of both lifting natural pigment and depositing artificial pigment in one process.  They are sometimes referred to as "oxidative tints" that utilize ammonia.   It is the combination of the ammonia in permanent hair colors and hydrogen peroxide that allow for the lift and lightening of the hair's natural color.

In order to maintain healthy hair with any type of color it is best if you seek out the advice as well as the service of a licensed cosmetologist.
