Back to Basics: Artificial Color Pigments

Developed Pigments

All semi-permanent hair colors contain developed pigments. Demi-permanent colors contain a mix of developed pigments and un-developed color precursors (small-uncolored molecules that penetrate deep into the hair before merging into big color molecules, also known as polymerization).

Note that a permanent color has a high percentage of color precursor for longer retention of color in hair.

What are the Characteristics of Semi-Permanent Products Containing Direct Dye Pigments?

• They are ready for use and do not needoxidationor developer lotion
• The coloring process does not affect the structure of the hair
• The color fades gradually no need for retouching unless this is desired
• The product can be pH-neutral to weak acid and therefore will not damage the hair
• The natural pigments already present in the hair will influence the final shade

What are the Characteristics of Permanent-Color Products Containing Color Precursors?

• They need oxidation or developer lotion
• Development time is needed
• Before oxidation color precursors are colorless, dissolved salt crystals
• They use oxygen provided by developer lotion to form yellow, red or blue pigments
• Polymerization makes them develop into bigger particles inside thecortexof the hair
• This delivers great durability because the precursors grow into the pigment and settle themselves inside the hair structure
• These new developed artificial pigments are combined in different quantities making a huge range of potential target colors possible
• They are not transparent and have the ability to cover natural white hair
