Underlying Pigment Underlying Pigment, also known as Remaining Pigment Contribution (RPC), is crucial during color formulation. It refers to the remaining pigment exposed at the level that you have lifted the hair to during the lightening process. The chart below shows how the color wheel helps us understand the Underlying Pigment and formulate the level of lift and corrective neutralizing tone. This will give you the best prediction of how a chosen color will interact with the existing pigments.
The pH scale measures the acidity or alkalinity of a solution and plays a significant role in the hair coloring process. It ranges from 0 to 14, with solutions below 7 being acidic and those above a pH of 7 being alkaline (basic). A pH of 7 is considered neutral. The pH of hair and skin is slightly acidic, ranging from 4.5 to 5.5. Hair Color products contain alkaline solutions which swell the hair strand, allowing the cuticle to open and color molecules to penetrate.
