Depth: Darkness or shadows in hair color that gives the hair contrast.

Developer: Oxidizing agent, that when mixed with ammonia, will allow the color to penetrate through the cuticle layer.

Development Time or Oxidation period: Time it takes for color to lift cuticle and deposit color.

Diffused: When the concentration is diluted. Visually dispersed, not limited to one area of the hair.

Direct dye: Type of color that will stain the cuticle and does not require oxidation. 

Discoloration: Loss of pigment or color.

Double process: Two chemical processes in a single service time i.e. root touch-up and highlights.

Drab: Describes hair color that lacks warmth (Red and Gold).

Dull: Lack-luster, lacks shine or vibrancy.

Dye: Generic term used for artificial color. 

 

Elasticity: Measures the amount of stretch or buoyancy the hair has before it will snap.

Enzyme: a protein that kick starts a chemical process.

 

Fade: Loss of artificial color over a period of time.

Fillers: Adding artificial color in place of natural pigment when going darker.

Formulas: The specific code of color used when performing a color service.

 

Hair Color: Artificial or natural pigment and tone of the hair.

Hair Root: where the bulb of the hair strand lives.

Hair shaft: the strand of hair that contains the cuticle, cortex, and medulla layer.

Opaque: The amount of light that can shine through.

Outgrowth: Same as new growth.

Overlap: Layering color or lightener onto previously processed hair.

Oxidation: Oxygen causes the start of a chemical reaction.

Oxidative hair color: Hair color that will continue to lose strength the longer it is exposed to oxygen.

 

Para tint: Oxidative dyes that make a color.

Patch test: Testing for skin reactions before beginning a new chemical service.

Penetrating hair color: Hair color that penetrates the cortex and sits in the cuticle layer.

Permanent hair color: Hair color that penetrates the cortex and sits in the cuticle layer permanently.

Peroxide residue: Peroxide that gets left in hair following a lightening service.

Persulfate: Used in developers and activators to accelerate the lifting process.

pH: Measurement of the acidity or alkalinity of hair color.

Pheomelanin: Gives hair red, yellow pigment.

Pigment: Describes the specific colors seen in hair.

Porosity: How open or closed the cuticle layer sits to measure absorbance. 

Powder Lightener: Type of lightener that must be mixed with the developer to activate.

Pre-lighten or Pre-bleach: Lifting hair before you deposit a color.

Primary Color: Red, Blue, Yellow are the primary colors that make up all other colors.

Processing Time: The amount of time it takes a chemical reaction to complete.

Progressive Dye: Does not lose absorption or depositing strength with time.
