level<\/dfn><\/dt>\n
\n

The darkness or lightness of colour in relationship to other colours.<\/p>\n<\/dd>\n

line of demarcation<\/dfn><\/dt>\n
\n

The line where the natural regrowth meets the previously coloured hair.<\/p>\n<\/dd>\n

medulla<\/dfn><\/dt>\n
\n

The inner core of a hair strand, which gives hair its structure. Often missing from very fine hair.<\/p>\n<\/dd>\n

melanin<\/dfn><\/dt>\n
\n

Pigment that resides in the hair's cortex which gives hair its hue.<\/p>\n<\/dd>\n

neutral<\/dfn><\/dt>\n

neutralize<\/dfn><\/dt>\n
\n

To counteract or drab the intensity or hue of a colour.<\/p>\n<\/dd>\n

non-oxidative colour<\/dfn><\/dt>\n
\n

Colouring products that do not require the use or mixing of a developing agent such as hydrogen peroxide.<\/p>\n<\/dd>\n

oxidation<\/dfn><\/dt>\n

The process in which a developing agent combines with an oxidative colouring product to turn colourless molecules into coloured molecules for the purpose of hair colouring.<\/p>\n<\/dd>\n

oxidative colour<\/dfn><\/dt>\n
