Why, why do we battle brassiness?
To understand brassiness, we must understand Natural Contributing Pigment (NCP).
Natural contributing pigment is the varying degree of warmth exposed during the lightening process.
Natural pigment is the pigment which remains in the hair after lightening or applying colour. These pigments contribute to the final colour result.
When lightening hair colour, the natural hair colour goes through various lifting stages.
As hair lightens, melanin is removed in order of the size of the molecule, which ranges from darkest to lightest, and as a result the underlying tones are exposed. The brassy/reddish/yellow colours are the largest colour pigments, and the most difficult colour pigment to remove, which is why all colour always gets warmer when it is lightened.
The natural pigment left in the hair at the desired level is referred to as Natural Contributing Pigment (NCP).
As all NCP is warm, typically the best option to manage unwanted warmth is to select a cool colour which will neutralise warmth.
Understanding and accounting for NCP is critical in correct colour selection for colouring.
NCP is one of the most important factors to consider to ensure a successful colour outcome.
Pleasantly surprised by this product. Normally non-toxic hair dyes leave my hair totally brassy and this is the 1st one that gave me a great colour and covered my greys as well. So well done – great product!R. Donnelly
The colour is excellent, and true to the images on the website, not brassy at all and I have a lot of red pigment in my hair naturally.K. Ndaira
