What you need to know before using a hair dye
If you have decided to purchase a DIY hair dye, i.e. an at-home product, you should be aware of various things.
One of the main things to evaluate is your choice of colour which should take into consideration your natural hair colour.
Hair colours are identified by a number on the box that corresponds to the level of colour: based on an international colour chart, the shades are arranged on a scale in which number 1 is BLACK and 10 is LIGHTEST BLOND.
It is crucial that you have an idea of your natural hair colour because you can choose your colour from a range that includes a few tones above it, and go darker, yet only one tone below, and go lighter. Let us give you an example: if your natural hair colour is a 7, i.e. BLOND, you could also choose a very dark colour, from 6 all the way down to include even black, however you can only “go up”, i.e. lighten, your hair by one tone, meaning a number 8 colour, which is LIGHT BLOND.
This issue of the numbers becomes more complicated because there is often a second and, at times, a third number alongside the first: these numbers indicate the reflect colour, which are the primary and secondary reflect colours respectively, and for this we also refer to the international chart.
For example, an 8.3 is GOLDEN LIGHT BLOND.
Another important thing you should know is that the colour shades are developed by formulators together with expert hair technicians, with initial tests of locks of hair and then on the heads of actual models, however the end result of the colour also depends on many variables related to the structure of our hair: finer or thicker, perhaps a little more porous, with a damaged cuticle, etc.
