My last Question would be why does my blonde hair look lighter in
daylight? Daylight is the ultimate white light because it has such a huge
energy source (The Sun). We have all said to a client take the mirror out
into the daylight and you will see the true colour.
Light in the salon usually comes from 100 what bulbs. The light
transmitted from 100-watt bulbs is very warm, because it only contains
two wavelengths, visible red and invisible infrared wavelengths.
Everything this light touch reflects very warm in colour, therefore making
white blonde hair look yellow.
Some salons have only fluorescent lighting. This form of white light is
created by filling and sealing a glass tube with mercury vapour, when the
mercury vapour is electrically charged it emits ultraviolet wave lengths
only, which are absorbed by the coating of phosphors on the inside of the
glass tube, converting and emitting mainly green wavelengths along with
some red and blue as well.
