Hair colors are soluble substances or  liquid preparations used for staining, highlighting or tinting hairs.  Different hair colors added or subtracted from the normal hair color  gives various hues and shades.
A  French chemist Eugene Scheuller created the first hair coloring in  1909, based on a chemical called paraphenylenediamine. Hydrogen peroxide  and ammonia are the main ingredients of any hair-coloring agents.  Hydrogen peroxide creates a color that lasts long and ammonia when  combined with hydrogen peroxide allows the color to permeate into the  cortex.
Selecting  the best shade or highlights depends on various factors. It completely  depends on facial shape, complexion, haircut, facial expression, eye  color, hair length, as well as personal taste. These colors can be  various shades and intensity. Depending on intensity or tone colors can  be warm or cool. Warm tones are shades of oranges, reds and yellows and  cool tones are shades of blues, violets and greens. People who are cool  should not use warm tones because that might lower down their features.  The best shades for cool people are purple orchid hues, burgundy and  lipstick red.
People  who are warm by nature should preferably use simple gold highlights and  golden blondes. Cool tones suit the people with olive complexion and a  medium complexion with no pink to a faint pink at the cheeks. Warm skin  types include individuals with medium brown skin with pink or gold  undertones. Selecting a warm or cool tone also depends on the eye color.
