- Dyes are formulated to give hair
long-lasting and richly hued colors, but several factors — from
mechanical to environmental — can accelerate color changes and
fading.
- In general, hair dyes include dyes,
modifiers, antioxidents, alkalizers, soaps, ammonia, wetting agents,
fragrance, and a variety of other chemicals used in small amounts that
impart special qualities to hair (such as softening the texture) or give
a desired action to the dye (such as making it more or less
permanent).
- The four most common classifications of
hair colouring are permanent, demi-permanent (sometimes called deposit
only), semi-permanent, and temporary
- The first commercial hair-coloring
product was invented by Eugene Schuller in 1909.
- In the recent years, the demand for
hair dye has been increasing. More and more people are concerned with
the color of their hair, whether it is to hide gray hair or to
experiment with new colors.
- Other chemicals used in hair dyes act
as modifiers, which stabilize the dye pigments or otherwise act to
modify the shade.
- Most permanent hair colouring
technology uses a 150-year-old approach that uses p-phenylenediamine
(PPD), a chemical that produces darker,
browner shades when exposed
to air
- A great majority of the dyes used in
hair colouring are known as oxidation hair dyes.
- Oxidation dyes, the more permanent of
the two groups, are produced directly on the hair by oxidizing aromatic
diamines such as para-phenylenediamine or 2,5-diaminotoluene with an
oxidizing agent.
- New understandings in genetics and
biology and the role of DNA in dictating the color, condition and health
of hair are taking hair-coloring technology into a whole new
realm.
- Scientists are looking into
hair-coloring techniques of the future, including nano-sized colorants
and substances that stimulate the genes to produce melanin pigment that
colors hair
- New discoveries in hair biology and
coloring chemistry have led to significant advances in hair coloring
products and possibilities, reducing
the trade-o s in hair health.
- Extensive studies have concluded that
hair colorants are safe when used as directed and pose no health risk to
pregnant women, unborn babies or infants.
