How to drape for a chemical service?
Sanitize hands
neckstrip
towel-cape-towel
is the tough, outer protective covering. This layer is generally made of 7 to 12 layers of transparent, overlapping scale-like (flat) cells. How tightly the cells overlap determines how quickly product will be absorbed into the hair.
Cuticle
The medical term for gray hair
Canities
the three basic starting colors from which all other colors are produced. They cannot be created by mixing any other colors together.
Primary Colors
negatively charged particles that revolve around the nucleus on orbiting paths and are involved in chemical bonding with other atoms.
Electrons
determines if an individual is allergic to haircolor products containing
aniline derivative dye molecules.
Predisposition Test, also known as Patch Test
is the soft, elastic, thick, inner layer made up of elongated cells that bond together tightly. This fibrous layer contains the coloring matter (melanin) and the hair’s protein (keratin).
It is responsible for an estimated 90% of the hair’s weight.
Cortex
a stable mixture of two or more substances,
which may be solids, liquids, gases, or a combination
of these.
Solutions
the science that deals with the composition, structures, and properties of matter and how matter changes under different chemical conditions.
Chemistry
are atoms containing an excess amount of electrons or not enough electrons in their orbiting paths.
Ions
is the warm
or cool tones seen within the predominant haircolor.
Undertone, also known as Contributing Pigment
is the deepest layer, consisting of round cells. Sometimes it is intermittent or totally absent. This is known to not have any true effect on the hair. Haircolor does not reach this layer.
Medulla
increases the porosity of the hair, opening the cuticle, allowing for
more pigment to be absorbed.
Presoftening
the chemical reaction that occurs when oxygen is released
from a substance.
Oxidation
is created when one or more atoms combine and retain their chemical and physical properties to form matter.
Molecule
will determine if the haircolor is absorbing and processing evenly.
Processing Strand Test, also known as Periodic Strand Test
the coloring matter that provides natural color to our hair, skin, and eyes.
Melanin
is the simplest form of matter. It cannot be broken down into a simpler substance.
Element
studies substances that do not contain carbon and are not living or alive.
Inorganic Chemistry
an organic compound of colorless gas with a strong, pungent odor, composed of nitrogen and hydrogen.
Ammonia
the next step in the haircolor process. It is a safety precaution to avoid excessive damage to the hair and ensure your Guest’s satisfaction prior to delivering the entire service.
Preliminary Strand Test
What are the two types of melanin
Eumelanin produces brown to black pigments in the hair.
Pheomelanin produces yellow to red pigments in the hair.
an oxidizing agent that when mixed with haircolor and/or lightener creates oxidation-reduction.
Developer, also known as Hydrogen Peroxide or Catalyst
the rapid oxidation of any substance, accompanied
by the production of heat and light.
Combustion
matter that is made up of the same type of particle throughout and have a definite chemical and physical property.
