DID YOU KNOW

One kilowatt-hour will power a television for three hours, run a 100-watt bulb for twelve hours, and keep an electric clock ticking for three months.

(FYI - that was directly quoted from the textbook Milady 2012)

The Nature of Electricity

2

and the

2 Types

of Electric Current

#1

Direct Current (DC)

Is a constant,

even-flowing current that travels in

one direction only and is produced by

chemical means.

Flashlights, mobile

telephones, and cordless hairstyling

tools use the direct current produced by

batteries.

#2

Alternating Current (AC)

is a rapid and interrupted current, flowing first in one direction and then in the opposite direction; it is produced by mechanical means and changes directions 60 times per second.

Corded hair dryers, curling irons, electric files, and table lamps that plug into a wall outlet use alternating current.

Electrical Equipment Safety

3

FUSE

prevents excessive current from passing through a circuit. it is designed to blow out or melt when the wire becomes too hot from overloading the circuit with too much current

CIRCUIT BREAKER

is a switch that automatically interrupts or shuts off an electric circuit at the first indication of
an overload

GROUNDING

completes an electric circuit and carries the current safely away.

used in cosmetology

Galvanic Current

(named after Luigi Galvani) constant and direct current that provide services like Iontophoresis, Cataphoresis, Anaphoresis, and Desincrustation.

Microcurrent

extremely low level of electricity that mirrors the body’s natural electrical impulses.

iontophoresis, firming, toning, and soothing skin. it also can help heal inflamed tissue, such as acne. when used for aging-skin treatments, results give a softer, firmer, more hydrated appearance.

Tesla high-frequency current

(named after Nikola Tesla) also known as violet ray, is a thermal or heat-producing current with a high rate of oscillation or vibration that is commonly used for scalp and facial treatments.

LIGHT

and its majestic qualities

Light Energy & Therapy

Visible Spectrum of Light

makes up 35% of what natural sunlight lets us see

Invisible Light

ultraviolet (UV) short wavelength (high energy) 3 types, UVA, UVB, UVC and infrared … longer wavelengths, penetrates more deeply, has less energy, and produces more heat than visible light.

Heat & Energy

Catalysts are substances that speed up chemical reactions. Some catalysts use heat as an energy source while others use light. Whatever the energy source, catalysts absorb energy like a battery. At the appropriate time, they pass this energy to the initiator and the reaction begins.

Light Therapy

also known as phototherapy, is the application of light rays to the skin for the treatment of wrinkles, capillaries, pigmentation, or hair removal.

Laser

an acronym for

Light Amplification Stimulation Emission of Radiation;

it is a medical device that uses electromagnetic radiation for hair removal and skin treatments

LED

Light-Emitting Diode:

a medical device used to reduce acne, increase skin circulation, and improve the collagen content in the skin.

Intense Pulse Light

a medical device that uses multiple colors and wavelengths (broad spectrum) of focused light to treat spider veins, hyperpigmentation, rosacea and redness, wrinkles, enlarged hair follicles and pores, and excessive hair.
