Understanding Electricity
A constant, even-flowing current that travels in one direction and is produced by chemical means.
What is alternating current?
Prevents excessive current from passing through a circuit.
What is a fuse?
The currents used in electrical facial and scalp treatments
What is modalities?
Sources of dry heat that can be used to shorten chemical processing time
What are hood dryers or heat lamps
The distance between successive peaks of electromagnetic waves
What is a wavelength
A apparatus that changes direct current to alternating current.
What is an inverter?
A switch that automatically interrupts or shuts off an electric circuit at the first indication of an overload.
What is a circuit breaker?
An apparatus that conducts the electric current from the machine to the client's skin
What is an electrode?
Provides a uniform source of heat and can be used with hair and scalp conditioning treatments
What are heating caps
Invisible light that has a short wavelength, less penetrating than visible light, causes chemical reactions to happen more quickly
What is ultraviolet light
A rapid and interrupted current, flowing first in one direction and the opposite direction; it is produced by mechanical means.
What is alternating current?
Completes an electric circuit and and carries the current safely away.
What is grounding?
Constant and direct current, having a positive and negative pole that produces chemical changes when it passes through the tissues and fluids of the body
What is galvanic current
Produce moist, uniform heat that can be applied to the head or face
What are steamers or vaporizers
The application of light rays to the skin for the treatment of wrinkles, capillaries, pigmentation, or hair removal
What is light therapy
The unit that measures the pressure or force that pushes electric current forward through a conductor.
What is volt?
Designed to protect from electrical shock by interrupting a household circuit when there is a leak in the circuit.
What are ground fault interrupters?
The process of introducing water-soluble products in the skin with the use of electric current
What is iontophoresis
Effective at combating static electricity and flyaway hair
What are ionic hair dryers and irons
The acronym laser
What is light amplification stimulation emission of radiation
Unit that measures the resistance of an electric current.
What is an ohm?
All electrical appliances you use should be
What is UL certified?
A thermal or heat-producing current with a high rate of oscillation or vibration that is commonly used for scalp and facial treatments
What is Tesla high-frequency
Have built-in heating elements and plug directly into a wall outlet
What are curling or flat irons
Medical device that uses multiple colors and wavelengths of focused light to treat spider veins, hyperpigmentation, rosacea and redness, wrinkles, enlarged hair follicles and pores, and excessive hair
What is intense pulse light
