the part where mitosis, or cell division take place The Papilla What are the three sections of the hair shaft from innermost part of the hair to outward Medulla, cortex and cuticle What is the innermost section of the hair and it is found only in terminal hairs Medulla What is the second or middle layer, and is considered the thickest layer; also holds the melanin Cortex What gives hair it's color Melanin What is the third and outermost layer of the hair; it helps protect the inner layers of the hair and also help anchor the hair into the follicle ; it is made of keratin ; it offers protection because of it's hard, fibrosis makeup Cuticle What are two important components of the nutritional process of hair Blood and hormones What have the ability to facilitate hair growth and influence other processes such as rates and other growth such as changing vellus hair to terminal hair ; are supplied through the papilla Blood and hormones What is the carrier of nutrients and hormones Blood What is the most important male hormone Testosterone If a female has too many free and circulating androgens in her body she can have Unwanted side effects such as turning vellus hair on her lip and chin too thick and dark terminal hair What will transport your hormones to its target sell, or assigned location Your blood How many stages does your hair go through in life Three What are the three phases of hair growth in the order of which they take place Anagen, catagen, telogen What is the growing phase of hair; the hair bulb is attached to and has completely engulfed the papilla Anagen What encourages mitosis, or subdivision Anagen What is the most important phase of the hairs life, because this is the face we need the hair to be in, in order to successfully epilate the hair whether it's by laser or electrolysis Anagen The deepest length of your anagen hair growth two is 6 mm and it is often referred to as Anagen 6 What is another factor that helps electrical currents and aids electrolysis Increased follicular moisture What is the transitional phase; the hair is literally transitioning from growing to resting Catagen What The papilla to the hairball so there might be very minimal cell growth and very minimal Mélinand production Epidermal cord What is the phase where the club hair begins to form but is not the club hair Catagen What is the resting phase; the hair is completely detached from the papilla and there is absolutely no cell growth and no Mélinand production Telogen What is often referred to as club hair; acts like an anchor; dried out, white, hard and round like a club Telogen What is the carrier of color; the molecules inside tissue that gives it its color Chromophore One of the three properties of laser lights; waves that travel in the same direction, have the same wavelength, and are in the same phase Coherent Parallel radiation, all particled travel parallel to each other Collimated radiation Type of melanin which is responsible for dark and brown color Eumelanins One chromatic of color Mono chromatic light Type of melanin that gives blond and red when eumelanin is not the dominant pigment Pheomelanin The portion of the electromagnetic spectrum that humans perceive as light Visible spectrum What is defined as the movement of electrons along a conductor Electricity What is a basic unit of matter that is made up of protons, neutrons and electrons Atom What is the center of the atom; made up of a combination of protons and neutrons while the electrons orbit around The nucleus If the number of protons and electrons within and Adam are equal and the Adam will have No charge for a neutral charge If there are more electrons than protons, the Adam will have a Negative charge When atom has a positive or negative charge it is called an Ion We measure light in Nano meters and wavelengths What is the type of light where all the waves are in phase with each other Coherent light Laser light is Coherent light Laser is an acronym that stands for Light amplification by stimulated emission of radiation What is a quantity of light Photon What will produce a wavelength of 694.3 nm A ruby laser What laser will produce a wavelength of 755 nm Alexandrite What will typically range between 800 nm to 810 nm A diode What will produce a wavelength of 1064 nm NdYag In order for a laser two ladies must possess the following characteristics Mono chromatic, coherent, collimated What is referred to as polychromatic IPL What uses light source that creates wavelengths in the range of 500 nm to 1200 nm IPl What will naturally be in a resting state that is called a ground state Electrons When the electron releases energy it will fall back into a lower or intermediate energy states this is called Metastable state What is well-known bad radiation that can cause cellular mutation and or death Ionizing radiation What is a non-ionizing radiation meaning there is no cellular mutation and or death Laser What is energy and it can be absorbed and changed into another form of energy, and in our field that energy will be heat Light Who proposed the theory of stimulated emission in 1917 Albert Feinstein Who was credited with treating the first patient with a medical laser Charles J Campbell Who used a ruby laser to destroy a retinol humor Charles J Campbell
