Electrolysis Test 1 Flashcards
(38 cards)
What are the 3 types of terminal hair, and examples?
Asexual - scalp/eyebrows. Ambisexual - underarm/pubic.
Sexual - beard/chest.
Describe the Anagen stage of hair growth.
Germinating cells in the matrix begin forming the hair bulb, which is nourished by the dermal papilla. As new cells are added to the upper part of the bulb, they become the hair shaft. Melanocytes release melanin, which gives the hair its color. The shaft continues to grow upward until it reaches the top of the follicle. As it grows, sebum is released to lubricate the hair.
What is the cause of PCOS and three symptoms?
Cysts on the ovaries, usually benign. results from a hypersecretion of FSH stimulating the ovaries. Which become inflamed blocking the release of eggs.
Three symptoms
-Acne
-Obesity
-Excessive facial or body hair
What is the treatment plan and advice for PCOS?
-weight loss through diet and exercise
-drugs(contraceptive pill to control hair growth, acne and menstrual cycle)
-surgery to remove cysts
-electrolysis is successful once condition is under control
What is the cause of Cushing’s syndrome and three symptoms?
Adrenal gland becomes overactive secreting excess levels of androgen hormone, tumor on the adrinal gland or use of steroids.
3 symptoms
-weight gain
-stretch marks
-abnormal hair growth
What is the treatment plan and advice for Cushing’s syndrome?
Surgery, drugs to decrease cortisol secretion from adrenal gland, electrolysis can be successful once condition is under control.
What is hypertricosis and two characteristics of this?
Hypertricosis is excessive hair growth over the body. It can be vellus unpigmented or dark terminal hair.
Stimulated by injury or disease.
What is normal, congenital hair growth?
It is inherited and normal for that persons age, race and sex.
Characteristics from our mother. Can be present from birth or accumulated later in life.
What is the formation of lye around the needle during galvanic electrolysis?
Lye forms in an even cylindrical pattern around the needle. Greater concentration closer to the needle, longer the current flows the wider the lye pattern becomes.
What are two factors that stimulate hair growth?
Hormones and increased blood supply
How does galvanic current destroy the hair follicle?
Using a chemical process to destroy the tissue, sodium hydroxide is produced which is a strong alkaline, this dissolves the tissue.
What are two factors that stimulate hair growth?
Hormones and increased blood supply
What is an alternative
name for high frequency?
Alternating current
Does high frequency require a circuit?
No
What different polarity’s does high frequency use?
Negative and positive.
What is another name for galvanic?
Direct current.
Does galvanic current require a circuit?
Yes
What polarity does galvanic use?
Negative
What are 3 things that galvanic needs to enhance lye?
-Time, longer in follicle more lye produced
-Intensity, higher current more lye produced
-Moisture gradient, moisture is required to produce lye, lower part of the follicle has a higher moisture content
How does high frequency work?
Particles are excited in the tissue due to the polarity change which creates friction and heat causing coagulation.
Describe the heating pattern for high frequency. Three points please!
-Coagulation occurs at the tip of the needle the heating pattern expands outwards and upwards in search of moisture
-Tear/pear shape heating pattern in the follicle
-Tissue coagulation occurs at the tip of the needle first
What are 3 variables to consider with HF?
-Time, the longer the current is on the greater the heating pattern and tissue coagulation
-Intensity, higher the intensity quicker coagulation occurs
-Size of the needle, thinner needles produce more heat and coagulation, thicker needle generates less heat and coagulation
What are 2 scenarios where you would use HF over galvanic and why?
-When client finds galvanic too painful
-When unable to divert direct current flow around a metal implant.
-Clearing area quickly
Why is blend so effective? 3 points please!
Heating- speeds up formation of lye and warms lye.
Permeability-coagulates tissue, increasing absorption of lye.
Turbulence-lye and tissue fluids move deeper into the lower follicle due to being heated
