Galvanic
process of changing chemicals from one kind to another
original modality
only permanent method of hair removal
Dr. Charles E. Michel
1875
opthalmologist, removed ingrown eyelashes
created the profession of electrolysis
Other Names
true electrolysis, chemical decomposition, direct current
Theory of Galvanic Reaction
water: H2O (hydrogen and oxygen)
salt: NaCl (sodium chloride)
Cathode
needle/probe
Electrode
negative pole
NaOH, Sodium Hydroxide, Lye, Alkali
Anode
Sponge
Indifferent Electrode
positive probe
HCl, Hydrochloric Acid, Acid
2 by Products
sodium hydroxide/chlorine gas
hydrogen gas
Lye
caustic agent
sodium hydroxide NaOH
Faradays Law
units of lye
amps (ma) x time (s)
Lye Gradient
the concentration of lye produced in the follicle
stronger = closer to probe
weaker = further from probe
Pattern of Destruction
column shape
Units of Lye Chart
Critical Zone
an area that belongs to the needle within the zone where all tissue is 100% destroyed
outside the zone, the tissue is damaged but can survive
Current Density
amount of electrons that flow into a surrounding tissue, affected by:
needle thickness/diameter/shape
intensity/ma/strength
depth: shallow insertions = greater density (moisture)
Current Intensity
strength of a current flowing from the probe into surrounding tissue
Current Duration
length of time it takes for the probe to flow into surrounding tissue
The current may be available along the entire length of the needle
path of destruction
column shaped
moisture gradient
What pole do you use for lye?
negative pole
What happens if you accidentally use a positive pole with steel needles?
It will produce a steel like spot of black oxide in the follicle, hydrochloric acid not only destroys the tissue, but also destroys metal
tattooing
Side effect of acid in the palms of hands
Can produce hydrochloric acid rash/indifferent electrode rash/ erythema
Cataphoresis
postive pole
roller
indifferent electrode produces:
HCl = Acid
inactive
firms skin
soothes skin
reduces redness
calms the skin
Anaphoresis
illegal
negative pole
produces lye - NaOH
active
irritates skin
softens and releases
produces lye
Phoresis
forcing a liquid through an unknown membrane = electrotherapy
Side Effects of Galvanic
mass shocking - multi needle technique
Professor Paul Kree
1916, invented the multi needle technique
Positioning the Handheld Electrode
always choose the shortest electrical path
do not allow the current to flow through metal in the body
if metal in body, choose opposite side
Pros of Galvanic
highest success rate
percentage of regrowth is 0%
inaccurate insertions are unimportant
distorted and wavy follicles can be treated
lye continues to destroy hair follicles even after treatment
Cons of Galvanic
slowest method
number of minutes per hair
client cooperation
lye continues to irritate area
tattooing and indifferent electrode rash
painful
