van zeynek

49
Q

which modality was invented in 1938 by arthur hinkel and henry st pierre

A

the blend

50
Q

what modality utilizes heated lye?

blend

51
Q

which modality destroys tissue with chemical electrocoagulation (congeal) or chemical electrodessication (dry up)

A

the blend

52
Q

what does electrodessication mean?

A

to dry up

53
Q

what is electrocoagulation?

A

congealing

54
Q

what heats needle in thermolysis?

A

the moisture in the skin

55
Q

what causes blowout?

A

intensity is to high and skins moisture boils producing steam

56

Q

what is the characteristics of bulbous insulated probes?

A

creates greatest amount of lye at their tip , effective with galvanic

58
Q

what are the characteristics of cylindrical no insulated probes?

A

preferred with galvanic current, evenly distribute lye throughout the hair shaft

59
Q

in direct galvanic electrolysis which direction do electrons flow in?

A

negative to positive (goes into hair follicle, through body, to positive current

60
