The measurements of intensity, duration and treatment energy is determined in the following ways:
Galvanic machines are measured in mA. 0.1–1.0 mA. (0.3 – 0.7 mA average).
Thermolysis machines are measured in radio frequency watts. Most machines do not have a visible read out, but instead have a scale of relative value ranging from 0 – 10 or 10 – 100. The thermolysis intensity control knob (rheostat) has a scale, for example,
1 – 10 or low to high. Most individuals can tolerate a level between 2 and 4 on a knob that has a scale of 1–10.
Duration is measured in seconds. Electrologists with foot pedals can count seconds by saying – 1001, 1002, 1003, 1004 etc.
The timings for each method are:
− Thermolysis average hair 5 seconds
− Galvanic average hair 30 seconds
− Blend average hair 8 seconds
• Treatment energy
Some machines have a treatment energy selector, the range is from 0 to 125 units, the average hair requires 50 to 60 units.
