Blend does exactly what its name suggests: it brings galvanic and thermolysis together in the same follicle, at the same time. The idea is to capture the strengths of both, the completeness of the chemical action and the speed of heat, in one efficient treatment.
It is a versatile, widely used method, and it is often the one practitioners reach for when hair is coarse, deep or has been distorted by years of tweezing or waxing.
How blend works
With the probe in the follicle, a direct current begins the galvanic chemical reaction while a high-frequency current adds heat. The heat warms the lye produced by the galvanic action, making it more active and helping it work more quickly and thoroughly than galvanic alone.
The result is a method that reaches deep, awkward follicles like galvanic but works faster, which is why blend is such a dependable all-rounder.
When blend is a good choice
Coarse or stubborn hair
The combined action is well matched to thick, deeply rooted follicles that resist gentler approaches.
Distorted follicles
Hair that has been repeatedly plucked or waxed often grows from a curved follicle; blend follows and treats it thoroughly.
A balance of speed and completeness
It offers much of galvanic thoroughness without being as slow, making it practical for a range of areas.
