The blend method combines which two modalities?

The blend method in electrolysis specifically combines high frequency and galvanic current. This technique leverages the advantages of both modalities to enhance the effectiveness of hair removal.

High frequency refers to the use of alternating current (AC) to produce heat within the hair follicle, facilitating the destruction of the hair cells. This method acts quickly and effectively, making the process more efficient.

On the other hand, galvanic current involves a direct current (DC) that creates a chemical reaction in the follicle, specifically the production of lye (sodium hydroxide) which destroys the hair structure.

By combining these two methods in the blend technique, practitioners can achieve faster and more thorough hair removal. The simultaneous application allows for the benefits of both heat and chemical action, leading to stronger results while often reducing discomfort for the client.

The other options do not accurately represent the modalities that comprise the blend method, focusing instead on different technologies and methods that are not part of the traditional blend approach.
