Which treatment should a stylist avoid using on hair that has heavy grease deposits?

Electrotherapy should be avoided on hair that has heavy grease deposits for several reasons. This treatment involves the use of electrical currents for various purposes, including stimulation of the scalp and hair follicles. However, using electrotherapy on excessively greasy hair can lead to several complications. The buildup of grease can create a barrier that prevents effective treatment absorption, leading to diminished results. Furthermore, the presence of heavy grease may hinder the electrical current's conductivity and effectiveness.

Additionally, electrotherapy does not address the underlying issue of heavy grease deposits, which can come from product buildup or scalp oil. Before applying electrotherapy, the stylist should focus on cleaning the hair thoroughly to remove grease and product buildup. This ensures that the treatment works optimally and doesn't create an undesirable or ineffective experience for the client.

In contrast, options like clarifying treatments are specifically designed to remove such deposits, while deep conditioning and hot oil treatments target moisture and nourishment, which can be beneficial only after addressing any grease buildup.
