A petrissage scalp massage involves which of the following techniques?

The technique of petrissage in a scalp massage is characterized by the gentle pushing and kneading of the scalp. This specific method promotes relaxation and helps stimulate blood circulation in the scalp area, which can be beneficial for hair health and overall relaxation. Petrissage involves rhythmic squeezing and manipulation of the tissues to encourage muscle relaxation and improve mobility.

In contrast to other techniques listed, such as tapping, rubbing, or applying pressure only with the thumbs, which serve different purposes and provide varied sensations, the petrissage technique focuses on a more comprehensive engagement of the scalp's muscles and tissues, promoting both relaxation and stimulation effectively. This is a vital skill for hair professionals to master, as it enhances the overall client experience during services such as haircuts and treatments.
