When to use petrissage massage when shampooing?

Petrissage massage is typically used during shampooing to enhance relaxation and stimulate blood circulation in the scalp. It is best applied after the initial cleansing phase, while the hair is still wet and lathered with shampoo, allowing the fingers to knead and lift the scalp gently. This technique can help alleviate tension, improve product absorption, and promote overall scalp health. It's especially beneficial for clients looking to enhance their shampoo experience with added relaxation.
