Which treatment is commonly used to improve the health of the scalp?

Scalp massage is commonly used to improve the health of the scalp due to its various beneficial effects. This practice enhances blood circulation in the scalp area, which can promote healthier hair growth by ensuring that hair follicles receive essential nutrients and oxygen. Scalp massage also helps to relieve tension, reduce stress, and can improve overall relaxation, contributing to a healthier scalp environment.

While deep conditioning treatments can benefit the hair itself, and facial treatments and hair coloring generally focus on the skin of the face and the hair's aesthetic appearance, respectively, they do not specifically target the scalp's health in the same way that a scalp massage does. Thus, scalp massage stands out as the treatment that directly improves scalp health.
