One of the most immediate and obvious benefits of a scalp massager is that using it feels fantastic and helps relieve stress. Any type of scalp massager, including fingers, will increase your scalp’s circulation. Increasing blood circulation anywhere in the body is beneficial simply because better blood flow delivers nutrients and oxygen to your cells. A scalp massager can also exfoliate your skin and increase follicle circulation. Serums may be absorbed better when your scalp’s blood vessels are dilated as well. Additionally, a scalp massage with tea tree shampoo can help heal ingrown hairs on your scalp.
One persistent claim about massaging the scalp is that it may promote hair growth, but experts are divided on this. Dermatologist Dr. Morgan Rabach shared with Harper’s Bazaar that, “There is no scientific evidence to support increased hair growth,” though she conceded that increased circulation is beneficial.
However, board-certified dermatologist, Dr. Aleta Simmons told Byrdie that, “Scalp massagers can cause mechanical stress on the scalp, potentially leading to alterations in gene expression. These changes may lead to increased hair thickness.” Research is limited, so we say, stay tuned. Speaking to Allure, trichologist Penny James cautioned against relying on a scalp massager for relief from psoriasis, scalp irritation, or dandruff since the stimulation can cause inflammation and worsen the condition.
