What are the effects of the rotary on the hair and scalp?

The rotary movement of a hairbrush or massager can stimulate blood circulation in the scalp, promoting hair growth and overall scalp health. This action can also help to distribute natural oils evenly along the hair shaft, enhancing moisture and shine. Additionally, the gentle massage can relieve tension and stress, contributing to a more relaxed and healthy scalp environment. However, excessive or harsh rotary motion may lead to hair breakage or scalp irritation, so it’s essential to use gentle techniques.
