Which of the following is a benefit of correct hair brushing?

Stimulating microcirculation to the scalp is a significant benefit of correct hair brushing. When you brush your hair, the gentle action helps to increase blood flow to the scalp, which can enhance the delivery of oxygen and nutrients to hair follicles. This improved blood circulation can contribute to healthier hair growth by nourishing the follicles and encouraging stronger hair.

While other choices mention benefits related to hair health and appearance, such as preventing tangling and promoting volume, they are not as directly linked to the physiological impact on the scalp as microcirculation. Therefore, the effect of brushes in promoting blood flow is a fundamental advantage that contributes to overall hair vitality.
