What is the primary effect of high-frequency treatments?

High-frequency treatments primarily stimulate blood circulation and promote healing, making this the correct answer. These treatments utilize electrical currents that help to oxygenate the skin and enhance metabolism at a cellular level. This increased blood circulation not only delivers more nutrients and oxygen to the tissues but also aids in the removal of toxins, leading to improved overall skin health and a more vibrant appearance.

While reducing hair loss can be a secondary effect of high-frequency treatments through improved scalp circulation, it is not the primary effect. Similarly, enhancing hair color and moisturizing the skin may occur, but they are not the primary outcomes associated with this treatment method. The main goal of high-frequency treatments is to support the skin’s health by stimulating blood flow and promoting the healing process, making option B the most accurate choice.
