How does the Tesla high-frequency current primarily benefit hair follicles?

1. Increases hair growth

2. Prevents dandruff

3. Reduces oiliness

4. Softens hair texture

The correct answer is: Increases hair growth

The primary benefit of Tesla high-frequency current for hair follicles is that it stimulates hair growth. This electrical treatment increases circulation within the scalp, leading to improved nutrient and oxygen delivery to hair follicles. Enhanced circulation can invigorate dormant hair follicles, potentially leading to increased hair density and growth. The application of high-frequency currents can also help to clear blockages in hair follicles, which is essential for optimal hair growth. Furthermore, the subtle thermal effect from the current may stimulate the production of natural oils, which contribute to healthier hair. In this context, the emphasis is on promoting a conducive environment for hair growth rather than just cosmetic benefits. Other effects, while beneficial in other contexts, do not directly contribute to the primary purpose of Tesla high-frequency current in relation to hair follicles.
