Effective natural hair loss treatment with the new electric scalp stimulator

Electrical stimulation is often used for pain relief, muscle stimulation, and healing purposes. The surface of the skin is a poor electrical conductor; therefore, the electrical stimuli are usually administered via special conductive pads. If a large area, such as the scalp, is to be treated, this method would be very impractical, especially with hair, as the conductive pads would have to be constantly repositioned. For this reason, a flexible electrical contact is required that can move freely while overcoming the poor electrical properties of the skin surface.

The electrical conductivity of dry skin gradually changes from a near-perfect insulator at the surface to a very good conductor as it approaches the core of the physical body. By placing two adjacent electrically conductive electrodes of opposite polarity on the skin, a stimulating current can reliably flow from one electrode to the other, provided some type of moisturizer is used. As a result, the main component of the electrical stimulus flows along the surface of the skin without reaching the underside of the hair follicles, which are located several millimeters below the surface. Any product that attempts to stimulate the skin via two metal probes in close proximity is not a good idea for follicle stimulation, even more so when done in the presence of existing hair that acts as a perfect insulator.

The above limitation can be overcome if an electrode is placed at a fixed position far from the treated area and another movable electrode is used to treat the affected area. However, the problem of penetration into the insulating surface of the skin remains. Some cosmetic device manufacturers use this approach to skin rejuvenation, but the high voltage required would make this an unpleasant procedure for scalp treatment.

This leads to the ultimate solution in which the electrical stimuli are capacitively transmitted to the skin. By placing an insulating material on the surface of the skin while applying a time-varying voltage to the other side of the insulator, an electrical current flows into the skin. By choosing the right insulating material, its thickness, its contact surface and the power source, an optimal combination can be found. Since the other larger electrode is far from the scalp, it practically connects to the core of the physical body and the electrical impulses therefore penetrate deep into the skin and provide sufficient stimulation of the hair follicles down to the subcutaneous skin without any special contact cream.

The voltage required for the latter process is high enough to cause a corona discharge, which requires clever device design to be approved by regulatory authorities. The very short electrical pulses generated by the device cannot activate muscle contraction. The stimuli are perceived as a very gentle massage and are completely harmless.

The above principle, now embodied in a commercially available product, cannot be ignored by anyone concerned with hair loss. It is one of the most effective methods to prevent hair loss. A small study showed that about 40% of participants experienced excellent hair regrowth results, while the rest benefited to varying degrees. All participants experienced cessation of hair loss. This result exceeds the expectations of other natural hair loss remedies. Electrical stimulation of the scalp not only works well on its own, but can also be used beneficially in combination with other hair loss treatments.
