High-frequency treatment uses low-current high-frequency alternating currents, delivered via a glass electrode. Because the high frequency current converts some of the oxygen in the air into ozone, the treatment has a germicidal action, and is also drying and warming. Consequently the treatment is used to aid healing, and also to help desquamation (the skin's natural exfoliation), and simulate sweat and sebaceous glands.
At up to 250,000 Hz frequency, the hollow glass electrode behaves like a glow discharge tube, and is sometime called a "violet ray" or "violent wand", (though the colour depends on the gas in the glass). Two electrodes are not required, and sparking may occur when the electrode is close to the skin. Because the effect may be pleasurable, similar devices are used in erotic electrostimulation. [Source: Wikipedia ]This comb is moved on the entire scalp. The treatment generally last for 15 minutes. The advantages of doing this treatment is that the high frequency kills any bacteria or other foreign bodies on the scalp preventing any scalp infection. The scalp has to be healthy for a healthy hair growth, right?
Moreover, the tingling and the vibration improves the blood circulation in the scalp and helps revitalizing the dormant hair follicles. This leads to better hair growth, controls hair loss, helps with dandruff issues as well. Also, the treatment in done in the hair spas so as to ensure better absorption of the treatment serums like hair growth serum or dandruff serums.
In fact, Punam also told me that this treatment is available for skin as well. It helps with breakouts and acne. The electrode is touched on the breakout and the effect is almost immediate. The pimple/acne is gone by the end of day or two. But, she also said that once we stop taking this treatment, the acne does come back. So, its kind of a curable treatment rather than a preventive measure.
I did think that whether its the same case with the hair as well but I think its more of a helpful treatment for hair because it can revive the dormant hair follicles which once revived and taken care of are not likely to become dormant again. It also helps relieve itchy scalp.
That's my theory and I might be wrong but one of my friend has attested that one entire sitting (which includes 4-8 treatments depending on the severity of the condition) of the dandruff treatment hair spa has really stopped her age-old problem of dandruff. So, guess, it might really work.
I do have a feeling that it does work. Yes, I would recommend this treatment especially for the brides who are interested in getting hair growth or preventing hair loss. Its not that expensive either. Do check out the rates across all salons. Have you taken the treatment? How did you like it?
