Does high-frequency hair treatment have side effects?

What most people experience

Very little, which is the honest answer. A glass electrode passes over the scalp delivering a low, high-frequency current. Most patients describe a gentle tingling or slight warmth. It is not painful, nothing is injected and no anaesthesia is used.

Afterwards the scalp may look slightly red for a short while. That settles quickly and you can go straight back to your day — there is no downtime to plan around. Sessions run about 15 to 20 minutes.

You may also notice a faint smell during treatment. High-frequency devices generate a small amount of ozone at the electrode; it is a normal property of how they work, not a sign anything is wrong.

Who it is not performed on

This is the part that matters more than side effects, and it is not negotiable. High-frequency is not carried out if you:

• have a pacemaker or an implanted cardiac device
• have a heart condition
• have epilepsy
• are pregnant

Your medical history is screened for all four at the consultation before anything is switched on. Tell the doctor about implants, recent scalp procedures or an irritated scalp even if you are not asked directly — timing may be adjusted.

If you colour or chemically treat your hair, that is usually fine, but say what you have had done and when.

The bigger caveat: what it does not do

High-frequency supports scalp condition and circulation. It does not treat the underlying cause of pattern hair loss, and it will not stop hair fall on its own.

That is worth stating plainly, because it is the misunderstanding that costs people time. If your hair is thinning, the treatment that helps is the one aimed at the cause, and finding the cause is a diagnosis — see hair fall treatment and the hair regrowth options. High-frequency is used alongside a plan like that, not instead of one. Where the problem is dandruff and scalp congestion specifically, anti-dandruff treatment is the more direct route.

A doctor at either clinic will tell you which of these your scalp actually needs. The consultation is ₹500, waived against treatment. Full detail is on the high-frequency treatment page.
