Electrolysis and laser hair epilation are the only hair removal methods that may provide a permanent result.
Electrolysis involves the insertion of a small fine needle into the hair follicle, followed by a small electrical current that damages and eventually destroys the hair follicle. There are 3 different methods (modalities) to achieve this:
- Galvanic electrolysis
- Thermolysis
- Blend method
Galvanic electrolysis
This uses direct current electrolysis, which means a direct electric current is passed down a needle into the hair follicle where it creates a chemical reaction. This reaction converts tissue saline into sodium hydroxide, a caustic agent that then destroys the hair bulb.
Thermolysis
This uses a high frequency alternating current that is passed down through the needle to the hair follicle. The high frequency causes vibration in the cells of the hair follicle to produce enough heat to cauterize the hair bulb.
Blend Method
This combines both the galvanic and thermolysis modalities.
No clinical trials have been carried out to compare the methods and any claims of one method being more effective over the other is based on anecdotal evidence only.
How effective is electrolysis?
Effectiveness of electrolysis is dependent on the skill of the technician (electrologist) performing the procedure. Proper electrolysis requires accurate needle insertion technique and use of appropriate intensity and duration of current. The technician, based on the patient's pain threshold, sets the intensity measured in milliamps, and the duration of the current is controlled by how long the technician presses down on the hand or foot pedal. A common estimate of effectiveness is that 25% of treated hair don't regrow.
Electrolysis is a very slow method of hair removal that may also be prolonged by having to do repeat insertions into the hair follicle. It may take a minute or more to remove each hair using galvanic electrolysis.
The amount of pain experienced during the procedure is dependent on the individual's pain threshold. Topical anaesthetic creams applied one hour before the procedure may help to reduce discomfort. However, it is desirable to maintain some sensation as the pain is related to the amount of damage to the hair follicle.
Who is suitable for electrolysis?
Almost anyone wanting to remove unwanted hair is a candidate for electrolysis. For men and women electrolysis is usually a safe and permanent process of hair removal. However, it is should not be used for patients with pacemakers because it can interrupt the electronics to cause potentially dangerous heart rhythms.
Complications
Some degree of redness about treated hair follicles for a few days is not uncommon.
Potential risks of electrolysis include scarring and increased or reduced pigmentation i.e. brown or white marks.
Secondary local infection with bacteria (impetigo) or reactivation of herpes simplex are also possible complications.

Does electrolysis really remove hair permanently? ›
Yes. Unlike other hair removal methods that offer a temporary solution, Electrolysis is permanent and is the only FDA approved method of permanent hair removal.
What is a downside to electrolysis? ›
Electrolysis Cons
It's a time-consuming procedure requiring multiple sessions. Skin discoloration is a possibility. The electricity in the device can actually destroy the capillaries in the surrounding areas. It can be very painful. It is not recommended for people with rosacea since the skin is so easily irritated.
Is electrolysis really painful? ›
Some common myths about electrolysis include: Electrolysis is very painful. For most people, today's methods don't cause a lot of pain, but it can hurt. If you find it too uncomfortable, your doctor may be able to give you an anesthetic cream.
How long does hair electrolysis last? ›
Expect to go through around eight to twelve sessions for a permanent result. That may seem like a lot. However, it's important to remember – the results last forever. Indeed, the Food and Drug Administration (FDA) and the American Medical Association (AMA) consider electrolysis the only permanent hair removal method.
Why is electrolysis hair removal not popular? ›
Another major drawback of the electrolysis method is that it can't be done for a large body surface area, and it also sometimes leads to scar formation. Laser hair removal requires fewer sessions than electrolysis. Laser hair removal usually takes about 4 to 8 sessions for best results.
Does hair fall out immediately after electrolysis? ›
After any one session, expect a 50 to 60 percent drop off in hair growth. During the initial few sessions, hairs will begin to regrow after one to six weeks – as these hairs were dormant at the time of the procedure.
Who should avoid electrolysis? ›
Absolute Contra-Indications – Requires a Doctor's Note: Diabetes, heart condition, hemophilia, pacemaker, seizures, transplant, surgery.
How many hairs can be removed in one electrolysis session? ›
How Much Hair Can Be Removed in One Session? Electrolysis damages roughly 35% of hair per session — the amount may be lower or higher depending on your hair type. An electrologist may be able to eliminate soft hair quicker than coarse hair since the former is easier to destroy.
What can go wrong with electrolysis? ›
Electrolysis can cause scarring, keloid scars, and changes in skin colour of the treated skin in some people.
Under and near the nose is the single most sensitive area for electrolysis on the face. I also had electrolysis on my genitals prior to SRS and every zap in that area hurt much more than the any facial electrolysis.
What does your face look like after electrolysis? ›
Most side effects of electrolysis are mild but may include redness, swelling, blisters, scabs, dryness, and ingrown hairs.
What happens if you stop electrolysis? ›
It is therefore very important that electrolysis is performed upon the detection of re-growth. Left untreated, hair will reconstitute itself to its original diameter and depth. Once a treatment program begins, it is important that appointments are kept to the predetermined schedule set at the beginning of your program.
Does plucking hair ruin electrolysis? ›
Once you start Electrolysis refrain from plucking, waxing or threading. Any method that requires to pull the hair from the root will slow down your progress.
Can you see results after one session of electrolysis? ›
Clients Should Come for a Minimum of 10 Sessions
Another general rule of thumb is that most clients will need to come for at least 10-14 sessions before the full electrolysis results will kick in. However, this is just a minimum. Some people may have to wait 8-18 months to see the full results.
How many electrolysis sessions to permanently remove hair? ›
Generally speaking, you are likely to require between 8 and 12 treatments. The average time from start to finish is about 12 months. It can take anything from 8 months up to 2 years in some cases. The total number of sessions needed to remove hair permanently from a particular area will vary from person to person.
What is the success rate of electrolysis hair removal? ›
Electrolysis only destroys about 35 percent of hair follicles per session, says Elise, so it can take up to 18 electrolysis sessions spaced three to four weeks apart to completely remove hair from a single area, says Elise. Remember: Permanence takes time, especially when you factor in how your hair grows.
Is electrolysis 100% permanent? ›
Traditional Electrolysis
Regardless of the cause – heredity, metabolic, or hormonal conditions – electrolysis will permanently remove unwanted hair to reveal a glowing, confident you.
