A client who knows what to expect is calmer, tenses up less and tolerates the treatment better. A client surprised by the course of the treatment more often gives up after the first visit, even if everything went well technically. That's why knowing the whole process, from the first phone call to home care, is as important for the person performing the treatment as the needle work itself.
This article takes you through the whole treatment in order. It will be useful both to cosmetologists setting up their procedure and, indirectly, to clients who come across it while looking for information before their first visit.
What does an electrolysis treatment look like from start to finish?
The treatment consists of five stages: a consultation with a health questionnaire, preparing the skin and workstation, the actual needle work, assessing the skin's reaction at the end and aftercare. The needle work itself involves inserting the needle along the hair into the follicle and delivering a pulse, after which the hair slides out without resistance. The whole visit lasts as long as the booked working time, because electrolysis is charged by time, not by area.
It's worth noting straight away that the first visit looks different from subsequent ones. The first session includes a full consultation, a health questionnaire and usually a shorter test treatment, during which you both check how the skin and hair react. Subsequent visits run more smoothly, because you already know the client's hair type and the parameters chosen earlier.
How do you prepare a client for her first electrolysis visit?
The most important rule is that the hair must be visible and possible to grasp with the needle, so for several weeks before the treatment it must not be pulled out with wax, tweezers or an epilator. Shaving is allowed and doesn't interfere, because it leaves the root intact. This is the first piece of information you give the client even before booking an appointment, because it determines whether the treatment can be performed at all.
This rule can surprise clients, because with other methods it's the other way round. So it's worth explaining the logic: electrolysis works on hair connected to the follicle, and wax and tweezers pull that hair out, so for the following weeks there's nothing to treat. Shaving only shortens the hair above the surface and doesn't touch what's under the skin.
Apart from that, it's worth asking the client to come to the visit without make-up in the treatment area, in the case of the face, and to avoid tanning and strong sun in the days before the session. Skin irritated by the sun tolerates the treatment worse, and it's harder to choose safe parameters for it.
What happens during the pre-treatment consultation?
The consultation consists of a health questionnaire, an assessment of the area and hair, and agreeing a plan for the series. It's the moment when you check for contraindications and decide whether to take the client at all. The client fills in and signs the health questionnaire, and you keep it in your records.
During the interview you ask directly about things the client won't mention on her own: implanted devices, chronic diseases, medications, pregnancy, a tendency to scar and treatments performed in recent months. It's not a formality, but real protection against taking someone you shouldn't have taken. I've put together a full list of situations you need to ask about and which may rule out treatment in the article on electrolysis contraindications.
The consultation is also a conversation about expectations. You explain that electrolysis is a series of treatments, that some hairs will grow back after the first session and that the result builds up gradually. A client who leaves the consultation with a realistic picture of the process stays for the whole series. One with false expectations leaves disappointed, even if the treatment was performed flawlessly.
How are the skin and workstation prepared before the treatment?
The skin in the treatment area is cleansed and disinfected, and the workstation is prepared in line with hygiene rules: a single-use needle taken out of its packaging in front of the client, gloves, and disinfected surfaces and handpiece. The needle is always new, single-use and opened in the client's presence, which is worth showing her, because it builds trust and a sense of safety.
Preparing the workstation is something you learn together with health and safety rules, because the safety of a treatment that breaks the skin depends on hygiene. A well-organised workstation also speeds up the work itself, because everything is to hand and you don't waste time looking for a gauze pad halfway through the session.
At this stage you also choose a needle for the hair thickness and skin type and set the device's initial parameters. For clients with a nickel allergy, gold-plated needles are used. All of this happens before the first insertion.
What does the actual needle work look like during the treatment?
The needle is gently inserted along the hair, in the natural direction of its growth, down to the bottom of the follicle, and then a pulse is delivered. A properly treated hair slides out after the treatment without the slightest resistance when gently grasped with tweezers. If the hair resists when being removed, it means the energy was too low or the needle didn't hit the follicle precisely, and the hair is treated again.
This is the most important and most demanding moment of the whole treatment. The insertion angle, depth and choice of parameters determine everything: effectiveness, the client's comfort and whether a mark is left on the skin. A needle inserted at the wrong angle delivers energy into the tissue around the follicle instead of to its base, which hurts more and gives a worse result. That's exactly why this precision is learned on models under an instructor's supervision, not from videos.
During a session the working mode often changes depending on what's under the needle at the moment. Fine facial hair needs a different setting from thick hair in the bikini area. The ability to move smoothly between methods within one session is one of the things that distinguishes a beginner from an experienced electrologist, and the methods are matched to the specific hair type and the sensitivity of the area.
Does electrolysis hurt?
The sensation depends mainly on the body area, individual sensitivity and the precision of insertion. It's most often described as a brief prick or a feeling of warmth with each hair, quite bearable, although some areas, such as above the upper lip or the bikini line, are more sensitive. A properly performed treatment is much less unpleasant than is commonly believed, and the biggest difference here is made by technique, not the method itself.
There are several ways to reduce discomfort: shorter sessions on sensitive areas, breaks at the client's request, well-chosen parameters and conversation that distracts. On request and after assessing the skin, numbing products can be used, although many clients find after the first session that they aren't needed. It's worth asking the client after the first few hairs how she's tolerating the treatment and adjusting the pace.
What does the skin look like immediately after electrolysis?
Right after the treatment, the skin in the treated area may be red and slightly swollen, and small dots may appear at the insertion points. This is a normal, temporary reaction that usually subsides within a few hours to a day or two. The intensity depends on skin sensitivity, the area and the length of the session, and decreases as the skin gets used to the treatments over subsequent visits.
At the end of the session, the skin's reaction is assessed and a soothing product is applied. It's also the moment to give the client aftercare instructions, ideally in writing too, because they're easy to forget after the visit. The client should know what to avoid over the next few days, and what is a normal reaction and what is a reason to get in touch.
How should you care for the skin after electrolysis?
For a few days after the treatment, avoid touching and scratching the area, hot baths, sauna, swimming pools, intense physical exercise, and tanning and sunbeds. Keep the skin clean, don't apply make-up to the freshly treated area and use the soothing products recommended by the person who performed the treatment. The goal is calm healing without irritation and without the risk of pigmentation changes.
Sun protection is particularly important. Freshly treated skin is more prone to post-inflammatory hyperpigmentation, so for exposed areas such as the face, a high-SPF cream is recommended for several weeks. It's the recommendation clients most often ignore, yet it really affects how the skin looks after the series.
It's also worth warning the client not to pluck or wax hair between sessions, because it knocks the whole process out of rhythm. Shaving is allowed. Why regularity and refraining from plucking matter so much for the result is explained in more detail in a separate article on how many sessions are needed for a permanent result.
What mistakes are most often made during the treatment?
The most common mistakes are the wrong insertion angle, poorly chosen parameters, running sessions over the booked time and skipping the assessment of the skin's reaction at the end. Each of them affects either the result, the client's comfort or the profitability of your work.
The wrong insertion angle is a technical mistake that becomes ingrained if nobody corrects it during training. That's why starting out under an instructor's supervision matters so much, because practising alone from scratch carries the risk of developing a habit that's hard to reverse later. Poorly chosen parameters mean either too little energy and a hair that resists, or too much and irritated skin.
Running a session over looks like courtesy, but it's a costly habit. A client booked for an hour stays for an hour and a half because “there's just a bit left”, and with twenty visits a month you give away several fully paid hours. The session ends when the booked time is up, and an unfinished area is a natural reason to book the next visit.
How long does a single electrolysis treatment take?
The length of the session is agreed with the client in advance and usually ranges from a dozen or so minutes to about an hour, depending on the area, sensitivity and the time booked. The first visit is often shorter, because it includes a test treatment to check how the skin reacts. Not all the hair is removed in one visit, because only hairs in the right growth phase can be permanently treated.
To the treatment time itself, it's worth adding the consultation at the first visit and preparing and cleaning the workstation at every visit. The real time reserved in the schedule is therefore longer than the needle work itself, which is worth remembering when planning your treatment calendar.
Why is it worth learning the whole procedure, not just the insertion technique?
Because whether a client comes back depends on the whole experience, not just a correct needle insertion. An efficient consultation, a calm atmosphere, clear instructions and a well-chosen session pace build the trust that brings the client back for visits over many months. Technique alone, without the rest of the procedure, isn't enough to build a regular schedule.
That's why a good course teaches the whole thing: from the health questionnaire, through workstation hygiene and choosing parameters, to work on models and aftercare.
