What is electrolysis?

Electrolysis applies electrical energy to individual follicles to stop hair production. It requires specific training; this is not an instruction for home treatment.

Which technological approaches exist?

Galvanic electrolysis uses direct current for chemical action; thermolysis uses high-frequency alternating current to produce heat. Blend combines both.

Why is it considered for light-coloured hair?

Electrolysis does not rely on hair pigment absorbing light. The AAD includes it as an option for light-coloured hair.

What does a permanent result mean?

Permanent removal does not mean completion in one visit: hair cycling can require several sessions.

Which risks should we discuss?

Risks include discomfort, redness, burns, scarring, pigment changes and infection. Discuss herpes, a tendency to scar and electronic implants, particularly a pacemaker, beforehand.

Is one mode best for everyone?

Compare methods using the same questions: what is being offered, how will the outcome be assessed and what remains uncertain? A mode name cannot replace those answers.

Which consultation questions are helpful?

Ask about qualifications, experience and infection prevention. Request an understandable explanation of why the selected method is appropriate and how to contact the clinic if a problem occurs. Ask the practitioner to distinguish ordinary temporary reactions from symptoms requiring assessment. You should have time to decide; rushed consent cannot replace informed choice.

How should we assess a treatment promise?

If an offer depends entirely on the word “permanent”, ask for specifics. Which area does the plan concern, how will change be recorded and what will later assessment use? Clear expectations matter as much as the method’s name. A broad promise cannot replace discussion of individual characteristics, visits, discomfort and unwanted reactions. Choosing a method does not oblige you to start that day.

What is the difference between a device and a service?

The device is only one part of a service. Catalogue data describe equipment, while training and infection prevention concern the setting in which a procedure is performed. Information about one does not establish the other. Buying equipment and choosing a procedure therefore require different documents and questions. A good consultation explains this boundary and does not imply that owning a device establishes clinical experience.
