Unit 3.19 – Identify treatment modality Copy

Electrolysis is the general term used to refer to permanent hair removal. The principal methods used
1. Electrolysis uses a direct current (galvanic). When applied through the probe, the current
produces a chemical called ‘lye’ which destroys the growing cells and the papilla.
2. Thermolysis uses radio waves to generate heat. The effect is to coagulate the papilla (blood
supply) to prevent it from feeding the bulb. This prevents the follicle from producing more
3. A blend of the two types can be used for efficiency and comfort.
All three methods are applied by using a fine probe which is inserted into the hair follicle without
breaking the skin. When the probe is in position, the correct amount of one or both currents is
applied. The object of the treatment is the successful discharge of current or energy at the base of
the hair follicle, minimising damage to surrounding tissue and maximising destruction or causing a

reduction of the follicle’s ability to create new hair. Removal of the hair after the treatment pro-
duces an immediate improvement in appearance. An understanding of the structure of hair and the

causes of hair growth patterns as well as practical expertise in permanent epilation techniques are
required to successfully achieve permanent hair removal.
