In blend method a combination of galvanic direct current and low intensity, high frequency alternating current is used to destroy the hair. This method is considered by most users as the best method of hair removal by electrolysis. It is reported to be more effective in removing coarser hairs. (Marica Epiblend E01) 

Shaving 4 to 5 days before treatment is absolutely essential as it makes it easier to identify the affected anagen hairs.

One of the main disadvantages of electrolysis is the duration and the number of treatments needed to obtain a satisfactory and permanent resolution of the excess hair growth problem, at any particular body site. Normally operators can remove only 25 to 100 hairs in one session and individual treatments take any where between 15 minutes to one hour. The discomfort caused by electrolysis is another disadvantage which can be significantly reduced by using a topical anesthetic cream, one hour before treatment. But despite such reduction of discomfort, the treatment remains unsuitable for children.

Hair re-growth to the extent of 15% to 50% has been observed after electrolysis. There are several reasons for this. Since electrolysis uses a sophisticated machine the success rate depends on the operator and varies with the individual operator’s skill. These operators are usually non-medical personnel and the training they undergo varies from place to place.

The current parameters like amount of current, pulse and frequency vary between electrolysis machines, as do the length, diameter, insulation and flexibility of the probes, thereby affecting extent of insertion. Faulty insertion will affect hair destruction. On observation it has been seen that part of the re-grown hair consists of untreated telogen hairs. In case of hirsutism, a faulty set up could result in the transformation of fine vellus hairs into terminal hairs under continuous androgen stimulation. Also telogen hairs are less likely to respond satisfactorily to electrolysis treatment, for reasons as yet unknown.

Generally there is still a lack of standardization of machines, treatment procedures and personnel training. Electrolysis has been found to be most suitable for localized coarse hair growth such as nevoid hypertrichosis.

The side effects of electrolysis include superficial scarring, hyperpigmentation, hypopimentation and local infections.
