Back to Basics | Tools of the Trade

Written by Nicki Arthur on September 9th, 2014.      0 comments

 
Like all treatments we provide our clients we want the best outcomes for our treatments and Electrolysis is no exception.

For the Electrologist our probes/needles are the tools of our trade and of course one size doesn’t fit all! 

Needle selection is important and most Electrologists have a preference as to what they like to use.

Many times on critiquing therapists in clinic I have found only one size needle being used for all Electrology clientele. When this is the case then the endpoint for clients will not always be advantageous. Why is this? As we know clients present with a variety of hair types- Vellus, Accelerated Vellus and Terminal growth, as an example  using a size 2 needle on a terminal hair causes a narrow heating pattern and misses the area of influence by ineffective current on the papilla.

And the opposite is true of the larger diameter needle such as a size 3 or 4 which allows a wider heating pattern. If treating a Vellus hair the potential is to over treat the papilla, follicle and possibly the epidermis.
What are the criteria for selection of needles?

Your guide to correct probe selection is to match the size of the needle to the size of the hairs being treated.
Adjust the needle size over time as the hairs change from stronger hair to finer growth.  Take the time to pause during treatment to change the probe if need be.  This will ensure best practice every treatment.

Guide to needle sizes:
  • Size 2 smallest diameter for very fine hair
  • Size 3 Accelerated Vellus
  • Size 4, 5 and 6 ideal for thick hair
  • Size 10 and 12 ideal for advanced electrolysis treatment.
Most Electrologists use one- piece stainless steel probes as these provide less chance of inaccurate probing and will bend if meeting any resistance.  Two-piece needles offer even greater flexibility as they flex if they meet any resistance allowing the Electrologist to adjust the probe angle.

Insulated needles are manufactured from stainless steel, they have a Teflon or Silicon insulating material leaving the tip of the needle exposed. The current is targeted to the needle tip making the heating pattern concentrated at that point.  The insulation of the needle ensures less surface erythema because current is directed to the tip of the needle. Insulated needles can cause less discomfort for some clients. and a lower current intensity is required.  High frequency is the recommended current. Higher Fitzpatrick skin types can be treated due to less likelihood of hyper or hypo pigmentation of the skin.

Gold needles are made from medical grade stainless steel with a  24 carat gold plating from the shank to the tip. This has the benefits of reduced skin irritation and is  good for clients who redden after a few insertions or have an allergy to nickel.

Gold is a more efficient conductor than stainless steel so levels of current can be reduced, another advantage for sensitive skin or for a client with less tolerance to treatment.

In conclusion be prepared for your Electrolysis treatment, ensure you have a selection of needle sizes, and needle types, assess the area of growth before you begin so your client, whether new to electrolysis or a regular will have the best outcome possible.
