What is the thermolysis method?
Thermolysis uses alternating current to heat your hair follicles in order to destroy them. It is faster than the galvanic method but may require more sessions since more hairs will survive the procedure. As far as Hairchick can tell, this basically destroys the time-saving benefit. Thermolysis was first widely used in the 1940s and many salons still use it. This method is not great for coarse hairs (such as those on the bikini line) and some experts have suggested that thermolysis electrolysis carries with it a slightly higher risk of skin damage.
What is the galvanic method?
The galvanic method uses direct current which reacts with the body’s chemistry and creates a chemical reaction at the site of the hair follicle, killing the hair. This was the first electrolysis practice used and it is still used in some salons today. The galvanic method destroys more hair than the thermolysis method, requiring fewer repeat sessions. In most salons today, you will find that several needles are applied to the skin at once with this process to make the waiting time more bearable. In galvanic electrolysis, the current reacts with the high salt water content of hair follicles and chemically destroys the hair. The problem is that it takes about two minutes for each hair to be destroyed!
What does the blend method involve?
As you can likely tell from its name, the blend method combines the two types of electrolysis (thermolysis plus galvanic) to make an electrolysis method which most practitioners and experts recommend. This ‘blend’ has now become the most popular one, since it as fast as thermolysis while killing as many hairs as the galvanic method. Blend electrolysis kills hairs chemically (just like galvanic electrolysis) but it takes only a few seconds to kill each hair. It works on coarse hairs and fine hairs equally well. The main drawback is that blend electrolysis involves more pain than thermolysis electrolysis. It is also more complicated than either thermolysis electrolysis or galvanic electrolysis, making it especially important to find a very qualified practitioner who has had plenty of training and practice.
