I live in the Uk and I understand how electrolysis works. in the UK most electrologists tend to use the thermo strategy. I am a female who has hirsutism and my excess hair is quite thick and long. I want to have electrolysis done and have found a professional electrologist in my area however she uses the thermolysis method. I want to go get it done but what is the point if at the end of the day I’m just going to be wasting my time and money. I feel like there is no hope and to be quite honest, my current situation is making me feel so depressed right now. 
Any of the three methods (galvanic, thermolysis and blend) will work fine on thicker hair - it’s just a matter of adapting the chosen method to the needs of that hair.
Hi cheryicheri. I hope you are seeing positive results from your treatment. Just as EmancipatedElect says, thermolysis will work on fine hair. I hope that you will let us know about your progress.
Just make sure that the hairs slide out.
