I came across some information that states that the thermolysis method is not meant for coarse hairs, and that it can in fact cause skin damage if used on coarse hairs (Damage which may not even become apparent until upwards of 15 years afterwards!). My electrologist has been doing this method on my female unwanted facial hair, and now I fear I may have long term damage...
To top it off, this source claims that "With thermolysis, we find that with each pass, we remove the main hair, but stimulate follicle sites surrounding the original offender. The skin, does what it does best, and that is to protect itself against stimulation and one of those mechanisms for protection is…(good grief)…HAIR. Often the harder you work, the more there is to do!!!" source: http://hairzapper.com/thermolysis/
I have noticed this exact thing happening to me, I have hairs that DID NOT exist prior to beginning electrolysis/thermolysis...which means it would just be a never ending cycle if I continue with my electrologist who operates in this mode.
What are your opinions on this?
