ch123,
I am very close to getting cleared for the first time so I do not have the direct experience. However, the woman who does electro on me has been doing it for over 20 years and has totally cleared a number of us. There are also some on this site who have been totally cleared so don't loose heart.
Based on what I discussed with my electrologist, there could be two issues: First, my lady wants me back once every three weeks to keep moving forward. I will keep taking less time with each return. Every six or eight weeks may not be frequent enough. Second, some hairs do not come out totally straight. Your electro person may not be getting to the root if they are not very attentive to your pattern.
Hugs,
Jen
