The “treatment” level of energy does not extend very far above the uninsulated portion of the tip Deanna, only 10 percent of that level is released to the upper root sheath. The upper sheath does not want to “give up” as it were, but that is not the true anchor point. That is taken care of down in the target area below.
This is why it is very important to understand the Kelly tip concept. While the Kelly tips have shown suprising pain reductions for shallow insertions, they are not intended for deep hairs like Dee’s pic above. A full length standard tip is appropriate to get a good release with these deeper hairs. When the deeper ones are the exception instead of the rule, one can deal with them by displacing and firing again when the shorter Kelly tip is used.
