There is wide variation in the number of treatments required to fully heal structures in a given patient.   The variables are the extent of the injury, the strength of response to a given Proliferant solution, and the capacity of the individual’s healing system when maximally stimulated.  Most people can heal most injuries in four to six treatments on average, but some people heal VERY QUICKLY—one or two treatments—and some people heal VERY SLOWLY, needing eight, or ten, or more treatments to heal significant injuries.  We will try different strategies when ‘slower’ responses are noted to improve the pace of healing as much as possible.  But some patients simply have a modest response to any strength stimulus, and there is no arbitrary ‘limit’ to how many treatments may be needed, or given.
