"Transitional" breakage question

My question is: About how long should this "transitional" breakage period last? (I mean the transition from unhealthy to healthy)

My hair is about 1/2 inch from armpit length, but it is a little stringy and "see thru" from me not taking very good care of it over the years ... So I am now on a "healthy & thick" hair care regimen (on it now for about 3 weeks)...  But I am noticing breakage - and it was doing GREAT the first week of my regimen (I did a mini-trim in Aug.). As my hair is going from unhealthy to healthy, I am seeing those little pieces coming off.  I know it is not something I am doing wrong now, because I am using the right products and doing the right things.  But it seems that it is now doing the same as when I was not taking care of it.  I do not get clumps of hair coming out like I used to, but I don't want to see ANY hair coming out now that I am taking better care of it. 

***I plan to do mini-trims (1/4 inch) every six weeks, until February to try to banish some of the stringy-ness. And then I will not do any more trims for the rest of 2006 and just keep the ends conditioned and moisturized.

I did the Aphogee treatment 2 weeks ago... And it worked great!  But should I use it everytime I notice breakage?  I notice some people space the treaments out like every 4-6 weeks.  I also do the baggie thing once a week and I use leave in cond. and Kera Care Essential Oils or their Oil Moisturizer everyday.
