was the hair freshly washed? if not, then whatever products you had on your hair must have just been doing their job and keeping your strand sealed
next time, get a shed hair out of the comb after you've washed and clarified but before applying any condish. Let the shed hair totally dry and then do the test again. . . .or just get some shed hair now and wash it with dawn dish detergent(works REALLY well to strip off product) let it dry and then try the test.
