Hi James,
One thing that I would like to relate in regards to the Kobayashi-Yamada technique is that one can also perform a modified version of this with hairs up through late telogen.
As the hair moves up the follicle, it will rise quicker than the root sheath will retract behind it. As the telogen hairs will develop the tiny little ball of collagen at their ends as they leave the moisure-rich area of the follicle, this will be some distance above the lower portion of the follicle at that point in the shedding process.
A modified version of the Kobayashi-Yamada technique is to use 2-pulse thermolysis and progressive movement. The first pulse will dislodge the collagen ball on a late-stage telogen hair and allow the probe to slide down the remainder of the follicle with little to no resistance. At this point the second pulse will occur, frequently eliminating the regenerative tissues of the papilla and most likely the bulge area as well. Remember that the retracting remnants of the dermal pappila are not that far away from the bottom of the old root sheath and at the deepest point of the moisture gradient for that particular hair as well.
One note here: This does require very good insertions and the proper amount of power to be effective. Even so, I would have to admit that some of this is speculative and anecdotal at this point, although I have heard that there are clinical investigations under way in this area. (Japan and Canada were what I’ve been told, although I really haven’t checked up on this.)
Notice that the major difference to this approach is that there is no penetration of the bottom of the hair follicle and it is a much less invasive method of treatment than the original Kobayashi-Yamada method.
Just some thoughts on a subject that was presented to me as a student. I have also been told that this does work better with finer, shallower hair than with deeper, coarser hairs.
Like everything else in this field, there are many variations in the way that the art portion of this “science” is practiced. I will be interested to see the final statistical evaluation of this modified technique as it becomes available.
All the best,
