My last 3 needing sessions have been "heavier" with 8-9 days rest between I really think this has caused an uptick in results. Just food for thought for those who may not be getting anything. Maybe try a heavier type session once or twice a month with more rest. Now when i say "heavy session" i mean this - What i do with My Dr pen is go over my head 3-4 times till redness. Then i repeat that two more times. By the third cycle i'm usually able to draw blood from any area. I usually take a 1 min break between cycles. Yeah there are blood spots all over, but my head is not pooling blood or anything at all, not even close. This is just a bit more intense. My goal is to get back to near full head of hair and then do a heavy type session once a month. Remember there is alot we don't know about this needling thing, in terms of different protocols. Everyone won't react the same. Some may get results from mild redness, some heavier sessions, some from needling more often (chen). Alot of variables.
