Dr. I bought the hair max laser comb, i cant tell if it is producing results or not, my hair is still pretty thick, my question is, is there a difference in the hair max laser comb compared with the machine that you sit under, is there a difference in quality or the results you can expect?
Unless you have a camera that takes pictures at the exact and repeatable spot on your scalp, it is almost impossible to tell. One researcher (see: Analyzing the Results of the HairMax Laser Comb) used a small tattooed dot on an area of interest and took serial photographs at regular intervals to see if there is a change in hair count. I reviewed that particular study, as you can see in the above unfavorable reference. To my knowledge, no comparable study has been done so far for the lasers that you sit under.
With respect to your question asking if laser comb and the ‘bigger’ laser machines differ, well, the size comparison is obvious — one is a comb and the other is a big hood that you sit under. If you are asking if one is better than the other, I have no way of telling, but based upon the study of the laser comb, which was most unimpressive, I might think that the comb has very limited value. The subjective feedback of patients who have experienced the larger system seems positive, but there are no objective criteria for me to endorse. If you are asking for the results, I have no way of telling at this time.
