The only valid "intermediate verdict" is that as long as no mode of action is known, the likelihood of any positive results whatsoever is very, very low.
I'll probably give LLLT a try some time next year nonetheless, after I've established a stable baseline with finasteride (which I have just started two weeks ago) so I can actually make reliable statements. I expect not to see any results from LLLT (damn, the explanation "energy gets juices flowing" is the most stupid there is - you could also use a light bulb or a heater according to that "explanation"), but I'll do neutral documentation and let others be the judges.
As you've been on it for 5 months now, could you create a photo thread?
