Thanks a lot for the reply. I just couldnt find a way to convert dosages from Bima to Lata, but the eyelashes comparision makes perfect sense. Im definetely upping my dose to 0.1%!The concentration is what matters most not the volume. The volume just needs to be enough to saturate the follicle, whether it's one drop or a thousand drops, you're still getting a .1% concentration at the follicle. Bimatoprost sold as Latisse for eyelashes has a concentration of .03%, that's six times higher than latanoprost's eyelash solution. The minimum dosage Allergan used for bimatoprost in phase II for Androgenetic Alopecia is 1%. So that would be equivalent to .167% latanoprost if you go by their respective effective concentrations on eyelashes. So according to Allergan you should use at least .1% latanoprost for Androgenetic Alopecia, or are they also blindly quoting an irrelevant study?
The person you referred to is probably a hypochondriac experiencing nocebo, or he had something completely unrelated happen and blamed it on latanoprost out of fear.
