Heard nothing but good about it, nothing on the negative end.
There was no direction label with the Nizoral? If it was an Rx the pharmacy should have it labeled on the box or bottle itself telling you how often to use it. however if it was not labeled than I suggest that for hair loss it be used 3 times a week, prob on mon/wed/fri or mon/wed/sat routine. This will break it up so as though you are not using it every day constantly as there is the possibility of the side effect where the first few applications may cause headache or some hair shedding.
