Hair loss is possible, but not likely, I don't know of anyone who has experienced it.
I think they just print it on the bottle so it makes the user think the stuff is stronger than it is. Just like how it says not to exceed 3 pills a day, who doesn't do 4 to 6 or more.....

Is this Hair loss minor or major? There are many factors that can go along with side affects, such as Hair loss. A poor diet, lack of sleep, etc..., can lead to minor Hair loss. I dont think it seems to be a major problem but if it persist you need to experiment with getting off 1-AD and see if the side affects persist. If so, get it checked out

if you are prone to MPB, you are more likely to lose hair
