Yuk! - I'm with Susan - there is a limit to what I'll do to look better......Laker poops on my hand lots of times but I haven't noticed it being beneficial!
I have had bird poop hair additives and facials, I have to say I dont think it works. Peanut rides on my head a few times he does not lean away from me far enough and I get decorated.
I didn't get to see the article, I went for a look but the page must have been updated since you posted.
Getting the jist of it though, birdie poop...ummmm bad enough when you clean the cage and get a gooey one on your hands, immeditaley off to the sink to wash it off. Putting in on my face..I will grow old gracefully thanks.
