ok weird but as a waste-not-want-not kind of person, I can see it might be worth a try for a hoarder attempting to reform....
But this bit: "could be useful if you use mayonnaise as hair conditioner" is just beyond weird. Mayonnaise trashes hair. Great for killing its, but trashes hair.
but I googled it and lo and behold it's seen as a legit treatment for moisturizing hair. really? Oh well.........
