You just gave me a great idea!
Put the hair in cheesecloth, panty hose, what have you, but I'd soak the whole mess in deer repellant spray first, and hang it from your fence or a post. I don't eat egg yolks, whites only, but I use the yolks in a really nasty spray.
Use 3 eggs or 5 yolks (or 6, whatever), and at least 3 cloves of garlic. Add a tbs of
milk (I just use a tbs of dried milk as we don't do
dairy), a probiotic capsule (helps speed up fermentation), and do it up in a blender with a cup or two of
water. The milk is just to make it stick to the plant, so I guess you could use liquid dish soap, a few drops or so. Toss the mess into a gallon jug, fill to the top with water. Let that mess sit a month, or till it stinks to high heaven. Strain out the solids with muslin or cheesecloth. Add the leftover solids to your hair mess. Put the strained stuff in a sprayer, spray your trunks and your fence perimeter.
Don't use it on fruit
trees while they're blossoming or in fruit. I generally just spray the bottom of the trunks, and the area around your fence. It only reeks like h*** for a day, but the deer and elk can smell it for weeks.
It's the same stuff that Home Depot sells for a stupid amount of money, but if you have
chickens and raise your own garlic, it's pretty cheap. It smells really disgusting til it dries, but it really works. Deer and elk hate it. Make sure you aren't downwind when you spray it (or you'll need an immediate
shower after), and tell the dogs to go find someplace else to be. You can add cayenne to it if you want. I don't, cause I've killed plants with that stuff, so I don't use it.
The only other thing I know what to do with a glob of hair is to cut it in little pieces, and add it to your garden soil for really slow release nitrogen.
