It absolutely does unblock hairs. That's literally what it's designed to do. We're talking about the same product here, yes? It's not Mr muscle spray. It's not a spray of any kind. It's a thick gel that you must NEVER get on your skin or clothes, even a single drop. It's extremely dangerous. You should look up those people who were killed in America by some madman serial killer, he handcuffed a bunch of people to radiators, and then forced them to drink Draino, which is the same thing as Mr Muscle sink unblocker. Same ingredients, everything, just a different brand. I think one of those people who drank it survived, but they can't eat anymore, they have to ingest food via an IV hooked up to his arm. It was in a documentary I watched, I think a BBC one. Anyway yeah, it burns and dissolves everything (well everything except your sink and pipes obviously). It dissolves food into nothingness, which is why it's used as a kitchen sink unblocker to eat through all that food so it washes away instantly. And it dissolves hair, and any organic matter. It'll dissolve meat. This is why you don't get it on your skin, you wear rubber gloves when you're pouring it in, and even then you should wash your hands afterwards even though you were wearing gloves, just in case. Basically anything it touches, it dissolves. Except for the things sinks and pipes are made out of. So it won't dissolve plastic for example. Which is annoying because I managed to clog a sink with lots of tiny bits of plastic once, and of course the Mr muscle sink unblocker couldn't help with that. But it always helps for any organic matter, it dissolves it into a thin liquid that then can be simply washed away by turning on the tap for a minute or two. So all food is, of course, organic matter, meat, vegetables, everything. So is anything alive. This is why if you have dogs or cats for example, you have to be incredibly careful to not let them in the room that has the blocked sink. You lock the door, let nobody in, as you leave the Mr muscle in overnight. Then you wash it away in the morning. Cats and dogs like to drink from dripping taps and toilets and anything like that. But if they touched Mr muscle, they'd then lose the thing they touched it with. Like it'll dissolve their paw into nothingness. Or god forbid, their tongue if they licked it, you'd have to feed them via syringe or something for the rest of their life if they managed to lick the sink unblocker. It's a very scary blend of chemicals, that's for sure.
