Pilosocereus leucocephalus (Old man cactus).
Yes it’s a plant, not a wig hanging or a dog’s hair, but we had to take a double look just to make sure. 
Pilosocereus leucocephalus, commonly known as Old man cactus (along with a number of similar species), old man of Mexico, tuno, and woolly torch, is a species of cactus in the genus Pilosocereus. This species, native to Mexico and Central America, is a tree-like cactus that can reach between 2 – 6 m tall. The ribbed stem is tufted in thick silky wool and at the top short, funnel-shaped, flesh-coloured blooms emerge, which bear a very strong, foul smell. This species comes from the coastal plain of Tamaulipas state in eastern Mexico, and also can be found growing in Guatemala and Honduras.Pilosocereus is a genus of around 50 species of columnar cactis that spreads from Mexico and West Indies down to northern South America. They are mostly large columnar cacti. The name Pilosocereus comes from the Latine for ‘hairy Cereus’.
