I live with a guy who has almost no hair. I mean, there are plenty of hair follicles on his head, he just chooses (okay, he's in the army, so his choices are limited) not to take much advantage of them.
But Thor and Tess both have long hair. (And I can't find a photo of either of them at the mo showing their long hair. You will just have to take my word for it.) Tess's hair is pretty much to her waist, and Thor's is halfway down his back.
Aside from having to help them brush it out occasionally, because not only is it long, but it is a mixture of coarse and fine hair, so it tangles easily...
I also hate long hair because it is EVERYWHERE. Doing laundry I pick long hairs off the clothes as I dump them in the laundry and more long hairs off the clothes as I fold them.
Then there is the vacuum cleaner. I love my vacuum cleaner except for one thing...the carpet brush is hard to get off and back on again. But every couple of weeks, the brush gets so full of long hair it no longer works properly.
So I must disassemble and cut the hair off (hair is tough. I use a steak knife to saw through it -- and yes, it is dedicated to stuff like that. I don't toss it back into the scary drawer. [The scary drawer is the one full of sharp and pointy knives. We didn't use to have a knife block in it, but now it's not quite as scary. ]).
On their heads, it's gorgeous. Thor's is a coppery red and really really thick. Tess's is brown under and has a deep hint of red on the top layers. She used to be a blond blondie, but it is gradually getting darker. I think eventually she will have brown hair with some seriously nice coppery highlights. Like mine, only better. Mine is mostly just brown.
