Do you tie it in a knot?
Do you tie it in a bow?
Do you take advantage of the steam, and put it up in rollers?
I do the rollers, unless I want to lay back and soak. Then, I’ll pile it on top of my head with a hairclip.
I wash it at the end of the bath.
If it’s just a recreational bath, I put it in a bun at the top of my head with a chopstick thingie through it.
I start with the bun, but I’ll usually relax so much (or my neck will get stiff) that I’ll sink in and my hair gets wet and I have to wash it anyway.
Now, in the shower, I wear a showercap. Looks ridiculous.
I rarely take a bath. My last *bath ** was in excess of 3 years ago.
But when I last did, I put it in a bun.
*Yes, I take daily showers.
If I were a long haired woman, I would throw it over my shoulder like a continental soldier.
But then when it starts wobbling to and fro, you’re screwed. Trust me.
I usually put mine up in Heidi braids until I need to wash it. The way I do it is much less involved than the link. I just braid my hair in pigtails and then clip the braids in place with the flat metal snappy barrettes. The braids are just long enough to go from ear to ear.
i braid it then pin it up … although i don’t take baths frequently*. usually only when i travel and the hotel has a jacuzzi. 
- i wash it every day in the shower.
I almost always have my hair in a ponytail anyway; I just take that and clip it up on top of my head.
Just lift it all up very roughly and use a buterfly clip to secure it - ends up looking all sexy and tousled if a male comes in the room, AND is practical and kept out of the water if not! 
should you like baths on the hot side and a bit of bath oil, you’ve got the making of a hot oil treatment for your hair.
i would just leave my hair down. from about top of shoulder length down it would be in the water. perfect placement for hot oil treatment. just shampoo and condition after.
add in chocolate, a beverage, and book, and i’m in multi-tasking bath heaven!
Similar to Sensibility, I just grab it and twist it, and pile it all up on top of my head securing it with a butterfly clip, although sometimes my hair will take two butterfly clips. My hair’s texture is very fine, so it gets all slithery when the humidity makes it straighten out. I’ve trimmed my hair considerably since the spring, and I’m down to just about two feet of hair instead of three. It’s much easier to keep it from tangling around me in the bath or bed, now.
Nothing. I shower as well.
When I did take baths, I still did nothing (except accept that my hair would get wet). Shower caps feel stupid, and I have yet to be able to find a way to put my hair up in a way that would both stay and feel comfortable for the duration of a bath.
Then I discovered that it’s easier to just wash my hair with the rest of me, so now I don’t care if it gets wet when I wash.
I’m a tub bath kind of girl! Soaking in a warm bath with a good book is almost a daily requirement for me. If I’m going to wash it, I just leave it down. I’m trying to break myself of the habit of washing it every day - as I get older, it gets drier so unless it’s dirty I leave it on top of my head in a butterfly clip.
Remember when you were little and you’d swish around underwater so your hair would slowly float about you, all mermaid-like?
I still do that.
I twist it up into a roll and stick a pen through it. It’s sort of like when you do a french roll except that instead of using pins, you take a pen or pencil and sort of weave it through. I don’t know how it works. I think it has to do with the power of tangles.
What she said.
My hair is a bit longer than three feet as of the last trim. I get the spring clips with teeth like combs, pull my hair up in my hands as if I were going to put it in a ponytail. Then I twist it and then roll the twist into a doughnut, then I pull the top loop down over the rest, and clip it where the tail ends, leaving a chunk of tail loose to look cute. Actually, it’s also one of my daily hairstyles, no product, and easy to repair.
That was damn funny.
My hair is over 40" long… I wear it up in a knot almost every day, so when I want to take a bath, I just leave it that way.
I use a pony-tail holder to pull mine up into a loop, or I’ll put it into a knot on top of my head with a chopstick through it. I like to think the former gives me a sort of Gibson Girl look
