Re: what to do with the hair after the wedding?
I dont remember my hair being a mess after my rukhsati but the nikah one was a different story. I actually didnt take out the pins after my nikah and slept like that. The next morning, the hair style was still in place, thanks to all the hairspray.
Like SGC said, you are mostly just so tired that the thought of a shower is too overwhelming. Just smooth it out as much as you can and shower and blow dry in the morning.
