I shower at work

Before you start - when you're getting ready in the morning carry around a notepad - takes a little extra time, but write down everything you use when getting ready
It makes a huge difference when you start showering at work, it meant that I was comfortable and knew that everything I could possibly need was at my fingertips

My kit is almost identical to what I would take if I was to go camping or travelling

I'm lucky in that we have lockers - but I have a weeks worth of suits and shirts - I get them drycleaned probably once a fortnight (I wear most clothes at least twice before a dryclean.. as long as it doesn't smell or look dirty it'll get pulled out again)

My hair is middle length around my ears, and curly, I rinse my hair at work if I've worked really hard getting in and let it dry while I eat, or I brush it out when I get in - I don't worry about shampooing in the mornings at all
One of the ladies who used to ride in has a hair dryer in her drawer which is at anyone's disposal - but I've never had the need to use it

What do you normally do with your hair? If you would normally say - use a straightener - Grab a second one for work and leave it there
Or if you coif and pin and make like a peacock - then make sure you've got the kit and the time to do it as you would normally
Or.. If you throw your hair into a ponytail - make sure you've got elastic and a brush
