OK - so not easy at your average festival, but not impossible either - although there are usually some washing facilities somewhere they won't be the best - try taking a bowl to fill with water from the taps. Better still take a water container - you can find some cheap collapsible containers with taps that are just right for this situation - fill it up in advance and you have instant personal washing facilities.
Wet wipes are a good standby for hands before and after eating, and absolutely essential for those dodgy toilet moments! personal hygiene is absolutely essential at a festival which - let's face it - is a prime breeding ground for nasty little germs. You can ger some great spray deodorisers that will fit neatly into your pocket too!
Girls - sods law says that your period will start just in time for that festival weekend - make sure you take enough tampons with you - and wet wipes (unperfumed of course!) - will be indispensable for use both before and after that loo visit. Make sure you've got some pain killers on you if you're prone to cramps - just don't take too many and be wary of mixing with alcohol.
Deodorant is essential and perfume can mask a multitude of sins! Hair washing is just too difficult - theoretically it could be done under a tap but to be honest it's just not a good idea - get your hair as you want it before you go (dreads, plaits and extensions will get you through brilliantly) otherwise take a hat or scarf to tie fetchingly and create your own individual look! - as far as fashion goes absolutely anything goes at a festival and you can get away with crafting your hair in ways you'd never dream of in any other situation - so have fun with it and don't stress.
Don't forget your toothbrush! - just don't okay - all that excess will leave your mouth feeling like the inside of a festie toilet - you will so need to brush your teeth! Chewing gum might help but it only helps so much.
If it rains it will get wet and muddy - so will you! - there is nothing you can do about it so just accept it - just make sure you've packed a spare set of clothes to get you home.
Don't forget to take a towel!
