Being a seasoned traveller I have separated the essentials from the non essentials. My argument this time is against shampoo and hair washing. So now it is mid July 2011, the last time I washed my hair was April 2010. I found shampoo an unessential item to carry, and the small amount of weight it excludes from my backpack is greater than it seems. As I started excluding items the total weight increases. Ok so some may think that a few kilograms is no big deal but when you are in the middle of Honduras or Bosnia in the middle of summer sweating profusely with your shoulders aching from the weight and your feet feeling like they are about to give way the few kilograms starts to take its toll.
So before I travel again I will exclude the non essential items, shampoo included, and when you see me, or another traveller like me walking along with a bounce in our step remember about those few extra kilograms you packed and discard the shampoo, you will be all the better for it.
