Many wheelchair users know that it is often difficult to wash ones hair when travelling. Even when one uses a so called disabled room or wheelchair accessible room in a hotel it often lacks the right shower chair or doesn't have one at all. Most available shower chairs are too small and don't provide any sitting support to people who don't have a good balance or are floppy as soon as they are out of the wheelchair.
Luckily I came accross a shampoo one can use without needing water. This means that one can wash ones hair while sitting in the wheelchair or, in case someone is very ill, in bed. One doesn't get wet, doesn't need a shower, doesn't need to risk ones life on a unsuitable shower chair, but does get clean and nice smelling hair!
