In cutting your hair, you make a statement that you will no longer abuse your nature with chemicals which you can find in shampoos, conditioners, dyes and other hair products. We daily pollute water with products for hair just because we want to look good, nice and attractive with beautiful shiny hair. By shaving it all off you simply say that you do not allow this in your world anymore. Another perspective is also that you let go of your ego because hair is something that most people see as a sexual object. In an equal money system you will not have to be bald. It is your choice. But there will no longer be such abuse of our nature, because shampoos and other hair products will be made without chemicals that could contaminate water and generally nature.
