'Change the toothbrush when it withered up'
We don’t know the correct service life of the toothbrush because there are no certain change in hair. Do you want to know the correct service life? In nature fresh green grass turns into brown when it withers up. Like this grass after three month of use, you will easily know the time to replace by change of the hair color. Check the grass on your brush.
