How to wash hair less often and stretch out the washes -- the brush is to help

  I'm changing my hair routine. In with a natural bristle brush 'Dessange' and massage with fingers. Now to washing every four or five days. This brush is not a boar brush but a brush with natural silk brisles. It helps to distribute the oils from the scalp on the length and ends, cleans a bit and really helps to wash hair less often. It adds some volume and fluffiness as well.
  I'm also thinking alternatives for dry hair cleaning, like natural wash rags, natural fabric, cotton wool.
