Water-washing hair in between

  I doubt that I will be able to wash my hair less often. So now I wash once a week. And recently I've done some in-between water sprinkling: hair becomes sleeker and lighter in colour as the dirt goes off  with the mechanical action of drushing damp hair. I am afraid to wash more often than once in six days (that may make hair get greasy more quickly. Now two days is the norm of good hair.)
  Сомневаюсь в том, что смогу мыть голову реже, чем раз в неделю. Мою раз в неделю, а чаще, чем раз в шесть дней, также опасаюсь, потому что тогда волосу могут жирниться быстрее. Сейчас обычно два дня хорошие волосы. Последние две недели брызгала водой на неделе: тогда часть грязи сходит на расческу в процессе причесывания влажных, волосы становятся более гладкими и светлыми.

Tips from an experienced no-pooer

  How often should you wash your hair? When is the time? What are thw signals? Here  is the piece of advice I've been given recently in a  no-poo community.
 'As for training your scalp, for me, i just wouldn't pay attention to how long I would go between washing it. I'd only wash it when my scalp felt itchy, or my length felt waxy. I wouldn't wash it just for the sake of washing it. I hope that helps.'
  As for my scalp fels a bit itchy abouth the fouth day. The hair starts being waxy later.
  'That's absolutely reasonable. I've been no 'poo for many years, and I still wash my hair about once a week.'
  So now I wash once in 6-7 days. Hair is fine for about 2,5-3 days.That's very good, 'cause when I washed more often, it was not very fresh about the end of the second day. Perhaps cold autumn weather helps, too.

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.
