I did this trial for 3 months after a month long bushwalking trip got me through the worst period. But TBH with fine fairly straight hair it looked pretty average on me, to the point one of my GF just straight up told me it was pretty awful. I now only use natural shampoos and conditioners and only wash every 3 days (my hair copes fine) but I rinse it every day. You can find products with:
  • no sodium lauryl suplhate
  • no petrochemicals
  • no artificial fragrances
  • no harsh detergents
  • no animal products or derivatives
  • no harmful chemical and
  • no parabens.

which are very gentle and do the trick if you want to take a different path.

My friend who has thick red, curly, frizzy hair loves the 'no poo'' technique and her hair looks great.
