I’ve been washing my hair with only water for about 3/4 months now,
and I like it : ).
My hair isn’t as greasy as it was before.
I’m able to not wash my hair for 3 weeks without anyone realising it.
(I usually wash my hair every two/three weeks.)
The only downside is that I do see sometimes little white flakes on my hair, but with some brushing they go away (I don’t know if I used to have them before I started no poo, before I wasn’t really much fixed on my hair).
Sometimes my head itches a little bit, but at the other end… I don’t have to put any chemicals on my skin, and save a lot of money. For me the good things outweigh the downsides. So I’m going to continue living without shampoo : ).
