IrrenWirr I've been doing no poo for very many years, never any shampoo. No conditioner either. Cold water and scrubbing (probably the same effect Admin was talking about about having to physically press down charged water into the hair so the oils react, water and fat doesn't mix), then max cold water to finish it off. (Then I use a towel to dry some water and spray with bw, scrub again. Don't know how effective it is because things are already wet, but it feels good, is my routine now)
Your hair gets used to it, scalp makes less sebum. Can improve many conditions. There's communities talking about it. Some only use natural conditioner. People with longer or curly hair especially.
But using warm water makes my scalp flake. Maybe it strips too much of the oils out.
So I'm not dipping my head in charged baths anymore, effect was the same. Maybe in the future. Or after it's cooled down to room temp.
