Truly "Soap free" natural shampoo - recommendations please

[Taoist]

Hi,

I have been looking looking for a soap free emollient based shampoo. So far I have come across a lot of so called Sulfate or SLS free shampoo's but when I look at the ingredients they still contain some kind of related soap(or detergent I should say) like chemical like sodium cocoate or laurate or something similar.

I have had some success with Aquanil which main ingredients include water and glycerin but there is a small amount of SLS and it seems my scalp psoriasis simply cannot tolerate any amount of any detergent like substance.

Any suggestions appreciated.
