I used this yesterday and here is the verdict:
It's mildly clarifying ie does not strip your hair, but cleans it with very little suds.
(which is not suprising considering it contains neither sls nor it's close relatives,but if you want suds, then this is not for you.
The reason the majority of shampoos use sls is because it's a cheap foamer and a very strong detergent used to degrease car engines. It does not have a nice track record, but I won't go into that today).
The smell is ok - just a bit of peppermint.
The downside is - I had to use a lot of it. I did dilute it as always, but the amount I used before I felt I was getting somewhere means it's not as economical as I thought.
However, this is a loc friendly shampoo, so if you ran out of sisterlocks starter shampoo, dreadhead HQ, or whatever shampoo you use, this will be a good substitute.
