The sulphate-free poos I have tried, like most people here, I have found really drying on my hair, much more so then normal shampoos, so generally I would go for a gentle poo every so often. Its weird how the 'natural' shampoos seem to strip hair more.

However I have finally found some completely natural shampoos that really do clean my hair without stripping it or ruining the curl- the Chagrin Valley shampoo bars. So for me I will be using these from now on with the very occassional normal shampoo if needed.
