Frankly, I think you are a LUSH associate (like the OP of this thread). I don't appreciate this surreptitious peddling.
If you are in fact a consumer, here is my honest opinion:
Personally, I find LUSH hair products hair products ridiculously expensive. I much prefer Aubrey Organics (also made in small batches, very natural – mostly organic, in fact – and affordable). Oyin Handmade and Shea Moisture deserve a shout-out too IMHO. No sulfates, silicones or parabens in any of these brands. No propylene glycol** either, unlike some LUSH products.
"Research wise Health Canada says they find SLS and SES to be safe when not used on hair alone and when added to shampoos and conditioning oils it is diluted even further and in some cases deemed inactive." – If it's inactive
then why the heck is it in there? That's some nonsense talk. It probably helps cut potential build up of the oils, etc. on the hair, but it's certainly not "deemed inactive."
Both SLS and SCS are derived from coconuts; the difference between them is a matter of purity (similar to distilled water vs hard water). That doesn't mean they aren't stripping. For info into the chemistry of it, see http://longhair.livejournal.com/2356788.html
**Propylene glycol is a cheap and effective humectant, but many people are allergic to it. It took me years to realize that it was the culprit behind the mild rashes on my face and scalp. And it's in the $30 for 8.4oz Retread conditioner – which also has PARABENS?! I'm sure you can find a less irritating, truly natural humectant to put in there – honey, agave nectar, aloe?
UGH – after doing my research to write this response, I'm done even considering LUSH. I am beyond
irked at "natural" products that are not. What a green-washed load of crock.
