Salt-free shampoo recommendations needed please!

[SoftKittyWarmKitty]

I use a keratin treatment on my hair every 12 weeks, so need a salt-free shampoo. I usually use the Naked range of shampoos and conditioners from Boots but I'm about to run out and they don't have the one I use in stock locally or online. I go on holiday in a few days, so I'm looking for an alternative that I can buy on the high street in the next day or two. I've spent ages googling but they all seem to have sodium in the ingredients. Does anyone have any suggestions, please?

I use this and it's really good for my greasy hair and itchy scalp. It doesn't seem to have any sodium in the ingredients

Oh, sorry, just saw you're going on holiday soon. Sorry

The L'oreal Everpure range is probably the most readily available if you're in a rush.

I think the Everpure range has sodium in the ingredients as I remember looking before, but I'll double check.

Lush curly wurly shampoo appears to be salt free.

Thanks Dynomite, I'll consider that next time when I'm not in such a rush .

I found a load of naked products in 99p World if you've got a local one?

99p World? Never heard of that but I'll have a Google and see if there's one nearby, thanks.
