Salt free shampoo recommendations

[Marmaladegin]

I have keratin -straightened my hair at home (treatment works v well for anyone who's interested) but you're supposed to use a salt-free shampoo after... can anyone give me some examples?

Or maybe a chemist could tell me what I need to look out for on the ingredients of shampoo?

I believe the ingredient is listed as sodium chloride. Generally looking for a SLS / paraban free shampoo will do the job. There are many high end and quite a few regular prices versions in boots And Holland and Barrett if you don't want to go down the 'Aveda pure' type route I find faith in nature is a good one

This one from Faith in Nature is sodium chloride free and really nice.

Oh although it does have maris sal (sea salt), not sure if that's a problem.

Well actually I'm an ex-curly girl method follower, so most of my products are Sulfate-free (and love FiN) but I was surprised at how many mention salt in the ingredients
