Faith In Nature shampoo?

Had my dreads for about a month now and I was advised that until I could get my hands on some proper dread shampoo (I've ordered Dollylocks), that Faith In Nature would be okay. I wanted the tea tree one but my health shop only stocked the blueberry one. These are the ingredients: 

Aqua (Water), Ammonium laureth sulfate, Maris sal (Sea salt), Cocamidopropyl betaine, Polysorbate 20, Vaccinium angustifolium (blueberry) fruit extract, Glycerin, Parfum (Fragrance), Anthocyanins, Sodium benzoate, Potassium sorbate, Citric acid.

Obviously this isn't permanent but are there any ingredients that seem harmful? Luckily I'm only a month in and my t&r sections are pretty loose so rinsing hasn't been too bad. I think the sea salt though is causing the back dreads (older ones) to lock faster, my hair is super knotty after a wash and some of them are knotting towards the roots. 

avoiud sulphates the sea salts good i dont know how they call that dfaith in nature yet having no faith in nature

the absolute best the ones most recomended is www.dreadlockshampoo.com not dollylocks they are the most natural you can get, the liquid has sea sat and makes em dread fast

the bars  are super healthy for mature dreads

just compare the ingredients

faith in natures surely not great a wash or 2 wont be horible

if u could id recomend ordering these and canceling dolly  you'll have them before your very next wash
