Using this 600mL bottle of Cocopalm Natural Shampoo right now and liking it quite a bit! Since using Tsubaki Oil Nouveau 2015 Shampoo, I've been seeking out the non-silicone instead of regular shampoos. This Cocopalm fits the bill. It's advertised as "amino acid and non-silicone," and also free of sodium laureth sulfate, paraben, mineral oil, and additives. According to Cocopalm's brand website, the shampoo also has hibiscus and papaya essence.
