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.
I'm either imagining things or Oshima Tsubaki Oil Shampoo just really sucked, because my hair is much lighter and less oily now when I'm using this shampoo. I was a bit nervous with the supposedly "tropical" fragrance that's "fruity neroli," but it turns out pretty pleasant and not as hippy as I'd imagined ^.^ Being SLS free but this shampoo lathers really well and rinses well, and it keeps my hair nice and soft all day! Will definitely try more shampoos like this!
Freebie samples that came with the purchase, and I'm especially keen to try the Scalp Cleansing Gel (bottom), which is supposed to be a warming clarifying shampoo.
