Nature's Paradise Shampoo Tropical Kids - 16 Ounce

I don't know how different children's hair is from adult hair, but I purchased this shampoo for myself (36 yrs old) because it was one of only two shampoos on the market that got a 10.0 rating from goodguide.com (after double-checking the actual ingredients on each brand's website), and which does not contain any phenoxyethanol, sulfates, or extracts that are considered "hazardous" during pregnancy (such as horsetail).Unfortunately, I followed the instructions perfectly, I've been using this for about one week, and the results have been disastrous. No matter how much product I use or how well I try to rinse it out afterwards, my hair never feels "clean," and I'm inevitably left with very greasy, clumpy, weighed-down hair that does not look or feel healthy or attractive at all. I've never had this problem before--even while pregnant, though using regular/"unhealthy" shampoos--and I don't use any other products on my hair.I appreciate the safety of this shampoo, but it's just not worth it if it doesn't do its job.
