My hair loves them as well, and my dryness issues are a thing of the past. The mineral oil thing.... now I don't like vaseline(capilo products) on my hair, but keracare humecto, and other salon quality american products contain mineral oil in similar proportions sometimes. It depends on the individual conditioner's ingredients. There are some that don't contain mineral oil/petroleum products as well. The ingredients are not that complicated to me(maybe because I majored in chemistry), but still there are many sites that will give you information on these ingredients and their use. In the end dominican products are hit or miss, like anything else. Either they work for you, or they don't. I am glad they did for me, because after using Keracare products exclusively for two years, after a while they just stopped giving me the same results. I do know that when I was natural, I avoided mineral oil like the plague, so I wonder would I still have had the same results.
