According to About.com, Coconut Cream Natural relaxer contains some natural ingredients that are not as harsh on hair as lye, which is used in conventional relaxers. No product that can straighten curly, textured hair permanently is completely herbal or natural. There are only relaxers that contain some herbal ingredients.
Products that claim to be completely herbal or natural are actually temporary deep-conditioning treatments, which make very curly hair easier to manage. Hair still needs to be heat-styled after applying these type of treatments though. When the hair is shampooed, the effects of the relaxer are gone and the hair goes back to its previous curly state.
