I got this product on a whim. I have severely dry ends that are frayed at this point. Upon initial use, it seems to have made it a bit smoother (I opted for the overnight treatment option). I read a review that said it smells like peanut butter, and I see the potential. Having that in mind it visually reminds me of pure, organic peanut butter; the color and oiliness along with that faint smell really brings it in together. I love how it’s hard to liquid, easy to pick up product and melt to apply. As someone with sensory sensitivity I despise the texture of the oil, but that is a me thing nothing to complain about the actually product. If you are someone who does not like to touch heavy oils, I recommend you find someone else to apply for you, or maybe an entirely different product. I am desperate enough to deal with it. I just got this last night I will follow up in a few months.
