Queen Helene Hot Oil treatments have been on the market for many years. They don't have the glitz and flash of modern packaging or the slick-magazine-ad style of similar products that charge an arm and a leg. But they are excellent! I have used this hot oil treatment many times and it leaves my hair smooth, de-tangled, and healthy-looking without weighing it down. Because my hair is fine, that's important. Queen Helene never leaves a heavy residue or buildup. It just restores the hair leaving it shiny and smooth. The results last for about ten days, which is great compared to other products true lasting-time (not their claims). Effectiveness Does just what it says-- leaves hair healthy and infused with moisture without oiliness. Scent The scent is very neutral, without any heavy perfumes or lasting smell. That's my preference, as I don't want a deep conditioner smell added to every other fragrance-containing product (deodorant, hairspray, etc.). The oil has a clean, natural scent that I like a lot.
