I like the Sexy Hair line. And when traveling I want to be able to take small sizes of my favorite hair products. To be sure, this little bottle IS the full size. And it is not a powder hair shampoo. Quite the opposite, I find that it leaves my hair feeling heavy. There is no way to dispense just a bit at a time so good luck not going through the entire bottle in no time. There is really no way to disperse the product evenly so "play" is a great adjective to describe the product because it might take a lot of play time to create even a simple acceptable style. It left my hair feeling very gunky and with no movement. Most powders will dull shine so even though it is supposed to volumize I didn't want this on my roots. It actually made my hair feel dirty and second day hair is just about impossible if you use this product. Be prepared to wash your hair after using this product. If you are looking for a great updo that is only necessary for one day, this might work because you don't have to worry about looking at lank, styleless hair.
