This corn starch based dry shampoo comes in 3 shades - light, medium (for light to medium brunettes) and dark. The dispenser is a smallish powder shaker tube. I purchased on sale at SDM for 13 dollars, regular price 19. I actually went back for a 2nd can after testing it out. I can see this working out for travelling, but I'd store in a zip lock just to prevent spills anyway. I think the amount of product for the price is decent even at full price.
The tone I got was medium, as I have medium golden brown hair, maybe about 5% silver grey peeking through. I sprinkled a small amount in my palm and worked it through my hair and scalp as per instructions and it really did work quite well for me. It didn't make my hair dull and blended seamlessly. I've tried a few aerosol dry shampoos without much luck. I mean I liked the Klorane one, but my skin and scalp hate isopropyl myristate. I did try a few variations on DIY powder dry shampoos but they all made my hair dull or chalky looking.
This is the 1st dry shampoo I have really liked. It is fragranced and doesn't seem to bother my skin any. The scent is not overwhelming, but is gourmand. Not sickly sweet, but sweet. It smells like sugar cookies to me. With a little cocoa and spice. I'm not an overly gourmand scent lover but I do adore vanilla scents, and this smells kind of like Demeter Sugar Cookie to me, but better. I usually use dry shampoo the day before I plan to wash my hair, but with this, if I had to, I could stretch another day out of it.
