I have both caboki (same thing as toppik) and derm match.
Often I blend the two.
Kaboki and Toppik come in containers that shake out like salt and pepper . But instead of putting it on your dinner, you put the Kaboki on your hair.
The Kaboki stays in better with hairspray. Instead of shaking off your head like dandruff,its much better to put a little hairspray to keep it on. It says on until you wash it off, even when sleeping.
Derm match is something you paint onto your hair. It thickens each hair and paints your scalp the color of your hair. So instead of using hairspray for the Kaboki to keep it on, I use the derm match.
Thus i dont have to use much of each and they work in tandem. The stuff really does work!!!
