Review (5/5): Fabulous volume for the first day, cannot tell much difference in volume after a couple of days
This stuff gives great volume in the 24 hours after you use it! I can't tell how long I get a bit of extra volume with it. I have used it with the L'Oreal volume filler shampoo/conditioner and with others, and it seems to work fine with all of them. I wish it gave a lot of volume for longer, but this is my go to before events.
