Very versatile, easy to apply, super easy to wash out, probably the best product I've used and I have used plenty, with previous fave being American Barber (Red).
The best part is can apply Imperial on wet or dry hair and with both can then (after it dries) run your hand through the hair, which the girlfriend loves, and not have it become sticky (assuming you have dry hands).
I have thick hair with lots of body.
I've tried a bunch of water based product, and the Imperial is by far the best. Easy to apply & reactivate with a little water.
