I agree Cabby. I did the second course as I actually love it myself but didn't get on with Xaggerate. I wear it constantly in fact, don't even own a mascara these days!
I think I've only done 1 top and bottom treatment since the second course!
I do, however, use it a lot for lash extension clients on their bottom lashes, almost all my regulars have it on their bottom lashes, I charge 10 euro for it, its a little add on.
Worthwile for that but not as a standalone treatment I would say.
