Which video? The Meza one?
I use only maybe a quarter sized puddle. Or a half dollar sized puddle. But this is followed up by gel or gelly. When I tried it as a styler alone I had to use a lot more. For volume at the roots I cross clip while drying but I know you don't like the metal clippies. (Lovely Jules got bigger ones especially by deva though and says those don't snag or fall over.) Are the root lifting clips you were using not working out for you any longer? Another thing you do is bobby pin some sections strategically for added root volume. That works really well with coarse hair and it's easy.
