Using Phytodefrisant

Hi all, decided to try using Phytodefrisant after reading reviews on it - but there's something I'm not quite sure of.  I have fairly short hair, which can only be described as wavy/loosely curly.  I usually spiked the fringe with wax but I ended up looking like Tintin with a less-than-great looking rolly quiff and the rest of my hair flat!

I've recently begun straightening the fringe and spiking it up with Daxwax which looks much better because it looks longer and my hair looks layered and textured, but using the straightening irons is a pain in the ass, I don't think I could do that every day, and I'd be quite embarrassed to admit I use them to be honest.

So anyway enough background - the question about Phytodefrisant - do I have to blowdry my hair after applying the balm or is it good enough to apply the stuff and combine it with Daxwax to get a straight look?
