Ohhhhh yes...I love Helmet Head!!! It leaves terrible sticky residue on my bathroom walls that's impossible to get off, but it's the best finishing/holding product I've ever found for my fine hair. If you watch for it, sometimes it pops up at Winners/Homesense (I see you're from Canada too)...and when the travel-sizes show up, I totally stock up for my vacations!
I have the best hairspray to recommend for you! CHI Helmet Head Hair Spray.
My wedding was in Aruba, where there's always a trade wind. The wind has an effect so many aspects of the wedding - basically everything not nailed down! My mom asked every single bride that got married at our resort before me how her hair stayed so well. Every one of them said that her hairdresser used CHI Helmet Head Hair Spray, as did mine. It appears to be every Arabian hairdressers secret weapon!
