Got my 2nd bottle of OS Spray yesterday after the 1st bottle ran out 1.5 weeks ago or so. During this period, I used the Wella Ocean Spritz to "dong" a bit longer while waiting for the 2nd bottle to come.
I've got some PMs regarding the Wella ocean spritz ever since I posted a question on that previously. For anyone interested in how the OS spray stack against the Wella one, there is no contest. Even after pouring the Wella spray onto my hands, the result is weaker than applying half that amount of OS Spray.
The Wella spritz is $10+ more than the OS spray, and the hold is a lot weaker and softer and you might as well not apply. OS spritz when applied in proper amount can last pretty much more than 24 hours under normal conditions (ie: no drenching by rain or under wet-wind condition, hair not soaked by extreme sweat).
