Comparing the two products, I would say that Surf Spray gives more volume, gives softer waves and holds your waves in for a longer period. However, if I use this too often and too much, my hair gets quite dry and can feel gritty. A Perfect Mess smells like summer in a bottle, is lighter and much less damaging and gives your waves a more defined look. I find that if I spray on too much, my hair can get crunchy (which I resolve by running my fingers over the strands).
Verdict: I LOVE both products, almost equally. But if I had to weigh in the damaging factor and the price, it would definitely be Charlotte Ronson ($24 CDN) over Bumble and Bumble ($30 CDN). I would recommend A Perfect Mess if you'd like to create beach waves every day and I would recommend Surf Spray for days that are long and you'd want to make sure your waves last.
