Hi,
Just that really.
I have thick ish, coarse, wavy to curly, highlighted, so quite dry, hair.
It actually blow dries quite well and with the magic of the Dyson Airwrap, can get it looking all swishy and smooth. However.... if there's ANY sign of humidity in the air, I look like I've been dragged through a hedge backwards
or - as said - Monica in Barbados 
I'm going away to Spain (hopefully ) next year and I'm dreading that daily battle with the mane. I tried standard hair spray last time I had a beach holiday and that had little effect.
Any recommendations? I've seen quite a few products claiming to do this, but with varying reviews.
TIA
