I also have lots of trouble with my hair when there is alot of humidity so I took my hair appliances to Negril. But even though the plug-ins worked - my curling brush started smoking immediately when plugged in for the first time and became toast and my flat iron actually fried my bangs! I was using it at the same temperature setting I always use at home too but it must have become overheated. Freaked me out because I was there as a bridesmaid for a wedding and I had to do damage control on my hair to try and hide the fried hair. We were staying at Rooms on the Beach. I did not even try my hair dryer that I had brought. I just used the one provided. Just be fore-warned that this could potentially happen.
