Eyelash extensions can be worn 24/7. You don't have to worry about them coming unglued in the middle of your good times. Extensions can be worn while you do your day to day activities. You can swim, surf, do hot yoga or cool yoga. :) I have had 2 clients visit Thailand and the weather temperature there was 130 degrees with about the same percentage of humidity. Granted, this is an extreme test but they really held up well. They were thrilled that they looked so good even with sweat dripping down their nose.
The part that is so great about eyelash extensions is every day there is minimal upkeep. In fact, I tell my clients that the less you touch them, the better they stay.
For all you future brides... consider eyelash extensions over the "strip lash". I have seen some bad photos of brides that you can clearly tell they have false eyelashes. One of my favorite benefits of eyelash extensions is that you cannot tell you are wearing them. They are that lightweight.
