Hi Cara,
Wether you are having a full set of fake eyelashes or individual eyelashes they still look fake, my best advice to you would be to buy a cheap set and research the best volumising mascara available on the market and try both of them out. Try asking friends and family for their opinion or why not try them on for a night out. As for horror stories problems occuring through
wearing fake eyelashes are rare but things like eyelashes falling out are possible, but by wearing fake eyelashes for only a few hours it shouldn't cause much harm, I hope this was useful.
