Wow they lasted 4 days? That's great!! Usually I cant get mine to stay on more than one day.... If you just Google eyelash extensions in your town, places near you should pop up....I guess it depends on where you live. For instance, I live in Boston and you can get them at hair salons, medi spas, dermatology offices, and there are even boutiques that specifically apply eyelashes. I believe prices probably depend on where you live as well. Ive seen anywhere from $200-$300 here in the city, but there about $150 in the small town where my parents live. Not sure if you're familiar with Groupon, but sometimes they offer deals on local salons that offer extensions as well.
