I'm not a fan of eyelash extensions. They look beautiful! But they are an expensive up-keep and aren't the best for your natural lashes!
Before you think that is your only option, consider using Revitalash first!
You can find this at NEW IMAGE DAY SPA. (starting at $90)
You apply to the base of your lashes, top and bottom. Usually before bed when you have no make up on. You don't have to wash it off. Apply every night. Note that this does not thicken your lashes, but it helps the lashes you DO have to grow. Then all you do is buy a mascara that thickens, and you should have long.lush.lashes! It should take about 4-5 weeks for you to notice results. And if you don't, you can return for a FULL refund!
I have used it myself and have noticed such a difference! I recommend to everyone. It's cheaper than extensions so it's worth giving it a try!
