Normally, not all of your eyelashes fall out at the same time. They replenish gradually day by day. You might loose 1 or 2 lashes each day but when your lashes are short, you don't notice it because they are all pretty much the same length. But when your eyelashes are extended, when some lashes fall off, you notice them right away because now, there is a length and thickness difference. Not to worry. When some lashes fall off, there are plenty of new ones that have come out ready for the eyelash stylist to refill. Call me to be beautified again. Some people like the full look all the time and come in every 2 weeks, some prefer coming every 3 weeks. You can come as often as you want depends on your financial and time permit.
