To give false eyelashes maximum staying power, put extra glue on both ends of the eyelash strip because these areas are more likely to come loose. I would also recommend using a great adhesive like the Revlon Precision Lash Adhesive (£3.56 Tesco / $3.93 Walmart) or the Eylure Lashfix Adhesive (£2.75 Boots / $5.69 asos.com).
