We will give you care instructions before you leave our office and make sure you understand how to optimize your results. Some common ways to care for your newly tinted eyelashes, however, include: Keep your lashes dry for two days after tinting Avoid oils and oil-based cleansers that may strip out the dye (use gentle gel cleansers instead) Utilize eyelash serum that will hydrate your lashes and help them from falling out Try to sleep on your back, as putting pressure on your lashes by pressing them against the pillow may cause them to fall out faster Don't rub your eyes
