Lash extensions typically last anywhere from three to six weeks, depending on how well you care for them. If you're diligent about using lash products that promote healthy growth and taking care of your lashes in general, they can last much longer than 3-6 weeks;
If you're not careful with your lashes (if you don't get regular fills or touch them too much), your extensions will only last a few weeks before they start falling out or breaking off at the root. As long as the lash stylist did her job correctly and chose lashes that are right for your natural lashes: by choosing the correct thickness and length suitable for your natural lashes, the lash extensions should stay for up to 5-6 weeks.
It is still important to take good care of them after getting them done so that they'll keep growing strong. Follow the correct lash extension aftercare by washing the lashes daily and brushing them regularly.
Key words: lash extension after care, eyelash extensions maintenance.
