how long does it take to grow out eyelashes?
At the end of the resting phase, the hair will fall out, meaning that new hair will soon come out. To give you an average estimate of how fast eyelashes grow back, itâs anywhere from 1 to 6 months. Mine, luckily, grew back in just 6 weeks. You need to take very good care of your eyelashes if you want them not to fall. That is why you should: 1  Throw out the makeup (eye makeup especially) every 4 to 6 months.  Try and be gentle with your eyelashes and donât rub them too hard.
