The patient’s eyelashes can grow back when they are cut short, just as they can grow back when they are plucked, as long as the hair follicles are not destroyed. There is a kind of inverted eyelashes surgery, is to use a needle to stimulate the conjunctival sac, and then electrolysis, after electrifying the hair follicle destruction, so that it will not grow. Eyelash cutting and plucking will not damage the conjunctival follicle and will grow back. Eyelashes are in a constant state of metabolism and renewal, and will usually grow back in about 3-5 months. Eyelashes that have been removed or plucked usually grow back in a week or so, and when they do, they grow about 1-2mm a week, and then they grow back to their original length in about ten weeks. So people who have their eyelashes plucked usually need to go to the hospital once every 1-2 months to have them plucked again, and after they have grown to their original length, they will continue to grow for five months, and then after five months they will fall off again, and after they fall off they will be metabolized and renewed again, and they will be in a kind of cyclic state.
