The principle of eyelash implantation is that the doctor first takes out the healthy hair follicle tissue in the pillow through microsurgery, then separates the hair follicle tissue specially, and finally transplants the hair follicle to the cilia. After the hair follicle survives, it can naturally grow new eyelashes and keep all the characteristics of the original hair.
Extended data
When you are in grafting eyelash, your eyes must be closed to prevent glue from entering your eyes. Moreover, in order to make the glue more sticky, you must lie flat when you start grafting eyelash. If you grow your own eyelashes, you must look at the mirror and graft them. Grafting eyelash can't control the grafting eyelash at one third of the user's real eyelashes.
And from grafting eyelash, glue may drip into the eyes, causing harm to the eyes. So if you want grafting eyelash, you still have to go to a professional eyelash shop for grafting. Even a professional eyelash teacher can't do professional grafting for users.
