The roots of the new eyelashes, which are taken from the donor area and placed on the eyelids, attach to the area where they are planted within 4-6 weeks. This process takes place over a period of time that varies from person to person. After the shock shedding, the eyelashes begin to grow and look natural.
Since the roots of the transplanted eyelashes are taken from the scalp or from a different donor area, they may grow more than the normal eyelash size. Extended eyelashes should be cut for a period of time and brought to ideal eyelash sizes. Over time, the roots that get used to their new place will not grow too much.
