A laxometer is a measuring device for scalp skin mobility used in hair restoration surgery where a strip of skin from a donor area on the back of the scalp is transplanted. A laxometer determines the laxity or looseness of the scalp. This information reduces the risk of donor complications when a surgeon cannot easily close the donor wound after removing the strip of skin from the donor area. This is relevant for those patients who have a high demand for hair and scarce resources.
