A detection method of detecting hair for planting planted on a mesh of a mesh-like base material, includes: an image acquisition step of acquiring a pre-image of the mesh targeted for hair planting of the base material captured before hair planting and a post-image thereof captured after hair planting; a transformation matrix acquisition step of acquiring a posture transformation matrix of the mesh from the pre-image and the post-image; a difference step of acquiring a difference image between a transformed pre-image and the post-image, the transformed pre-image being obtained by transforming the pre-image with the posture transformation matrix; and a hair detection step of specifying the presence or absence or a hair planting position of hair for planting with respect to the mesh from the difference image.

Process for a customized production of skin patches, for realizing a customized patch according to a shape of the scalp of a patient for hair thickening purposes, comprising the following main steps: (a) patient mapping to collect all the information and map the patient to create a digital copy of the same (digital twin) by 3D scanning and production of the template structure by 3D printing; (b) setting of the template for machining consisting in the application preferably of the compact elastic polyurethane; (c) application of the hair by approaching the same to the template connected to the suction system: o suction of the hair inside special holes; o heating the polymeric film close to the melting point, incorporating the hair therein so as to obtain the desired natural hair effect; o cooling.
