We only use the latest in SMP technology. The Scalpa Machine is not a permanent makeup pen or a paramedical tattoo device. The Scalpa Machine is designed to deliver high quality scalp micropigmentation procedures as its primary function. The Scalpa Machine has a stroke length of 5mm. This longer stroke enables the technician to deposit more ink into the scalp while still only penetrating the outer layer of skin. This technique results in less fading, a fresher look and creating a follicle replication to appear realistic.
