Tricopigmentation is commonly referred to as temporary scalp micropigmentation, which is a pretty accurate descriptive. Whereas a permanent procedure will need top-ups every 3-5 years or so with pigment remaining in the skin for 20+ years, tricopigmentation is refreshed almost entirely every 12-18 months.
People sometimes consider tricopigmentation a safer option, or an opportunity to test drive their new look and maintenance regimen before committing long term using permanent SMP. However, most people who choose tricopigmentation do so with the intention of getting it regularly topped up, and have no plans to revert to the permanent option. It is a great choice those who wish to alter their hair line in the future to suit their age.
The availability of a temporary procedure definitely encourages more people to resolve their hair loss issues because tricopigmentation is less daunting for those who are yet to be convinced that SMP is the right solution for their needs. If, after their procedure, they feel like they made a mistake, the pigments will fade on their own over a relatively short period anyway. This removes much of the anxiety from the decision.
