A scalp micropigmentation treatment, correctly applied to the right depth and using a suitable pigment, can be almost completely removed in just one laser session. A second session is usually required to complete the process entirely, especially if the area is large. It’s quick and easy, albeit a little uncomfortable.
However, pigments deposited deeper in the skin, and the wrong type of pigments, are far harder to remove. They generally require the same process as a tattoo removal which takes more sessions, is more uncomfortable and is less likely to be 100% effective.
Laser removal should not be taken lightly. People get burned and scarred by these machines through improper handling. Thankfully most laser clinics are competent and offer a highly professional service, but still, laser removal should only be resorted to if you’re absolutely sure it’s what you want to do.
Also please note that darker skinned clients are at greater risk of either hypopigmentation (skin lightening) or hyperpigmentation (skin darkening).
