I recently had SMP. Does SMP compromise the health of scalp enough to jeopardize the hair already transplanted there?

Scalp MicroPigmentation or SMP is basically a tattoo.  When done property, it should not harm the surrounding hairs or skin.

SMP, or scalp micropigmentation, is a painless procedure that uses highly specialized equipment and unique techniques to carefully and expertly inject all-natural, color-tailored pigments into the scalp creating a completely natural look of the patient’s hairline. A typical procedure involves an initial consultation and two pigmentation sessions to achieve the desired results. You can wash your head the fourth day after the treatment and, during that time, avoid any strenuous activity that will prompt undesired sweating. Once the procedure is complete, the results of a Scalp Micropigmentation treatment can last up to five years.
At the Foundation for Hair Restoration in NYC, I work with the world-renowned hair expert Dr.Jeffrey Epstein and his team to create beautiful, natural results for any hair type.
SMP is delivered more superficially and therefore will not effect the rest of your hair.
Consult with an experienced hair restoration surgeon for a complete range of options that are appropriate for your situation.

SMP does not compromise the health of the scalp if the procedure is done in a hair transplant surgeon's office that provides this technique in safe and clean approach without jeopardizing the transplanted hair.
