If I had scalp micro pigmentation a week ago is it ok to drink alcohol with out risking the pigment fading away?

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.
Consuming alcohol a week after the procedure should not have an effect on the healing process.

It is best to follow up with your doctor for post surgery questions and concerns. Drinking alcohol should not affect the SMP results.

Go for it.  Won't be a problem this far out.  You may want to refrain from alcohol 2-3 days before your next treatment.
