Considering scalp micropigmentation in or a tattoo? There’s more than aesthetics to think about.


Despite what some scalp micropigmentation and tattoo artists will tell you, ink does enter the bloodstream. This has nothing to do with the artist’s skill or how “experienced” they are. The materials/inks used are critical to your safety, and tattoos are not regulated, so be aware of the risks.

Tattoo pigments are small particles. In most situations, the macrophages carry those particles to the lymph nodes close to the site of the tattoo. Because the cells can’t break the particles down, they get lodged the nodes. This causes the node take on the same color as the tattoo.

An EPA Danish study showed 1 in 5 tattoo inks contained carginonic chemicals. Another Danish study with black and red tattoo pigment suggests the pigment particles are deposited in the skin, lymph nodes AND the Kupffer cells of the liver.*

If there are auto-immune issues, I never recommend tattooing.

In a healthy person, I urge caution with scalp micropigmenation. Not only are there safety concerns, but pigments change color – they are easily oxidized and “color bleeding” occurs.

This isn’t to say you should not get a tattoo, or scalp micropgimentation, but use caution when considering the practitioner. How long have they been practicing, look for before and after photos, and ask for references. And, finally, take your time. Do the research and wait 24-48 hours before you make a decision.
