Scalp Micropigmentation, or SMP, is a cosmetic procedure that uses micropigmentation—a permanent makeup tattoo technique on the scalp. Danielle uses a pen-like tattoo machine to implant tiny dots that mimic hair follicles. If you’re bald, the results will look like you’ve just shaved your head, and if you still have hair but want to fill in some areas, it camouflages the empty spots and makes the surrounding hair look thicker. It can also help hide scars and can be used on all skin tones, though if your scalp is prone to inflammatory skin conditions like psoriasis or eczema, you’ll have to clear that up before you can get SMP.
