Can SMP Be a Permanent Concealer?

Here’s two similar questions from two different readers:

I know scalp pigmentation is great for people with short cropped hair but my hair is about 1.5″-2″ long. Can scalp pigmentation of the crown play the same role as concealers like Toppik and DermMatch in people with my kind of hair?

Would SMP procedure on the thin areas of a scalp, covered up by some of the balding hair, serve as a sort of permanent hairloss concealer or at least aid in the cover up of hair loss? Has anyone tried this, any pictures ?
Thanks for your time!

Scalp MicroPigmentatation (SMP) is a great way to decrease the contrast between your scalp color and hair color, giving an illusion of fullness. So yes, you can think of SMP as a “permanent” cosmetic concealer… but with SMP, you won’t have to worry if your scalp is showing from an uneven application. Another added bonus is that unlike with some cosmetic concealers (like Toppik or DermMatch), SMP doesn’t run the risk of leaving a stain on your clothing, pillow, or on your significant other’s fingertips.
