Scalp Micropigmentation (SMP) is also known as trichopigmentation. SMP is a highly sophisticated technique of a cosmetic pigmentation. In scalp micropigmentation, a series of tiny dots are created with the natural or non-toxic ink onto the bald area of the scalp or even in between the hair. Due to the pigmenting of the scalp, you can have the appearance of the fuller, thicker and look of the closely shaved head. If these pigments fade away or you want a darker shade, you can also go for a touch-up process.
