What is Scalp Micropigmentation (SMP)?
Scalp micropigmentation (SMP), also known as a hair tattoo, is a cosmetic procedure that uses a medical tattoo machine to create tiny dots of pigment on the scalp to create the appearance of thicker hair. The dots can vary in size and depth, and can give the appearance of a buzz cut or stubble on a bald head, or make thinning hair look denser. SMP can be used to treat many types of hair loss, including: Alopecia areata, Chemotherapy-related hair loss, Hormonal conditions that cause hair loss, such as polycystic ovary syndrome (PCOS) and male and female pattern baldness .
