Scalp micropigmentation (SMP) is a cosmetic treatment that creates the appearance of hair in people with baldness or thinning hair. It is sometimes called a "hair tattoo" or "hairline tattoo". During SMP, a skilled technician uses a fine needle to deposit tiny dots of color on the scalp, creating the appearance of thicker hair. The dots vary in size and depth, and the chosen ink color matches the current color of the hair follicle. SMP can cover thinning areas on the scalp, birthmarks, or scars. It can also be used to create the look of a buzz cut on someone who is bald. SMP is a non-invasive procedure that doesnt require surgery or anesthesia. It is a permanent treatment, but it can be removed with laser treatment. The cost of SMP depends on a variety of factors, such as location, proximity of the clinic, and the severity of hair loss. The procedure takes three to four sessions, which usually last about two hours each. SMP is suitable for people looking to alter the appearance of alopecia, male or female pattern hair loss, or hair loss from cancer treatments. It can also cover scalp scars, such as those from a hair transplant surgery.
