First of all, to avoid any confusion, here are all the different terms for Scalp Micropigmentation: SMP, micro hair tattoo, cosmetic tattoo, hairline tattoo, micro hair pigmentation. They all mean the exact same thing.
SMP is a semi-permanent cosmetic tattoo that lasts for many years. Thousands of micro-dots cover up balding areas such as the crown or hairline to create the illusion of trimmed hair stubble.
The “magic” is achieved in stages—you normally need 3 sessions to blend seamlessly with your remaining hair and achieve a perfectly realistic, natural look.
