This hairline mapping tool is designed for scalp micropigmentation and comes in three sizes—half an inch, three-quarter inch, and one inch—corresponding to different hairlines based on the client’s age. The stencil allows you to mark lines without freehand drawing. You simply place it, mark the designated guide lines, remove the stencil, and you have a natural outline ready. Whether you’re creating sharp SMP hairlines, applying hair fibers, or fitting hair units, it ensures a crisp finish. It’s not only for SMP artists and barbers—cosmetologists can use it for men’s hairlines in various styling scenarios. Versatile, precise, and easy to use, it’s your go-to for consistent, professional results.
