what is microblading? am I a good candidate? 

Microblading is  the semi-permanent answer to thin, sparse brows. Microblading, also known as eyebrow feathering, 3D brows or brow embroidery, is a personalized service done by hand guaranteeing a natural hair like result. Unlike permanent tattoo methods, Microblading fades naturally in 9-18 months allowing touchups for as long as you like with the option of changing color, shape or thickness as time passes.
