The pigment is applied with a specific Phi brows tool that has a row of several fine needles to create thin hair-like marks in the skin.  Your artist will choose needles and the blade type according to the technique and skin type.  The pigment is bladed just below the epidermis and the most shallow part of the dermis, making extremely fine natural looking hair strokes.  A very natural result is achieved, as the hairs are bladed into the skin according to the natural hair growth direction.  The first initial service takes about 2 hours depending on the client and their brow condition, shape, and desired results.  Touching up will be necessary every 4-6 weeks after your initial treatment.
