Sun exposure: the sun will extremely soften the look of your tattoo, so sunblock should be used (once healed) to prolong your enhancement.
The regeneration of skin cells: the longer the regeneration takes, the longer the pigment holds.
The speed at which the skin absorbs the pigment: the slower the absorption, the longer the pigment will hold.
The choice of color: some colors fade quicker than others, e.g. A blonde color will fade quicker than a dark brown color. The area of treatment: enhancements to the face, for example, fade more quickly due to constant exposure.
Bleeding during the procedure: any bleeding during the tattooing procedure will reduce the amount of pigment absorption. Alcohol and certain medications act as blood-thinners and should not be taken prior to and following your appointment.
Aftercare: failure to follow the aftercare diligently during the first 2 weeks of healing can contribute to less than desired results. For example sweating during healing can effect the appearance of the hair strokes when fully healed.
Iron deficiency: if you suffer from anemia or low iron this could affect the way your body reacts to the pigment. The pigment used contains iron oxide which can result in the hair strokes to fade or change in hue due to your body absorbing the iron.
