Yes! A touch up session after 4-6 weeks is necessary as everyone heals differently and outcome will vary. Certain areas may not pick up during first session and will need to be refilled. Pigment color may need to be adjusted, brow thickness and more strokes can be added. Individuals with oily skin often require a deeper shade during the touch up session as the oils tend to lighten the pigment. Most importantly, your touch up session is when we refine your brows to ensure it looks perfect and retains the color for the whole year!
