You should not wash your hair for 3 days after the implementation. During these 3 days some little crusts will appear and your scalp will look darker than usual. After 3 days, when you wash your hair, the look will be natural. We explain our patients what to expect after the simulation. There is no healing period or any other stages of post implementation in hair simulations. There is no need for a special treatment, special care, or any special guidelines.
