The DigniCap Scalp Cooling System is operated by hospital personnel and will be used during each chemotherapy session. Scalp cooling begins approximately 30 minutes before chemotherapy starts, continues during the infusion and must continue for a set period after the conclusion of treatment depending on the chemotherapy drug and dose, typically 90–180 minutes post infusion. After completion of the post-infusion cooling time,the cooling cap remains on your scalp for another 5-10 minutes while you re-acclimate to room temperature.
