Dignicap Scalp Cooling Starter Kit. Normally $250 online plus shipping online, this starter kit is required to use the dignicap scalp cooling system. It allowed me to preserve my hair during chemo successfully. The way it works is by cooking the scalp, the blood flow is less to the scalp so the chemo doesn’t effect the hair as much. As a cancer survivor myself, I used this system during chemo and managed to preserve the majority of my hair and look normal so as no one noticed.
