Is There a Pill to Prevent Shock Loss?

What is fallout/Shockloss? Is there a pill or something I can take after surgery to prevent it, or is it temporary and nothing to worry about?

I just made a post related to this yesterday (see How Long Should I Take Propecia Before Transplant to Prevent Shock Loss?).

Shock loss occurs when the follicle becomes ‘insulted’ by swelling and inflammation, causing the hair to shed from the follicle. The follicle then enters a resting state and may never go back to an active state (if there is genetic balding in that particular follicle) or after a period of time it may go back to an active state and grow normally again. We suggest taking Propecia before the surgery to help minimize shock loss after hair transplantation because the hairs that are genetically impacted have the greatest risk of permanent loss from the shock of the hair transplant process. Propecia minimizes this risk.
