How long after an eyebrow transplant can I resume cold water scuba diving?

How long after a eyebrow transplant can I resume cold water scuba diving? My worry comes from donning and doffing a drysuit with a latex neck seal and hood as these actions often pull at the skin and hair (there's now way around it). Also, should I be worried about consistent icy water on the face and pressure from the mask on the brow area? I'd like to be conservative to gain the best results possible.
