What’s best to apply to 20 day old donor and recipient areas? (photo)

It is best to contact your surgeon for post surgery issues and care since all doctors have slightly different instructions.

 Using Bepanthol is a good choice and certainly Aloe Vera wont hurt either however neither should replace proper washing during the initial post op period.  The redness you are experiencing after a hair transplant is commonly seen in lighter skinned individuals.  This should resolve in the next month or so.  Do wear a hat or sun block otherwise the redness will be replaced by purplish/brown hue as this is post surgical healing scalp and sensitive to the sun.

At 3 weeks you can use almost anything you want once the scabs are off of your recipient and donor area. The pink color I see will go away with time
