How soon after transplant can I use silicone gel for scarring?

My patients are not encouraged to use scar creams, but I have no problem if it is utilized once the incision is healed in 3 or 4 weeks. I would encourage applying horizontally if placing on an FUT (linear scar) to avoid potential stretch back if applying vertically. If FUE scars, it should not make a difference how the scar cream is applied.
