I had my hair transplant 3 weeks ago and I started walking outdoors for about an hour instead of going to the gym to walk on the treadmill. I know that it is not advisable to stay under the direct sunlight for a long time however I am quite fussy so I would not do that at all however I would like to ask you if this is still OK to walk in a cloudy day when the sun is hiding itself behind the clouds, which means no direct sun lights at all, Does this still affect any graft at all?
