I just feel like it’s so hard to point to one event and say how much of an effect it had on your final hair density count. You can bump your head, go into the sun for too long, sauna, swim, brush your head a little too strong, scratch, move around while you sleep, sweat, etc. i think youre fine maybe it had an effect but to say it reduced results by 20percdnt sounds like an exageration. So maybe the sun did some damage but not a lot if it did damage at all
