How long after a hair transplant can I wear a hard hat?

Hi there, I have a question regarding hard hats. I’m due to get A hair transplant done on the 1st October and then I need to return to work 2 weeks later. With my work I need to wear a hard hat at times, but I only have to wear the hat for no more than 45 minutes every few days or so, it’s not continuously the full day. After 2 weeks of getting the treatment would this be ok? Is there anything I can do just to be extra cautious like wearing some sort of soft cap before wearing my hard hat? Thank
