Unsure

Okay so I’ve noticed recently that my bf has head lice , I know that it’s something that just happens & most of the time it cannot be prevented , I’m not disgusted or turned off by it , it’s no biggie

But the thing is obviously I don’t want to get head lice aswell but I don’t know how to say to him hey you have headlice are you going to do something about it , without him being embarrassed or uncomfortable as he doesn’t know I know & he hasn’t said to me “hey I have them” & he hasn’t made the effort to get rid of them , but I don’t want him to feel embarrassed or anything so how could I bring it up , we are very very open with one another but some things can be a lil awkward to bring up such as this situation

Or should I just be straight forward & get it over & done with
