Sunburn at 6 month after hair transplant

I am 6 months and 10 days after my second hair transplant and I am very satisfied with the result, I am starting to behave as if I had not done a transplant seeing myself very well, so I am no longer taking the typical precautions, for example today I have taken sun and unfortunately I have not put sunscreen on the head nor cap. The sun was strong enough today and I took it for about 2 hours, I am now seeing that a red blotch has formed on the upper part of the forehead just before the hairline, but NOT on the skin, that is right where the hair starts. skin, in that point, looks white perhaps because there are so many hairs now that have protected the head from the sun. This red stain on the upper part of the forehead clearly scares me a lot now though, even if it doesn’t burn. I am reddened in that point but I don’t feel burning. The questions I wanted to ask are: at 6 months, a possible sunburn of this type can make my hair fall out: the hair regrown until now with the second transplant? Or could it compromise the growth of future hair?
I would like to understand if at 6 months I can behave as if I had not done a transplant or if there are still precautions to take, thank you very much. I hope in your answer

Don’t worry. Just be more careful in the future to use a hat or a skin blocker. The skin from the transplanted hair came from the back of the head which never saw sun, so this skin has to get used to sun over time, so take it easy and use a blocker to allow the time for a transition.
