I’m blonde and eat a lot of pineapple. You’ve got nothing to lose. If you’re not used to the taste, it’s a pretty popular pizza topping and you could try it that way.
I still remember a rumor that there was a kind of trend in the late 90s or so where pregnant women dyed their hair blonde thinking that will made their children have natural blond hair
IIRC hair dying is not great during pregnancy. It is slightly, but measurably oncogenic in children of mothers who died hair during pregnancy and breastfeeding. https://pmc.ncbi.nlm.nih.gov/articles/PMC3543291/
