It's not that strange for women to be capable of something like that, I've had chemicals tossed over me by one aswell, just because I refused her advances.
And while I still don't know what kind that was, it did result in some skin burns, hair turning more elastic than rubber aswell as losing all color (not even white), most of it stopped growing and fell off within a couple of years.. (Unaffected areas retain my naturally dark haircolor, although the stress from everything did result in streaks of white already back in my twenties.)
On the bright side, didn't get anything in or near my eyes/nose, and not spending time on combing/brushing hair since it's utterly pointless when it just stretches then retracts back into a huge mess as soon as it passed through the comb/brush, and after a bit of time showers go faster with the lowered amount of hair to wash through.. And the burnmarks more or less disappeared after about 15y. =D
(I'm also unattractive enough now that I haven't really had troubles from women I refused since then, hardly had any to refuse either since which makes my life alot easier.) ^^
Btw, for those that claim it's difficult to understand or predict women..
Just stop assuming they have any empathy, and it'll be ALOT easier to predict their actions.
(Empathy is in rather short supply among women when compared to men, which is also why women are better liars compared to men, easier to lie when you feel no guilt about it.)
Last bit, women are generally considerably more perverted than men, both thinking of such more frequently aswell as their imagination running off into more wild and extreme versions when they do.
Men just try to be perverted and usually fall short compared to women. =p
