Male Baldness Info

I started using Head & Shoulders shampoo last year. After a few months on H&S I noticed a small bald spot I had on the top of my head towards the back seemed a little larger, but dismissed it for just being the way the hair was pushed. However, lately when I switched to a new Head & Shoulders formula, my hair started rapidly thinning to the point where theres a line of almost baldness with the hair going in either direction the way it grows on the crown of my head.
After some research online, it seems like others are reporting this issue as well including teenagers and its all occurring on the same part of the head.
I’m 21 with thick hair and absolutely no Male Pattern Baldness in the family. The fact that this is happening so rapidly has left me wondering whether or not it actually is MPB or if it’s a reaction to the shampoo that only a small number of people get.
Information on this issue would be greatly appreciated. Thank you.

We just adopted two kittens last week; they are 8 weeks old. They’ve been dewormed, had their first round of shots (second to follow in the first week of July), were treated for an upper respiratory infection, supplemented with Lysine paste, and are otherwise very healthy, active furballs.
Last night, I noticed a dry, crusty, flaky patch (bald) on the orange male’s front elbow area; kind of on the outside of what would be his “armpit”. It looks like a rough callous almost. He shows no other signs of irritation/baldness/dry skin elsewhere.
We’re planning to take them both to the vet soon, but are wondering if anyone else has had similar experiences. I know ringworm is usually found on the face/head/ear area, and doesn’t usually get flaky/crusty until it’s advanced. Mange is another possibility, but again – it’s very isolated.
Is it safe for us to try a human anti-fungal cream (Monistat, Lamisil) to see how the flaky patch responds?
FYI – they are indoor cats.
Thanks!
