K, first...a few of those replies that came before were spam. Just to put that out there...
Okay back to my reply:
You said you started seeing major hair loss over a few days?
K, noboody goes bald in a few days..or even a few weeks.
It takes months for the hair to start to heavily fall out.
Balding is very much a slow eventual process... unless you're on chemotherapy. But I'll assume you aren't, since you didn't mention anything regarding cancer or chemotherapy.
K, so...
you said you saw "pieces" of hair falling out.
what in the flaming hell is a piece of hair? Single hairs with bulbs attached?
Several hairs?
If it's single hairs, you're getting yourself sick with worry over nothing.
Everybody loses hair! The average person (this is ANY human being with hair on their head), loses about 50-150 hairs a day.
Unless you're able to pull out large thick chunks of hair out of your head with minimal effort or discomfort, you're not going bald.
And as for the thin on the top and front, I have the same thing as you.
Sometimes people just have thinner hair on the top and front of their heads.
It varies for each person. It's a very bad idea to wear a hat a lot. that could be part of the problem. Another thing is the umm...what else..hmm
Well, that's it, basically.
