Orange hairs mean pollenated?

I had a large female hermie on me and I took it out, but some pollen may have spread by the time I got to it.

A few of my plants tops have started having brown hairs..

This is my first grow. So are brown hairs normal or not?

Goes both ways. If the hair served it purpose and had pollen on it, well it is no longer needed and dies. If the hair has reached it's end of life it dies.
