I use the folligen spray on my scalp 2-3 times a week with great results. I know it's good for the hair follicles, but is it also good for the hair itself? Obviously, I get it on my hair when I spray it on my scalp, I was just wondering if it has benefits for the existin hair as well?

Some people do use it for their hair but it main effect is to supply nutritional copper to the hair follicles in the scalp so they can function optimally.
