Biotin and itchy scalp and growth

Hey, i've just started taking biotin

1000mcg supplements 4 times a day

2 50mcg zinc supplements and your

normal vitamins and minerals

i've found that my scalp is really

itchy these days. Does this happen to

anyone else who taking biotin? Also i

wanna know how much growth

everyone has had so far this year.

Mine is a measly 2 and 1/2 inchs :(
