I want to SPEED UP MY HAIR GROWTH WITH BIOTIN? but how much can i take?

im a male, i wana speed my hair growth with biotin i bought, i've read about people taking 5micrograms of biotin daily..is that enough? and i want to take vitamin c 1000mg capsules i was wondering if i take 1 1,000mg of vitamin c tablet and like 3,000mg of biotin is that safe because my biotin is in 600 mg tablets so is it safe?
