Cutting your hair every 6 to 8 weeks does not let your hair grow any longer at all That is a crazy idea?

Cutting your hair every 6 to 8 weeks does not make any sense. Imagine, hair only grows 1/2 inch / month and then you cut it when it does not yet reach the half inch. So how would you see the growth of hair. That is madness. But it is possible that Mane and Tail can help. But the others like yogurt, eggs,mayo,pony tailing, that is insane.
