Sorry, that cannot be done . Hair grows about 1/2 an inch per month .
How to grow your hair 1 inch in 1 week?
Not 1 inch in ! Week definetely you need patience for your hair to grow too .. Eats vitamin food and also apply hair oil everyday to make it grow faster .....
It's not possible sorry. But every month the average hair grows about half an inch. Trim your hair every now and then, and it will grow even faster!
