I am sorry to disappoint you but 'absolutely nothing' is going to make your hair grow faster! Having been a hairstylist for 35 years I can tell you with absolute certainty and anyone telling you otherwise is feeding you old wives tales.
It's scientifically impossible because hair growth is genetically predisposed. The average hair growth per month for human beings is 1/2 inch. Expecting something to make your hair grow faster would be the same as expecting to miraculously grow taller after you've reached your personal genetic height.
Have your hair thinned but not shortened and it will be longer as it will lay flatter. If it is curly straighten it. Other than this I would think you won't make it.
Are you serious? There is nothing that can grow your hair with an discernible difference in 3 days!
First, zinc and iron are good vitamins to take to grow out long hair. Also, using olive oil shampoos (you can find them online if you look) provide shine and hair growth. Also, go to a massage salon, and if they offer scalp massages, those supposedly help induce hair growth, although I am not sure about that.
