How can I grow my hair in 10 days

How can I grow my hair in 10 days as my hair was very short

Hair will continue to grow, and in 10 days, you can expect it to lengthen about 4 millimeters (5/32"). Although there are many claims to the contrary, there is nothing that will make your hair grow any faster -- unless you have some sort of illiness or deficiency. Then, correcting that will help.

You can't make hair grow long in 10 days. Maybe you can try hair extensions if you want your hair to look longer.
