my hair length goal is waist length. i am current 6 inches past the shoulders. how much longer till i get to mid back and then waist length? within 6-10 months before waist length?
Hair grows on averrage about 1/2 inch a month. You do the math.
For healthy people hair normally grows at up to 1/2" per month. So given that you do not give any dimensions about the size of your back you will have to undertake the calculation. That should not prove too difficult.
