I would have said waist length but it seems thus far in measuring, (which was not good measuring at all, rather hasty and not a full month or a complete flat iron of my lengths), so far I am sure my hair grows at the least .5 inches.... I am going to remeasure wants I hit a full month and press and flat iron correctly.
With that being said according to my calculations I will only be at midback and super close to waist length next year if my hair only does grow at .5 per month, but it could be more....
