[General Anime] Why is it whenever someone gets stronger, their hair grows in length?

Is it just apart of becoming stronger, or is there some deeper level connection between hair lengths and strength?

Most anime powers run off of some form of Chi/ki/qi/etc, all of which can be roughly defined as "Life Energy". When someone gets more powerful, this life energy starts flowing through all of their systems, enhancing them exponentially. Hair being one of the fastest growing things on your body already, goes even faster when the follicles have been supercharged.
