hi,just saw this,well i've never had extensions, but i know that if you have your hair in a tight pony tail or anything it tends to break and fall out. if i were you i would really be gentle to my hair for awhile(deep condition,use a pick or wide tooth comb when it's wet).i wouldn't do anything to pull or cause more damage.if you can't stand it, maybe check out wigs or hair pieces and wear in a loose ponytail.well good luck.it might take a couple of yrs. for your hair to be back completely.
