because its to tight and your brushing to hard and its irrating your scalp.
It is too tight or either their hair is too thick/long and this makes the ponytail too heavy.
That always happens to me! Even if my pony tail isnt tight I will get the nastiest headache and my scalp will ache.. Maybe it is because of pressure? I dont know but its werid because sometimes it happens and sometimes it doesn't.. I dont know if this plays a factor or not either but I do suffer from migranes and have been prescribed prescription meds from the MD when one does come along
