I dont know how old you are but it could be a number of things, Have you ever had any blood work done to check for your thyroid and hormone levels, Have you ever been to a dermatologist to check into your problem, They can tell if you have alopecia and what kind it is, The main one is female pattern baldness, Have you ever thought of buying a half wig, It would cover your thinning spots only and not be a whole wig, There are alot of videos on Youtube about hair loss and what other women have done, I have heard once you start using that medicine you have to use it the rest of your life
