I've been trying to grow my eyebrows out for FOUR years. No joke. I last plucked them in 2017. And they are still really thin and sparse :( I've tried everything, castor oil, argan oil, taking vitamins, other various growth serums and literally nothing has worked. I've also noticed any new growth i get falls out after a couple of weeks and the new hairs are really thin? PLEASE give me suggestions on what i can actually do to help them grow??? They used to be really thick before I ever plucked them so absolutely kicking myself now.
