Eyebrow growth?

So I've been growing out my eyebrows since January.  Some of the hairs have grown back but the ones that I want to grow back or just NOT growing back :(  I'm assuming I have stunned the growth we overplucking and waxing.  My eyebrows are pretty thin and want them to grow in thicker.  How long is the normal eyebrow growth process?  I have used rogaine, billion dollar brows and now I'm using castor oil lol.  Any input out there?  thanks!!!

I'm using castor oil as well....I'm noticing a slight difference.  My mother swears by carrot oil.  I've also heard that Jamaican Black castor Oil works better than regular castor oil. HTH

i heard if you shave ur eyebrows they start to grow back...i use to know someone that went to a lady that would do her eyebrows and what ever part that didn't grow she would shave it and she said that it was helping 

I could send you some of mine. I get a unibrow easily. :(

I have my barber trim them every so often and I have to carefully shave the middle.

Sorry I'm not any more help.
