I know a problem with some guys are their eyebrows and how thin they are from tweezing them as girls.
Well I figured I'd drop by with a tip since I've also been growing out my brows(from my crazy over tweezing)
It's called Castor Oil.
There's lots of beauty forums out there that swear by this stuff, I'm also putting in my word too.
It really does work! It's super cheap.
All you do is every night apply the oil generously on your brow area after you've washed your face.
It takes time for them to grow back but they will grow back thicker and fuller.
It only works if you have hair follicles there, keep that in mind. I know that when you try to grow your eyebrows back on your own they come back hairy but not as thick and full as they were before. But the oil really will help you.
You can find castor oil at any pharmacy, it's cheap and it works!
You just have to be patient! And do not stop applying
