Has it's drawbacks but seems to help some regrowth
This does seem to encourage eyebrow growth, though no miracles.  It takes repeated use.  It is easy to get oil on sheets or anything that comes in contact with your eyebrows.  I've had a few of these.  Two things I can't stress enough:  when the little rubber washer falls down around the applicator brush DO NOT THROW IT AWAY.  Push the rubber ring back, because without it the bottle leaks oil whenever it's not straight up and down.  Also THE BOTTLE IS MADE OF GLASS.  After having one roll off the vanity and break on the bathroom floor, flinging oil everywhere, I replaced it and the first thing I did was create a bubble wrap 'holder' (cardboard on the bottom to allow it to stand up and bubble wrap on the sides) to prevent it from happening again.  It's a hassle, and the results are not magic, but with consistent use it does appear to help bald patches in eyebrows grow new growth.
