Exactly 3 months ago I started applying castor oil to my eyelashes twice a day to see if it would help them grow, and I think it's worked - I don't have luscious lashes but they are visibly longer (see pic). I started the experiment after a friend started using Revitalash and saw some results after 3 months ... I wasn't going to fork out for Revitalash but I already had the castor oil knocking about. I don't think I noticed any difference until the 3 month mark but I'm going to carry on and see if things improve further.
I made the pic B&W because I thought the close up eye pic was a bit creepy!
