Okay, so growth has definitely taken place in these past two months, but can the peppermint oil really be held responsible? The growth I retained was about an inch--correct me if I'm not seeing right. An inch is perfectly normal in this amount of time. I also suspect that it was the peppermint oil that was causing my scalp to flake up. I went this last week without oiling and the flakes dramatically decreased. I'm not 100% sold on this, but at least I see that my hair is growing at a good rate!
