I had razor bumps on the back of my head for years, since college, playing football. Everything I used for years, never did anything. I purchased this set at Sawgrass Mall, and didn't think it would work. But it did. It cleared up my razor bumps and my hair started to grow. I will never buy anything from the store again. Only this works. The oil has a strong smell or oregano, but I don't care... it works.
