The best thing about this miracle hair-growing hat from the June, 1928 edition of Popular Mechanics is its fez-like character. It conveys an attitude of such perfect charlatanry.
This new invention–the result of an experience gained in treating thousands of cases of baldness–is in the form of a new kind of hat. It is worn on the head just 10 minutes a day. No unnecessary fuss of any kind. Just put the hat on your head. Wear it 10 minutes. And that's all there is to it.
Sounds impossible, doesn't it? All right. Then let me emphasize this fact. I don't care how thin your hair is. I don't care how many treatments you have taken without results. Unless my discovery actually produces a new growth of hair on your head in 30 days, then all you need do is tell me so. And without asking one question, I will instantly– and gladly–mail you a check refunding you every penny you have paid me.
