Gelatin Doesn't Cure Brittle Nails

In the 1890s, Mrs. Charles Knox was tired of making gelatin by boiling left-over slaughter-house waste of cow's hooves, feet, bones, tendons and skin. Her salesman husband taught her how to make dried sheets of gelatin and then grind them to a powder.

They decided to go into business together to sell gelatin, but powdered gelatin will not sell well unless you can find a particular use, such as curing a disease or condition. The resourceful Knoxes advertised that gelatin contains protein and lack of protein causes deformed dry nails. So they claimed that gelatin can be used to treat thick, dry, deformed nails and the results are history. Gelatin contains protein, but lack of moisture, not protein, is the cause of brittle and cracked nails. The most-effective treatment is to paint nail polish to slow the loss of moisture. You can still buy Knox's gelatin and people today still think that gelatin can be used to treat deformed nails.  See Rose Knox: Profit from Brittle Nails
