A: You already know that Coca Cola can be used for a number of things, from cleaning your toilet to increasing your low blood pressure, and it seems that curling your hair can be added to the list of thing Coca Cola can do. However, the truth is that Coke doesn’t really make your hair curly, it just brings out the natural curl in your hair and just shapes it to look prettier.
Here’s the secret: Coca Cola contains phosphoric acid, which means it has a very low pH level (Coca Cola Classic has a pH of 2.5). Since it’s acidic, it contracts the hair follicles when it’s applied to the hair, and makes the hair look shiny and smooth. This also means that the hair (hair prone to curling in particular) will have its natural curl enhanced. So when you apply it to your hair, the follicles tighten, which makes your strands look smoother and your curls look more defined. Some even say that the high levels of sugar it contains makes your hair look more voluminous.
All you have to do is rinse your hair with Coca Cola. It can even be flat because the carbonation doesn’t make any difference. Leave it on for 5 to 10 minutes and wash it like you normally do. You have to remember to wash your hair with shampoo after the Coca Cola rinse because the high levels of sugar it contains can make your hair all sticky and leave behind a crusty residue.
