While both products may be good in theory, are they both suitable for the same job? According to Shampoos Hub, one pro for baby powder is that its oil absorption is completely on par with dry shampoo, and they cite that some users couldn't tell the difference between using baby powder and using dry shampoo. However, there's a considerable con when using baby powder. Some baby powders include talc in them, which some scientists believe to be carcinogenic (via Shampoos Hub). This means that extended exposure to this could increase your chances of becoming seriously sick.

Not all baby powders house this ingredient, though, so you want to be on the look out for it when purchasing your baby powder. According to Beautylish, one reason to buy baby powder is because it's cheaper than dry shampoo, but accomplishes the same goal. And washing your hair in the shower less means you can maintain a dyed hair color or just overall keep your scalp from drying out. They recommend spreading baby powder evenly across your hands by putting some in one palm and then rubbing your hands together to disperse it. Then, begin at your roots and rub the powder into your hair.

Ultimately, you want to look at the ingredients of the products you're using, just like with any other beauty product or even food.
