Almost every single shampoo and conditioner you will find at your local store will include sulfates on their ingredients list. Sometimes they will be listed as sodium lauryl sulfate or laureth sulfate, and it is a compound that not only attracts dirt and oil and removes it completely from your scalp, it is also the reason why your shampoos and shower gels get foamy when you rub it in.
Sulfates aren’t necessarily DANGEROUS, per se, however, because they are so effective at lifting dirt and oils out of your hair and scalp, that can lead to a huge moisture imbalance, and that will affect the amount of oil your body produces, and sometimes the texture of your hair (hellooooo, frizz!).
Choosing a shampoo and conditioner pair that is 100% sulfate-free is a smart move for the long-term care of your hair because it will get your hair clean without stripping it of the things it needs to keep your scalp healthy. It’s recommended for people with frizz-prone hair, color-treated hair, coarse hair, and damaged hair, which covers basically all of us.
A sulfate-free shampoo will remove the dirt and oil that is making your hair dirty but help your hair retain the natural level of moisture it requires to stay healthy. Over time, you’ll start to notice that your hair is growing out in better condition than it used to before you made the switch; which is a huge payoff for the small sacrifice of having a shampoo that doesn’t get foamy like you’re used to.
