If you're someone who takes a look at the ingredients list of the products you purchase, you're on to something. Cosmetics, in particular, are not approved by the Food and Drug Administration (FDA), so it's possible that questionable ingredients might find their way into the products you use on your hair and body regularly.

One such ingredient is known as sulfates, or chemicals in shampoos and other cleaning agents that help rid the skin and scalp of oil and dirt. On product labels, they're most commonly found under the names sodium laureth sulfate, sodium lauryl sulfate and ammonium laureth sulfate.

"Sulfates work to cleanse and lather hair, but they can sometimes leave mild, undesirable side effects such as color-fading, dryness, brittleness and redness to the scalp," explains Dendy Engelman, MD, cosmetic dermatologist and Mohs surgeon at Shafer Clinic in New York City. "When a shampoo is sulfate-free, it does not contain any of these cleansing chemicals, which is usually best and safest for your hair."

The good news is that more and more hair care brands are formulating their products to be made without sulfates, which is especially convenient for those with sensitive skin, a dry or sensitive scalp or dry or brittle hair.

Opting for a sulfate-free shampoo can also be beneficial for people with color-treated hair to help preserve their hair color for longer, says Marisa Garshick, MD, a dermatologist at Medical Dermatology & Cosmetic Surgery in New York City.

What to Know Before You Buy a Sulfate-Free Shampoo

Here are some features to look for when shopping for shampoos without sulfates.

1. Ingredients

There are many variations of sulfates, but the two main types Dr. Engelman suggests looking out for on ingredient labels are sodium lauryl sulfate (SLS) and sodium laureth sulfate (SLES).

She also recommends avoiding any other potentially damaging chemicals like parabens, silicones, etc., as they are known to weaken hair over time and hinder its growth.

2. Hair Type

New York City-based trichologist and hairstylist Penny James recommends shopping for sulfate-free shampoos as you would regular shampoos: by your hair type.

"If you have thick, kinky hair, look for a sulfate-free shampoo that still has hydrating ingredients like coconut oil-acid," she says. "If you have thin hair and an oily scalp, look for a shampoo with volumizing ingredients like magnesium and biotin."

3. Eco-Friendliness

Some manufacturers offer shampoo refills that reduce the use of plastic packaging, making them more eco-friendly, Dr. Camp says. If you're someone with an eye on helping the environment, making smart purchases in terms of zero-waste products can go a long way.

4. Price

When deciding how much to spend on a product, Dr. Camp suggests considering how often you will use it.

"If it is something that you will use frequently and need to spend money on often, it may make more sense to purchase a less expensive product than, say, one that you do not use as often and may last longer," he says.
