10 Best Sulfate Free Shampoo Reviews and Buyer’s Guide

Sulfate-free shampoos, what are they and what does it really do for our hair? 

Nowadays, there are so many different shampoo brands and hair care products to choose from. Anti-dandruff shampoos? Tons of that. Anti-fungal shampoos? Many drugstores carry that. Beard shampoos? You don’t need to go to a salon to pick up one! But, here’s one of the controversial products in the game: Sulfate-free shampoos. 

In this article, you’ll get to know more about sulfate-free shampoos and you get to decide if it’s time to get one for yourself!

But first, What are Sulfates in Shampoo?

Sulfates are a type of surfactant (emulsifier, and/or foaming agent) that cleans and removes dirt from any surface. In comparison to other cleansing ingredients mixed in shampoo, sulfates are known to have the deepest cleansing effects. They belong to a group of cleansers called anionic surfactants, which clean away substances. Because of this, sulfates are not only used in shampoo but are also found in household cleaners and detergents.

Types of Sulfates in Shampoos

Sulfates can be easily found on the ingredients list of many shampoo brands. While their names can sound intimidating, it’s still important to be familiar with some sulfates! That is, if you want to know what you’re putting on your hair.

The two most-commonly known sulfates in shampoos are: 

Sodium Lauryl Sulfate

Also usually referred to as SLS, Sodium Lauryl Sulfate is used in low concentrations and is one of the most common sulfates found in hygiene products. SLS works to trap oil and debris in the hair so it can be cleaned thoroughly. SLS can be found in large concentrations in items like industrial cleaners like floor cleaning solutions and car wash products. This chemical is also a good foaming agent and helps products achieve a foamy lather as seen in toothpastes and shampoos. The Food and Drug Administration (FDA) also includes SLS on its list of multipurpose additives that are safe to add to food items.

Sodium Laureth Sulfate

Despite sounding similar; Sodium Laureth Sulfate (SLES) and Sodium Lauryl Sulfate (SLS) are different. SLES is a relatively milder cleansing agent due to a higher amount of fatty alcohols which has a different chemical structure. It can be found in hair products, oral care, and other skincare products. Because the fatty alcohols found in this sulfate act as good emollients and thickeners, SLES also has effective foaming properties. This, therefore, causes the classic sudsy and bubbly lather we’re used to seeing on hair care products. 

Why Should You Avoid Sulfates?

The popularity of Sodium Lauryl Sulfate(SLS) and Sodium Laureth Sulfate(SLES) has been diminishing over the years due to reports of their adverse side effects. It also may contain 1,4-dioxane, a contaminant in SLS production that has been found to be carcinogenic to humans.

In fact, the 1983 Safety Assessment Report of sodium lauryl sulfate and ammonium lauryl sulfate stated that SLS has denaturing and degenerative properties that can affect cells and can penetrate skin and scalp if used in high concentrations. Included in the report were SLS animal studies and the side effects observed were depression, labored breathing, diarrhea, and death.

On the other hand, human studies showed milder side effects. It was found that skin irritation was directly proportional to the concentration used. Additionally, it was concluded that SLS (and ammonium lauryl sulfate) appear to be safe if used briefly and washed off thoroughly.

Because of these possible side effects, more and more people are avoiding sulfate shampoos and other sulfate products.

So, what is a Sulfate-Free Shampoo?

Sulfate-free shampoos are simply shampoos free of any sulfate. Instead of SLS and SLEs, they are infused with non-sulfate surfactants that are more gentle in nature. Since most sulfate-free shampoos are dedicated for people with sensitive skin they are also paraben-free, silicone-free, and sometimes vegan and cruelty-free. 

Sulfate-Free Shampoo Ingredients

Sulfate-free shampoos today mostly contain mild surfactants like amino acids and fatty acids from coconut oil and palm oil. They are most commonly known as amino acid surfactants. Some SLS-free shampoos also use sugar surfactants obtained from corn and other plants that have very similar structures and functions as amino acid surfactants. 

Ester and the carboxylic (or amino) acid groups of chemicals are also good alternative surfactants because they contain a long chain of carbons that can also trap dirt, lipids and oils. Surfactants function by reducing the surface tension, or affinity of dirt to surface by forming micelles (oil trapping mechanism of surfactants).

 Here are more mild non-sulfate surfactants used in the cosmetic industry along with their sources.

Best Non-Sulfate Surfactants

  • Decyl glucoside: Glucose from corn starch, coconut and/or palm oil
  • Caprylyl capryl glucoside: Glucose from corn starch, coconut and/or palm oil
  • Sodium cocoyl glutamate: From coconut oil, corn, and fruit sugars
  • Disodium laureth sulfosuccinate: Derived from fatty alcohols in beef fat, fish oil, and olive oil
  • Sodium methyl oleoyl taurate: Partially derived from coconut and palm kernel.
  • Sodium cocoyl isethionate Derived from coconuts, specifically coconut oil
  • Sodium methyl cocoyl taurate Derived from coconut
  • Cocamidopropyl betaine: Derived from coconut/palm oil fatty acids
  • Sodium lauroyl lactylate: Derived from coconut oil
  • Sodium lauroyl glutamate: Derived from corn

How do Sulfate Free Shampoos Work?

Sulfate-free shampoos work just like any shampoo, they remove dirt and oil from the scalp and hair. The only difference is it doesn’t lather unlike shampoos with sulfates.

Why use Sulfate Free shampoo?

As mentioned above, sulfate shampoos may cause mild skin irritation to more servere allergic reactions. Other than that, there are a lot of other reasons why you should sulfate-free shampoos. Use sulfate shampoo if:

You have colored and/or salon-treated hair!

These days, still buying sulfate-containing products when you’ve been at the salon is considered a rookie mistake. Using sulfate-containing shampoo on color-treated hair can be too strong and will likely strip the color off too quickly. Other chemicals from salon services such as hair spa, hair relaxing or rebonding may also be removed by sulfates.

Your hair is dry and/or frizzy.

Sulfate-free shampoos maintain the natural oils on the scalp and hair, which ultimately leaves your hair with more moisture. According to the American Academy of Dermatology (AAD) using shampoos that are formulated with strong sulfates can be drying to some hair types. This is especially true for ethnic hair and non-straight hair. If even after long usage of regular shampoos your hair is dry and frizzy, maybe give sulfate-free shampoos a shot!

You have a sensitive scalp or skin.

If your skin and scalp are on the sensitive side, the AAD says that using shampoos that contain sulfates may irritate your skin. Using a gentler sulfate-free shampoo can help in these times. However, if there’s excessive itching, flaking, or alarming red blemishes on your scalp and around your head, consult a dermatologist!

Your hair is damaged!

Your hair is fragile or damaged by continuous coloring, salon treatments, sun exposure, hair loss, and a myriad of other reasons. If that’s the case, the sulfate-free shampoo will be your best bet! Sulfate-free shampoos are gentle enough to not make the situation worse, so whatever moisture your hair still has left on its remains. At least, this gives your hair some much-needed rest and leeway from all the chemicals you’ve been dealing with.

You want to switch to more eco-friendly shampoos.

Sulfates have always been very controversial, but perhaps their environmental concerns are the ones that take the cake. SLS can be made from petroleum oil, coconut, or palm oil. Meanwhile, SLES comes from either palm or coconut oil only, which has led to several debates. These sulfates are cost-effective for many manufacturers because of the versatility of their sources, especially when prices of various oils fluctuate in the world market. Reports have shown that the deforestation of many lands inhabited by endangered species has been caused by palm oil production. Consequently, concerns for ethics and the environment have come up.

Problems with Sulfate Free Shampoo

You might be thinking to yourself, ‘Sulfate-free shampoos have so many pros!’. However, we also want to be the ones to tell you that this product isn’t entirely perfect. Sometimes, it may also be not the right fit for you or your needs. You don’t necessarily need sulfate-free shampoos if:

Your scalp is oily.

If you have an oily scalp, sulfates might still be your friend in thoroughly cleansing your head. Sulfate-free shampoos won’t be able to absorb the oils on your scalp, nor ease the greasy feeling.

You’re having dandruff and other debris on your scalp.

For those looking for a deep clean that erases even the smallest traces of dandruff, sulfates are what you need. Sometimes, even dandruff combs and shampoo brushes aren’t enough to give your hair justice. Sulfate-free shampoos will also be too mild to fully give your scalp the cleansing it needs. 

Sulfate free shampoo doesn’t lather

Some people just love their foamy bubble baths and creamy, fizzy shampoos. Others don’t feel clean and comfortable at all if there are no bubbles to be seen as they rub their hair with the product. If that’s the case, then sulfate-free shampoos won’t be the best for you, since it has zero to no lather at all.

Your hair is just thicker and longer.

Sulfate-free shampoos can also require more than one wash if you have long or thick hair. As a result, you end up using larger amounts of shampoo to get the job done. That can be quite a hassle if you’re also on a tight budget.

You’re running on a tight schedule!

Because it’s harder to tell whether you’re cleaning your hair thoroughly or not, using sulfate-free shampoos can make you last longer in the bathroom. This is especially inconvenient if you are in a rush and there is still some grease left in your hair unremoved.

How to Wash Hair with Sulfate-free Shampoos

Using sulfate-free shampoo is similar to using regular shampoo.

  1. Rinse your hair thoroughly.
  2. Apply a small amount of sulfate-free shampoo to your hands. Use more water than shampoo, and work the shampoo through your hair.
  3. If you feel the need to, you can rinse, then shampoo again – but up to twice only.
  4. Rinse and follow up with other hair care products, like conditioner.

FAQs about Sulfate Free Shampoos

What are the side effects of sulphate shampoo?

Sulfate shampoos can strip oil and moisture from the scalp causing mild side effects like redness, itching, and swelling. Make sure that you rinse your scalp thoroughly to avoid prolonged contact with the sulfates in your shampoo.

What are sulfites in shampoo?

Sulfites are natural preservatives that can be used in food or hair and skincare products. They are usually used in preserving cosmetic formulas like hair colors and bleaches. They are strong anti-oxidants and may cause allergic reactions if used in large concentrations.

Do sulfate-free shampoos lather? 

No, they don’t. This is due to the lack of SLS and SLES.

Does Sulfate Free shampoo cause hair loss?

No, sulfate-free shampoos don’t cause hair loss. If you’re experiencing hair loss after using a sulfate-free shampoo, change your brand and consult your doctor.

Do sulfate-free shampoos remove silicone?

Yes, they do. Sulfate-free shampoos are specially formulated to remove contaminants, including silicone.

Do sulfate free shampoos cause dandruff?

No, they shouldn’t unless you have an allergy to the natural ingredients. If you experience increased dandruff after using sulfate-free shampoo, switch the brand of shampoo you’re using. Additionally, if your hair is not washed and cleaned thoroughly, you may experience dandruff and product build-up over time.

How can shampoos be sulfate-free but still list sulfates as ingredients?

“Sulfate-free” products are technically just those without SLS or SLES. They can still use other, milder sulfates as cleansing agents. If you want a really sulfate-free shampoo, you’ll need to actively check each shampoo’s ingredients.

Is T Gel Sulfate free?

Neutrogena’s T Gel shampoo is not a sulfate free shampoo. This shampoo is formulated for people with dandruff that’s why it contains stronger surfactants like Sodium Laureth Sulfate to help remove dirt and product build-up.

Is Viviscal Shampoo Sulfate Free?

Viviscal is not a sulfate free shampoo. It contains Ammonium Lauryl Sulfate a strong sulfate surfactant that can cause mild to moderate skin irritation.

How to Check if Shampoo is Sulfate Free?

Most sulfate free shampoos will include a “sulfate-free” note and indication in their labels. If this is not included, there’s a big chance that the shampoo is formulated with SLS or ALS.

Bottomline

Sulfate-free shampoos do you some good, while sulfates in shampoo can still help you in certain situations. Neither will cause your hair problems, so it’s really just a matter of looking out which one between sulfate-free and sulfate-containing shampoos suits you.

While there are significant differences between the two, these don’t necessarily make one kind ultimately superior over the other. So check out all the info that we’ve selected and listed down for you, and make a balanced decision about what’s best for your hair!
