How Sulfates Affect your Hair Extensions and Why Use Sulfate-Free Shampoo

What are sulfates, and what makes a sulfate free shampoo so healthy? As you walk down the shampoo aisle in Ulta, you may notice many shampoo bottles that read, “Sulfate-Free.” Lets learn exactly what this mean...

What are Sulfates?

Sulfates are a popular ingredient in detergent, hand soap, body wash and shampoo. Sulfate is what causes the foaming lather that we all love. Sulfates are all primarily surfactants. A surfactant is a combination of molecules that attract both oil and water. One molecule clings to oil while the other clings to water, allowing the grease and dirt to release from you there and flow down the drain. Unfortunately, studies have linked sulfates to some pretty gnarly consequences. Some reviews have related sulfates to cell damage in the hair. Although sulfates have been deemed “safe in low quantities” by the Food and Drug Administration, studies conducted by the American College of Toxicology found that concentrations above 1% over continued use did cause cellular damage. Most shampoos have a concentration at a whopping 15%.

How Does This Affect Me?

If you have sensitive skin, you’ll want to avoid using sulfates to shampoo and condition your hair. On skin disorders such as eczema, psoriasis, or any other skin disorder, sulfates may encourage a flare-up. If you have dry hair, using a sulfate shampoo will encourage your hair to be drier because sulfates strip the hair of its natural oils. For those that like to experiment with color, a sulfate-free shampoo can help maintain your color and prevent it from fading.

How Sulfates Affect Hair Extensions

Using a sulfate shampoo on your hair extensions is even worse than using it on your natural hair! Sulfates are harmful to your hair extensions because human hair extensions are not attached to a scalp, so no natural oils are being transferred to the hair shaft. Once the sulfate comes in contact with the hair extension, it strips all the oil and moisture from the hair. Lack of oil and moisture encourages frizz, tangling, and breakage. Choosing a sulfate-free shampoo and conditioner is imperative to maintain the health of your hair extensions. Even though sulfates aren’t good for your health, we are bound to come in contact with them eventually. We can avoid using them in our hair; here are some alternatives to sulfate shampoo.


The co-wash craze emerged from the natural hair community. When curly –headed women discovered the harms of sulfate shampoo, they started cleansing their hair with sulfate-free conditioner. This method provided them moisture, easy-detangling, and soft, clean hair. Now there is cleansing conditioner available for purchase. These cleansing conditioners are regular conditioners fortified with cleansing agents that clean and moisturize the hair simultaneously. Cleansing conditioners are great for curly hair extensions. Using a cleansing conditioner on straight hair extensions may weight them down due to excess oil. Here are some products that you can use to co-wash:

Tips for Washing Your Hair Extensions

Now that you’ve gone out and replaced all your damaging sulfate shampoos with healthier moisturizing sulfate-free alternatives, I bet you’re super excited to try them all out. Before you hop to it, here are some tips for washing your hair extensions properly to prevent tangling and breakage. Before immersing your hair extensions into the water, thoroughly detangle the hair from tips to roots with a wide-tooth comb. When cleansing your hair extensions, always use lukewarm water. Using lukewarm water opens the cuticle without encouraging tangles. One the hair is thoroughly saturated with water, wring most of the water out. Then use a palm-sized amount of your favorite sulfate-free shampoo to remove any dirt, oil, and product build-up. I always recommend using two lathers to ensure you remove all impurities. During a lather, be sure to finger comb the hair downwards to prevent tangling. After you thoroughly rinse the shampoo out, wring the excess water out to prepare for conditioner. A great sulfate-free conditioner to use is It’s A 10 Miracle Daily Conditioner or Redken Extreme for color-treated extensions.

Make Sure to Condition

To ensure your extensions absorb the conditioner into the cortex and reap all the benefits, place your conditioner-saturated extensions in a plastic grocery bag. Place the bag in a bowl/tub or hot water. This bagging method will open the cuticle of the hair shaft and allow all the moisture and protein to penetrate the cortex. After the conditioning process, I love to use 100% pure Argan oil on my extensions before I blow dry. Argan oil adds beautiful shine and keeps the ends healthy. Now that we know that sulfates are not only harmful to our hair extensions, but also our natural hair and health, its time to throw out the bottles of harsh shampoos! I challenge you to test out one of the sulfate-free shampoo options mentioned earlier and build a new hair care routine for your extensions and your natural hair.
