Best Sodium Chloride-Free Shampoo of 2025

"I was advised to use this product due to my hair color, and it helped with my dermatitis. I used to struggle with other shampoos, but after using this one, my skin irritation disappeared. I just make sure to create a foam with my hands before applying it to my scalp, and it leaves my hair with a lovely shine."

"I've found the shampoo to be a bit too watery. It doesn't lather well unless I use a lot of it. I can't recall this issue from my previous experiences with it. Unfortunately, it's too late for me to return it since I bought it a couple of months ago."

"This product is fantastic for my family! It's a great value, and we appreciate that it doesn't contain any harmful ingredients. My hairdresser introduced us to it, and now we can't imagine using anything else."

"I've been using this product for over years and have never been disappointed. My hair has many chemicals on it, and this shampoo keeps it smooth and in good condition."

"I've only used this shampoo a few times, but it's a good one. However, I feel that any sulfate-free shampoo doesn't quite make my hair and scalp squeaky clean. Still, it has a pleasant smell."

"I did a keratin treatment with the same brand and decided to try their shampoo. I like the smell, but it does feel a bit dry and creates almost no foam."

"I really appreciate the high quality materials used in this product. It feels sturdy and well-made."

"Their customer service is outstanding! They respond quickly and resolve issues efficiently."

"The stylish design fits perfectly with my home decor, and I love how it looks."

"I've struggled with frizzy hair for ages, but after using this shampoo, I noticed a significant change from the very first wash. My hair feels smoother and much more manageable. Though it is on the pricier side, I truly believe it's worth every penny!"

"I love this product! It leaves my hair so soft and the wonderful scent makes it even better. However, I recently discovered that it's not cruelty-free, so I'm hesitant to continue using it. I'm hoping to find out if there have been any changes regarding that."

"As someone with curly hair, I find this product to be a game-changer! It not only helps with heat protection but also keeps my hair from getting frizzy in humid weather. I definitely recommend pairing it with the heat cream for even better results!"

"Since moving to warm and humid Florida, I’ve been using the color lock treatments for my curly, frizzy short hair. I’ve always hesitated with regular keratin treatments, but this one has made my hair so much easier to manage. I even skip blow drying sometimes! I found this shampoo on Amazon, and it’s clearly extending the life of my treatments."

"I alternate between this product and Joico Color Endure Violet shampoo, which smells amazing and eliminates unwanted brassy tones effectively. The more purple the shampoo, the better it works for me!"

"I bought this shampoo for my keratin color lock treatment and was disappointed. My hair felt like a tangled mess, and I couldn't comb through it. While the product may lack necessary conditioners, I absolutely recommend the Simply Smooth Magic Potion—it has completely revitalized my hair!"

"As an avid Amazon shopper, this is my second review in years. After a terrible experience with a blue shampoo that ruined my balayage, I sought a solution. I found this combo of shampoo, conditioner, hair mask, and drops on Amazon, and it has been a miracle in a bottle! My hair is now soft and shiny!"

"I've been using Keratin shampoos for years and discovered Natural Formula while visiting Israel. I was thrilled to find it on Amazon! Now, I use it regularly, and I'm very happy with how it keeps my hair shiny, soft, and straight. The great smell is an added bonus!"

"Initially, I was hesitant to try a new brand. However, the affordable price encouraged me. I'm glad I did because this product did not disappoint! You only need a small amount, and my hair looks fantastic with a wonderful scent! Plus, the quick delivery was a pleasant surprise!"

"For anyone with a keratin treatment, this is the best shampoo ever! It smells wonderful, is reasonably priced, and leaves my hair feeling healthy, shiny, and soft!"

"I have a lot of straight hair and have been sharing this product with my husband for months. One bottle has lasted us a long time! I highly recommend it!"

"Initially, I bought this shampoo for my wife, but now everyone in the family uses it, including my teenage daughter. We have tried various salt-free shampoos, and this one works the best for our different hair types, leaving us feeling clean and soft. I’m looking forward to trying Damila’s conditioner next!"

"As I've aged, my scalp became excessively dry, and I could only use baby shampoo, which made my hair drier. After trying this shampoo for a couple of months, I’m thrilled with how it keeps my scalp and hair soft. I’m saying goodbye to baby shampoo for good!"

"This shampoo is fantastic! It delivers on its promises and leaves my hair super soft, shiny, and manageable. I absolutely love it!"

"I think this shampoo is pretty good. I use it after my keratin treatment to wash my hair."

"I've found this product to be one of the best I've ever used. My thinning, baby fine hair has really benefited from it, adding volume and body that lasts 3-4 days!"

"I did not experience any volume at all. The pump was broken and I would not recommend it."

"I’ve used this shampoo for years and absolutely love it. However, my last order felt watered down, requiring me to use 3-4 pumps instead of one. It's disappointing, and I won't order from this seller again."

"I ordered this shampoo for my daughter, who has long, dry, and frizzy hair. It definitely helps reduce frizz, and her color has remained vibrant. While I didn’t see dramatic health improvements yet, her hair looks much better. It's a bit pricey, but I believe this bottle will last a long time, which makes it reasonable."

"I find this shampoo to be quite nice. It leaves my hair silky and smooth, and I haven't noticed any color stripping, even with hard water. However, I feel the price is a bit steep at $70. It's decent, but I think I'd prefer to spend $30-$40 instead."
