Is Salt in Shampoo Bad for Hair? What You Need to Know About Sodium Chloride

You’ve heard the phrase “you are what you eat,” but what about what you shampoo with?

At Kenneth’s, we’re kicking off a fresh campaign to clear up a commonly misunderstood, but highly important ingredient that shows up in many drugstore and grocery store shampoos: sodium chloride. Also known simply as salt, this additive may be great on fries, but not so much on your follicles.

What is Sodium Chloride Doing in Shampoo?

What is Sodium Chloride Doing in Shampoo?

In many commercial shampoo formulas, sodium chloride is used as a thickener. It makes liquid products look creamy, rich, and uniform, often at the expense of your hair’s health. It’s inexpensive and widely available, which is why it’s often found in lower-cost, or mass-produced haircare products.

The problem? It’s abrasive, drying, and often works directly against the results you’re investing in at the salon.

Why Salt is a Red Flag

Sodium chloride may sound harmless, but here’s what Irma Jobst, our chemist and private label partner, shared during our recent product knowledge seminar:

Don’t use any sodium chloride if you really want your hair to grow long.

Why? Because sodium chloride can:

  • Strip hair color by lifting the cuticle and allowing color molecules to escape
  • Weaken keratin bonds, which are essential for strength, smoothness, and elasticity
  • Cause dryness, brittleness, and irritation, especially for those with sensitive scalps or processed hair
  • Interfere with in-salon treatments, especially keratin, color, and smoothing services
  • And worst of all? It can slow your length goals by weakening hair at the root and along the shaft

In other words, that “bargain” shampoo may actually be costing you more in color longevity, styling time, and hair health than you realize.

The Kenneth’s Difference: No Salt, No Compromise

The Kenneth’s Difference: No Salt, No Compromise

Every shampoo in our Kenneth’s private label line is consciously formulated without sodium chloride. Instead, we use modern ingredient technology designed to:

  • Maintain your hair’s natural pH
  • Protect your professional color between visits
  • Support scalp health and hair growth
  • Work with your services, not against them

These shampoos aren’t repackaged stock; they’re designed from the ground up exclusively for Kenneth’s. And because our technician’s input and testing impacts the formulation, we can ensure each bottle reflects the same care and intention you’ve come to expect in our salons.

Not One Size Fits All. And That’s a Good Thing

Person Shopping For Kenneth's Shampoo

We offer a shampoo for every concern, from hydration and volume to color-locking and bond-repairing. And just like you change your wardrobe with the seasons, it’s smart to switch up your shampoo as your hair changes with the weather, a new cut or color, or even hormonal shifts.

If you’re unsure where to start, your stylist is your best resource. Let them know your current hair goals, and they’ll help you find your best seasonal match.

Let’s Talk Shampoo. Seriously.

Next time you visit, take a look in the mirror, literally. Our “No Salt” mirror clings are meant to spark a conversation. If your shampoo contains sodium chloride, it might be undoing all the magic we’re working so hard to create.

Ask your stylist which Kenneth’s shampoo is right for you today, and for the hair you want tomorrow. You can pick it up in the salon or order it online anytime.

Because your hair deserves more than table salt.

Ashley always does a fabulous job! I love how she layers my hair so effortlessly! I will always book her only for my hair cuts!
Sarah Baran
I tried Anna at the last minute when my regular stylist was out sick. Anna was super! I received a couple of compliments over the Christmas family gatherings that my hair looked really good. Thanks Anna!
Izzy Vitanovic
I had a haircut and a vital shot about a week ago with Suzanne, and as always, she was amazing! I’ve been going to her for almost a year now, and she is consistently kind, knowledgeable, and so easy to trust with my hair. Even though her level of experience may cost a bit more, she is so worth it. Suzanne makes sure you are well informed every step of the way, she explains what she’s doing, why she’s doing it, and walks you through the haircut so there are no surprises. She also takes the time to teach you how to recreate the same style at home, which I truly appreciate. After having some hair nightmares at other salons in the past no matter how upscale they are and , it’s such a relief to finally have a stylist who truly knows hair and cares about her clients. I always leave feeling confident and happy with my hair. Highly recommend Suzanne!

I just had a haircut with Ally, and she was very friendly and professional. There was no waiting at all. I liked my haircut at the salon, and I liked it even more when I checked it again at home. I’ll definitely book my future haircuts with her. The receptionist at the front was also very friendly.
