Curly hair issues occur because of several factors, but when you struggle to pinpoint the problem, it generally indicates build-up from products, hard water, and dirt in your scalp and hair. The best way to fix this is with a chelator.

A chelating shampoo is a deep cleanser for the hair and scalp that effectively removes the buildup of dirt, minerals from hard water, salt, chlorine, product residue, and other oils and gunk that accumulate over time. It is a product used one to two times a month to help hair health.

If you are looking to clean, refresh, and bring back life to your lackluster hair with a chelating shampoo but don’t know where to start, this post has everything you need to know and more to get you started and help you nurse your curls back to health (or just maintain them!).

What Is A Chelating Shampoo?

A chelating shampoo is a type of hair shampoo – a deep cleansing wash to remove embedded gunk and buildup from your hair. It is a product you don’t need regularly but need to keep in your product pile for occasional use.

A chelator accomplishes heavier lifting than your regular shampoo or clarifying shampoo. It helps eliminate mineral deposits, such as calcium and magnesium, from hard water accumulating in your hair.

Mineral buildup over time causes the hair to become dry, brittle, and difficult to manage.

A chelating shampoo has active molecules called chelating agents that do the bulk of the work.

These agents latch on to “impurities” and remove them from the hair. In other words, they form a cage around the “gunk,” so the shampoo can rinse the entire complex from your hair.1,2

Chelating Shampoo Infographic

Hair-chelating products are often packed with powerful antioxidants, removing mucky minerals and fighting free radicals from attacking your hair.

It can also benefit people with normal water, as it can help remove any product buildup or residues that may have been left on the hair.

A chelating shampoo can help to remove:

  • Gunk
  • Slime
  • Product residue
  • Hard water minerals
  • Minerals from well water
  • Chemical treatments
  • Copper residues from water pipes
  • Skin shedding
  • Color depositing shampoos
  • Oral medications
  • Chlorine
  • Salt buildup (i.e., the sea or ocean)

What Makes Chelating Shampoos Effective? (EDTA Ingredients)

EDTA is the abbreviation for Ethylamine Diamine Tetraacetic Acid. It is a colorless, water-soluble solid that dissolves limescale and ions and is a type of man-made synthetic amino acid.3,4

EDTA is a requirement in the ingredient list for a shampoo to be considered a chelator.5 Chelating shampoos can come in both drugstore and salon products.

The higher the percentage of EDTA in the product, the stronger the removal of minerals and impurities.

Note: There is a lot of confusion about chelating and EDTA-containing products. Not all products containing EDTA make it a chelator.

Some shampoos use EDTA at a very low level as a preservative. Always look for shampoos that are specifically designed as a chelating shampoo.

Ingredients with EDTA:

  • Tetrasodium EDTA
  • Disodium EDTA
  • HEDTA
  • Sodium Citrate or Trisodium Citrate
  • Tetrahydroxypropyl Ethylenediamine
  • Diisopropyl oxalate
  • Disodium EDTA-copper
  • Oxalic acid
  • Potassium
  • Sodium oxalate
  • Pentasoidum Pentetate
  • TEA-EDTA
  • Trisodium EDTA
  • Trisodium HEDTA
  • Sodium Gluconate (this ingredient can also act as a moisturizer/humectant or pH regulator)

Other chelators, such as pentasoidum pentetate, sodium gluconate, and sodium phytate, can be as effective as EDTA.

Natural Chelators

When citric acid is used in a shampoo, it adjusts pH and may not impact minerals in your hair. But it is less gentle on your hair because it is acidic.

Ingredients for Natural Chelators:

  • Phytic acid
  • Sodium gluconate
  • Citric acid (this ingredient is sometimes included in formulations to serve as a buffer, assisting in the lowering of pH levels.
  • Sodium phytate

Benefits of a Chelating Shampoo

Hair chelators remove several unwanted components from the hair and scalp. And since haircare experts often recommend them for deep cleaning, especially for curlies, you would likely conclude that they are highly beneficial.

But learning what makes them so beneficial and why deep cleansing is vital for your curly hair can help you better understand why you should incorporate them into your routine.

Here are some benefits of using a chelating shampoo:

  • Restores healthy hair.
  • Removes minerals from hard water.
  • Prevents future build-up of minerals.
  • De-yellows, gray hair.
  • Great to use before a color or chemical treatment or better results.
  • Helps to protect hair from future damage caused by hard water.
  • Neutralizes your hair and scalp to restore its natural pH balance.
  • Help to remove chlorine, salt water, and hard water minerals from the hair.
  • Help to repair damage caused by these elements.
  • Cleanses your scalp.
  • Balances the pH in your scalp and hair.
  • Works for well water.
  • Keeps your hair color vibrant and bright.
  • Lessens the effects of chlorine and saltwater exposure on hair.
  • Great for all hair types, including color-treated or chemically straightened.

How to Use a Chelating Shampoo

Now that you know exactly what chelating shampoo is and why it is such an excellent product to have and use, understanding how to use it correctly is also helpful to reap the best results and prevent further damage.

Follow these steps when using a hair chelator:

  1. Wet your hair and apply the chelating shampoo, massaging it into your scalp and hair.
  2. Leave the shampoo on for about three minutes before rinsing it out.
  3. Repeat this process until you see improvement.
  4. Use chelating shampoo approximately once a month (or as needed) to keep the minerals at bay.

When Should You Use a Chelating Shampoo?

While you can use a chelating shampoo once a month or as needed to remove build-up in your hair and scalp, there are also specific reasons you should definitely incorporate it into your routine.

Use a chelating shampoo if you have any of the following issues:

  • Chronic dryness
  • Itchy scalp
  • Limp hair
  • Frizzy hair
  • Excessive shedding or breakage 
  • Unexplained hair breakage that does not respond to your regular protein or moisturizing treatments.
  • You live in an area with hard water.
  • Your hair noticeably changes when you travel between cities or state lines (i.e., your hair is super dry because of hard water in one place, but once you travel to another location with soft water, it looks completely different).
  • You’ve recently switched to a well water source.
  • You swim a lot in chlorinated pools or saltwater.
  • You use a no-lye relaxer formula.

How Often Can You Use a Chelating Shampoo?

Chelating shampoos are not meant for everyday use and should only be used when needed. To avoid drying out your hair and stripping its natural oils, you should limit chelating shampoos to no more than one to two times per month. Use your daily shampoo for regular washes.

How to Know if Your Hair Has Hard Water Build-Up

One of the essential reasons you should invest in a chelating shampoo is because of the hard water buildup on your scalp and hair.

But how do you know if your hair is affected by the hard water and if a chelator is necessary?

Signs of hard water build up

Here are signs you have hard water buildup:

  • Your hair is dry.
  • You have an itchy scalp.
  • Your hair is limp.
  • You can’t see to get your frizz under control.
  • Your hair is breaking easily.
  • Your shampoo doesn’t lather. (Surfactants in the lather remove dirt and grime from your hair and scalp. Nothing or very little is removed without it, and you’re left with double the build-up – product residue and shampoo).
  • Your conditioners are not moisturizing your hair effectively.

Did you know that minerals can raise the pH level of tap water to around 8.5?

“Alkaline pH may increase the negative electrical charge of the hair fiber surface and, therefore, increase friction between the fibers. This may lead to cuticle damage and fiber breakage. It is a reality and not a myth that lower pH of shampoos may cause less frizzing for generating less negative static electricity on the fiber surface.6

The Difference Between Chelating and Clarifying Shampoo

Chelating shampoos are much more potent than clarifiers because they work below the surface of the hair shaft. Clarifying shampoos are meant to remove buildup on the surface of the hair.

Chelating shampoos also remove chlorine and salt buildup from the hair. If you spend a lot of time swimming, chelating shampoo is the best way to get your hair back to feeling like you just stepped out of the salon.

Both shampoos are relatively strong and can compromise your hair with repeated use. After chelating and clarifying your hair, you should follow up with a conditioner or deep conditioning treatment.

If you find these shampoos drying and continue to have chronic issues with hard water, purchase a water softener or water-filtration system, which may benefit your hair in the long run. You can always get a shower filter head to help with hard water issues.

FAQs

Are chelating shampoos good for hair?

Yes, they are good for your hair; however, chelating shampoos are not meant for everyday use and should only be used when needed.

Are chelating shampoos clarifying?

Chelating shampoos specifically target metal deposits (i.e. calcium & magnesium). The word chelation is about capturing these metal ions. Whereas clarifying is a broader term. It involves removing or getting rid of deposits. It could be metals, polymers, proteins, etc.

Can chelating shampoo damage my hair?

Not if you are using it as directed. Chelating shampoos are very strong and should only be used when your hair needs extra cleaning power. Using it more often can cause damage.

Can I use a chelating shampoo every time I wash my hair?

No, you should only use a chelating shampoo once or twice a month.

Can I use chelating shampoos on color-treated hair?

Yes, you can safely use chelating shampoo on color-treated hair. Read and follow the directions on your shampoo label to ensure you use it correctly.

Will chelating shampoos strip my hair of its natural oils?

Chelating shampoos will not strip your hair of its natural oils unless you overuse them. They primarily help remove any unwanted buildup, making your hair look and feel healthier.

Can I use a chelating shampoo on extensions?

You can use a chelating shampoo on natural hair and extensions. Follow the directions carefully to ensure the best results and prevent damage.

Is apple cider vinegar a chelating agent?

Vinegar may chelate minerals somewhat differently than citric acid or EDTA. It does not work as intensively as chelating shampoos.

Does chelating hair remove toner?

Chelating shampoos will not remove toner from your hair. They are designed to remove minerals, other unwanted buildup of pollutants, and even build-up from hair products.

How long does it take to chelate hair?

It varies depending on the chelating shampoo. However, you should not expect immediate results. Most products recommend leaving them in for at least three to five minutes.
