The Truth about Salt Free Shampoos

In addition to cleansing and conditioning agents, shampoo formulas often contain active ingredients for treating various scalp and hair conditions as well as additives to make the product more visually appealing or to increase its shelf life.

Thickeners are additives used to increase viscosity, which makes the product less runny and therefore easier to spread across the hair.

Sodium chloride, the chemical name for common table salt, is the most widely used viscosity enhancer in shampoo formulas. It is commonly used in combination with sulfate surfactants to enhance viscosity, giving the shampoo a creamy texture.

Manufacturers prefer using sodium chloride for thickening purposes because it is an effective and fairly cheap thickening agent.

Our list of suggested salt-free products is at the end of this post.

Is Sodium Chloride Safe for Topical Applications?

The Environmental Working Group (EWG) rated sodium chloride as a low hazard. Some animal studies show it to be a skin irritant at medium doses, and the safety data sheet shows that sodium chloride may slightly irritate skin and eyes.

That means that sodium chloride is considered relatively safe when used in personal care products, and you can often find it listed on the ingredient label of shampoos at all price and quality points.

Is Salt Bad for Your Hair?

Sodium chloride is a highly hygroscopic substance, meaning it tends to attract water from its surroundings. Consequently, salt can encourage dryness by absorbing moisture from your hair. Just as consuming foods high in sodium chloride increases thirst, salt can leave your hair feeling dry.

For people with dry and naturally curly hair, it is advisable to use salt-free hair products, especially if they are meant to be left on the hair. People with oily and normal hair can be more comfortable with salt-containing products, especially when it comes to hair shampoos.

However, the amount of salt in a shampoo formula won’t have a significant drying effect on your hair, especially when the shampoo is applied for a short time. The salt will be washed away with the shampoo and will not remain in your hair.

Does It Have Any Benefits?

Manufacturers use sodium chloride because it is cheap and efficient. Because it is an organic ingredient, sodium chloride is widely used in organic shampoo formulas.

People with an oily scalp and hair can benefit from using a sea salt scrub mask. Sea salt is preferable to plain salt for scalp nourishing purposes because it contains naturally-occurring trace minerals, while table salt has been chemically treated to remove trace elements such as calcium, magnesium, potassium, bromine, zinc, and sulfur. However, table salt contains a small amount of added iodine, which is known for its ability to increase follicle strength and restore hair growth when applied topically.

Why Use a Salt-Free Shampoo?

If you have invested in a Keratin treatment, you probably already know that using harsh shampoos and other inappropriate hair care products can strip the treatment of your hair, and salt is one of the ingredients to avoid.

Therefore, to make sure that your shampoo will not undo the results of your keratin treatment, you should only use gentle hair shampoos that are made without sodium chloride and harsh sulfate cleaners.

Shampoos without salt have become a trend because of the increased popularity of keratin straightening and smoothing treatments, so manufacturers with salt-free shampoos will advertise this fact, so you can easily find them online and at many local beauty stores. Below are several sodium chloride free shampoos, which are also free of harsh sulfate cleansers and made preferably with natural ingredients:
