Is salt water good for your hair?

You might opt to visit the beach as summer draws near and the days get warmer, but even while taking a swim in the ocean might be soothing, you might be concerned about what would happen to your hair if you dipped it in seawater.

Although there is a lack of scientific evidence regarding the effects of saltwater on hair, it is evident that saltwater does have an effect because some hair products on the market contain saltwater directly. However, these products are designed to style hair, not to address the question of whether or not saltwater is good for hair.

Sunlight and saltwater go hand in hand, and this is when hair damage is most likely to occur; the sun’s strong UV rays, the drying effect of the saltwater, and the hot, dry air can all harm hair. In addition to discussing the potential benefits of salt water for hair, this article will also address the potential harm it can do to hair and how to shield your locks from its damaging effects.

Scientific proof supporting the benefits of saltwater for hair health or its potential to harm hair is lacking. The results of saltwater on hair might vary depending on how it is used or interacts with the hair, as you will see throughout this article. Saltwater can have both beneficial and negative impacts on hair.

In terms of advantages for hair, saltwater can provide body and structure, particularly for people who want “beachy waves.” However, in terms of drawbacks, saltwater can deplete hair of its natural oils, make it brittle, and even break it. It’s critical to limit the amount of saltwater that comes into contact with hair when swimming in the ocean or using any form of saltwater, and to wash and moisturize the hair afterward.

The Study of Saltwater Science

Is salt water good for your hair? The main ingredient in saltwater is sodium chloride, or salt, dissolved in water. Because of its special qualities, it can have a favourable or negative effect on our hair when it comes into contact with it. Although there isn’t much scientific proof to back up the reputation of saltwater’s ability to cleanse skin, it nonetheless possesses this quality. It does, however, include antimicrobial elements including zinc, magnesium, potassium, selenium, and amino acids. 

Because deep ocean water is found at depths of 200 metres or more, its mineral-balancing and toxin-reducing properties may help with skin diseases like eczema. This water has been associated with treating skin conditions such as cracking, irritation, dryness, itching, and swelling because it is less exposed to sunlight and has fewer microorganisms. It also holds more nutrients.

As an exfoliator, saltwater can get rid of extra oil, debris, and dead skin cells. Numerous physicians believe that the abundance of minerals in seawater helps with a variety of skin issues. Saltwater can, however, lessen the appearance of scars and acne while also encouraging skin cell renewal, so people with sensitive skin should use caution.

Now let’s talk about salt water for hair. Because of its hygroscopic properties, saltwater can form salt crystals that absorb moisture from hair strands, making hair brittle and dry, especially for hair that has been chemically treated or dyed. Before swimming in salt water, oiling your hair can help prevent damage and colour fading.

How about seawater?

When someone refers to “salt water,” they could be referring to saltwater or salt-containing water. Seawater contains additional minerals, but salt water is just water with salt in it. This is the main distinction between the two.

The two most common minerals in saltwater are sodium and chlorine, as you can see below.

Although you may be thinking of the overpowering chlorine found in swimming pools, seawater contains a distinct kind of chlorine. Whereas the chlorine in swimming pools is dissolved chlorine gas (Cl2), an aggressive chemical that isn’t found in nature, the chlorine in saltwater is in the form of a chloride ion (Cl-), a component of table salt and a harmless element. 

Ocean water’s mineral composition:

  • Chlorine: 55%
  •  Sodium: 31% 
  •  Magnesium: 7.7%
  • Sulphur: 3.7% 
  • Calcium: 1.2%
  • Extra: 1.4% 

Although there isn’t any scientific proof to back up the claim that these minerals hurt hair, it’s crucial to remember that chlorine (Cl2) would only cause problems if you regularly used a swimming pool without washing your hair afterwards. 

Regarding the impact of seawater’s salt content, if hair is left unwashed, salt crystals may accumulate in it and cause damage like brittleness.

How is hair harmed by saltwater?

Because seawater contains a high concentration of minerals and vitamins, it can be used for wound healing, skin detoxification, and reducing edoema. It’s crucial to recognise that it might have negative impacts on your hair.

Let’s first accept that moderate exposure is harmless. If you use seawater wisely, it can even be advantageous. However, summertime heat waves and persistent salinity can lead to hair loss or other kinds of damage to the hair.

Wicking away moisture

Because of its high water content, your hair is supple, elastic, and moisturising just like your skin. In that sense, excessive moisture loss can cause hair to become dehydrated.

Seawater’s strong salinity can suck moisture from your hair and scalp. Because saltwater has a purifying impact, it may also help reduce the natural oils in your scalp.

After visiting the beach, you might observe that blow-drying your hair will take longer, or that curling or keeping a style will be difficult. Hair gets dry, brittle, and more delicate after losing moisture and its natural oils.

Frizzing and twisted strands

Furthermore, saline water may disrupt several bonding interactions and produce new cross-links within hair strands. Therefore, in addition to providing your hair with gorgeous beach waves, salt water can weaken it and remove its luster and smoothness.


In addition to dandruff, saltwater damage can cause hair breakage and splitting at the ends in their most severe form. When hair is processed or dyed, these impacts are significantly more severe. Saltwater damage not only gives colored hair a coarse texture but also changes the color of the hair. Thus, keep in mind to give your dyed hair extra attention.

In the absence of appropriate care, your hair may become lifeless, tangled, and coarse to the touch throughout the summer months.

Why does salt water harm things so much?

Water-swollen hair shafts

Since hair may absorb water, excessive swimming may increase the amount of water that enters the hair. The condition of the hair shaft may suffer from continuous wetting if the cuticle is already damaged or excessively porous.

Your hair shafts expand with water while submerged in the sea because the cuticle’s protective function has already been compromised. The recurrent expansion and contraction cause the hair to progressively deteriorate. Additionally, the friction between the water and hair cuticles when swimming may harm them.

The process of osmosis

Osmosis is the act of transferring water between two locations to balance the concentrations of solutes by passing it through a semipermeable membrane, a form of barrier that allows certain particles to pass through while blocking others.

The concentration of salt in the water inside your hair and the surrounding saltwater varies when your hair is submerged in seawater. Water therefore undergoes a reaction when it travels from your hair, which has a lower salt concentration, to seawater, which has a higher salt concentration.

This process causes the inside of your hair strand to become dry and brittle by removing moisture.

Additionally, Tape In Hair Extensions  that is deficient in moisture is more likely to frizz or fly away.

Salt crystals and hydrogen bonds are growing.

The keratin protein gets dehydrated when swimming on the beach. A dry environment like this allows saltwater molecules to penetrate the hair fiber, dissolving the preexisting hydrogen bonds in the hair and creating new ones. As a result, blow-drying your hair will take longer, and any styling you do after going to the beach will be considerably harder.  Seawater’s salt may deposit hard crystals on your hair after swimming, further causing mechanical abrasion to the cuticle. These crystals cause your hair to have a less pleasant texture and a coarser surface. When nearby hairs are more likely to tangle, tangling also gets worse.

Advantages of seawater for hair

Shampoo with antifungal properties

Seawater works well as a natural shampoo. You can avoid having greasy hair by occasionally washing your hair with salty water to assist you get rid of extra heavy oils. Fresh, clean hair and scalp are the result. It’s also been shown to give your hair more volume and get rid of dandruff.

Swimming in the sea gives your scalp a free, all-natural exfoliation. Seawater crystals rich in minerals can be a great way to exfoliate your scalp by eliminating product build-up from the roots of your hair and increasing blood flow.

Minerals and nutrients found naturally

The nutrients that your body needs are abundant in saltwater. For instance, magnesium has been shown to support both muscular relaxation and nervous system strength. The relaxing properties of magnesium are advantageous and have been connected to faster hair growth.

How can you prevent saltwater damage to your hair?

It is a good idea to use these strategies to shield your hair from the harmful effects that salt water can have.

  • Wet your hair before going in the sea; this will prevent seawater from penetrating the strands as much as if you let your hair absorb fresh water first.
  • After soaking your hair in saltwater, rinse it off to make sure no salt crystals are left behind and to stop the salt water from evaporating into your hair strands.
  • Use a moisturising shampoo and conditioner to add moisture to your hair. Another option is to use a leave-in conditioner.
  • Think about donning a swim cap—this is an excellent method to shield your hair from saltwater or prevent overexposure.
  • When using salt water spray, especially for styling purposes, use discretion. If at all feasible, follow up with moisturising treatments.

Extra sun advice

Apply a sun protection hair cream with SPF to your hair to help shield your scalp from UV rays. Using a Q-tip dipped in broad-spectrum sunscreen and applying it straight to the section line is another easy yet effective technique.
