Does Salt Water Make Your Hair Curlier?

Salt water has been a popular hair care solution for beachgoers and hairstylists alike. While many swear by the ocean’s ability to produce those dreamy, tousled waves, others are skeptical of the science behind it. So, does salt water truly make your hair curlier? I will help you know in details below!

First, Your Hair Structure

Each strand of our hair is composed of a protein called keratin, arranged in overlapping scales called the cuticle. These keratin molecules have amino acid chains which are sensitive to environmental factors, including humidity and salinity. When exposed to these factors, the chains can break, reshape, and reform, affecting the hair’s texture and curliness.

There’s a broad spectrum of natural hair types, ranging from straight to curly to coily. Each type responds differently to environmental factors. For some, salt water might enhance the curls, while for others, it could simply add volume or texture. Understanding one’s natural hair type is essential to predict the response to salt water.

Salt Water and Curls

The Science Behind Salt Water and Curls

Salt water, also known as saline water, is water that contains a significant amount of dissolved salts (predominantly sodium chloride).

When hair is exposed to salt water, the higher concentration of salt outside the hair strand attracts the moisture from inside the hair strand. This process is called osmosis. As the hair loses its internal moisture, it contracts and becomes more textured or wavier, leading to the perception of increased curliness.

Salt water can also affect the hydrogen bonds that shape hair. When hair gets wet, these bonds are temporarily broken, allowing for potential reshaping. As salt water dries on the hair, it may aid in the reforming of these bonds in a way that accentuates the hair’s natural curl or wave.

So, Does Salt Water Make Your Hair Curlier?

No, salt water does not inherently make your hair curlier. What it does, however, is enhance and define existing natural curls and waves. The salt content in ocean water dries out the hair and removes excess oils. This drying process helps in defining the curls and waves already present in your hair, making them more visible and pronounced.

When hair is exposed to salt water, the salt ions have an interaction with the hair cuticle. This interaction can lead to the formation of microscopic fibers between cells, adding a textural element that can make waves and curls stand out even more.

Salt water can be beneficial for curly hair by providing hold and structure. This makes the curls stand out without giving the appearance of heavy product use or a “crunchy” texture.

Benefits of Sea Salt Water for Curly Hair

1. Nutrient Enrichment

Sea salt water is a natural reservoir of essential minerals like calcium, magnesium, potassium, and zinc. When incorporated into hair care, these minerals are readily absorbed, giving curly strands a boost of strength and a glistening shine.

2. Making Hair Look Thicker

Sea salt can help in increasing the volume of your hair. When applied, the salt opens up hair cuticles, making them slightly rougher. This process can give your hair more body and volume, creating the illusion of thicker hair. For individuals with thin or fine curly hair, a sea salt spray can add that desired bounce and fullness.

3. Adding More Texture to Wavy and Curly Hair

One of the most sought-after effects of sea salt is the enhanced texture it can impart. Curly and wavy hair types can particularly benefit from this. The salt encourages the natural curl pattern to tighten, emphasizing the natural waves and curls. This leads to the popular “beachy waves” look many desire, even without a trip to the shore.

4. Lightly Holding that Texture

Sea salt doesn’t just enhance hair’s texture; it can help maintain it too. While not as strong as conventional hair sprays or gels, sea salt provides a light hold that can keep curls defined and in place. It’s a more natural way to preserve the shape of curls without making them feel too heavy or sticky.

4. Treating Oily Scalp

An oily scalp can often weigh down curly hair, making it look flat and less voluminous. Sea salt can be beneficial in absorbing excess oil and balancing the scalp’s oil production over time. The antimicrobial properties of sea salt can also help in combating any scalp infections that might be contributing to excessive oiliness.

5. Combatting Fungal Dandruff

Dandruff, particularly of the fungal variety, can be a nemesis for those with curly hair. Sea salt water, with its moisture-absorbing properties, makes the scalp a hostile environment for fungi. By reducing fungal dandruff, the scalp remains healthy, preventing itches and ensuring curls remain flawless

Is Sea Salt Spray Good for Your Hair?

Sea salt spray has become a staple in many hair care routines, mainly for its ability to create effortless, beachy waves. The spray can enhance the natural texture of the hair, making waves and curls more pronounced. For those with straight hair, it can introduce a wavy texture, giving the hair a fresh, tousled appearance.

Beyond aesthetics, sea salt spray can absorb excess oil from the scalp and hair, making it a great pick-me-up for hair that’s beginning to look greasy. The minerals present in sea salt, like magnesium, calcium, and potassium, can also offer some nourishment to the hair, potentially strengthening the hair shaft.

While sea salt spray offers various benefits, it’s essential to be aware of its potential downsides. The primary concern is that it can be drying. Since salt is hygroscopic, meaning it draws out moisture, prolonged and frequent use can lead to dehydrated hair, making it brittle and prone to breakage.

Additionally, for those with color-treated hair, sea salt spray might accelerate color fading. The salt can open up the hair cuticle, allowing the color to wash out more easily. It can also cause colored hair to appear duller over time due to the roughening of the hair’s surface.

DIY Sea Salt Spray

Creating your own sea salt spray at home is not only cost-effective but also allows you to customize the blend according to your hair and skin needs. Here’s a simple recipe and guidelines to craft your personalized sea salt spray:

Basic Ingredients

  • Distilled Water: Acts as the base for your spray. You can start with about one cup.
  • Sea Salt: This is the main ingredient that provides the texture. Typically, 1-2 tablespoons are used, but you can adjust depending on your desired texture level.
  • Hair Oil or Conditioner: To counteract the potential drying effect of the salt. Coconut oil, argan oil, or even a few drops of your favorite hair conditioner can work. Typically, a teaspoon is enough.
  • Optional Add-ins: For fragrance or additional benefits. You can consider essential oils like lavender or rosemary for scent and added hair nourishment.

Step-by-Step Preparation

  1. Heat the Water: In a pot, gently heat the distilled water but don’t bring it to a boil. Warm water helps dissolve the salt more efficiently.
  2. Dissolve the Sea Salt: Once the water is warm, remove it from heat and add your sea salt. Stir until the salt is completely dissolved.
  3. Add the Hair Oil or Conditioner: While the water is still warm, add your chosen oil or conditioner. Stir until it’s thoroughly mixed in. This ingredient helps to moisturize the hair and counteract the drying effect of the salt.
  4. Incorporate Essential Oils: If you’re using essential oils for fragrance or additional benefits, add a few drops now. Stir well.
  5. Transfer and Store: Once the mixture has cooled to room temperature, use a funnel to pour it into a spray bottle. Ensure the bottle is clean and dry. Store your DIY sea salt spray at room temperature, and aim to use it within a month for the best results.

The blend was easy to make, and the ingredients were straightforward to source. I loved the added touch of essential oils, which gave my hair a pleasant scent. After using it, my hair had that desirable beachy texture without feeling too dry, thanks to the added oil. It’s a cost-effective alternative to store-bought versions.

How to Use Sea Salt Spray Efficiently?

Step 1: Choose the Right Product

Not all sea salt sprays are created equal. Depending on your hair type and desired outcome, you may want to choose a product with additional moisturizing ingredients or one specifically designed for color-treated hair. Checking product reviews or seeking recommendations can help you make an informed choice.

Step 2: Start with Damp Hair

While you can apply sea salt spray to dry hair for a quick texture boost, starting with damp hair allows for more even distribution and a more pronounced beachy effect. After washing your hair, towel dry it gently to remove excess water.

Divide your hair into sections to ensure that the product is applied evenly. Depending on your hair’s thickness and length, 2 to 4 sections might be sufficient.

Step 3: Apply the Spray

Hold the sea salt spray about 6-8 inches away from your hair and spritz it onto each section. Focus primarily on the lengths and ends rather than the roots to prevent the scalp from drying out or looking too greasy.

After applying, scrunch your hair with your hands to enhance natural waves and curls. If you desire a more tousled look, you can twist individual sections after spraying.

Step 4: Dry Naturally or Diffuse

For a more natural, relaxed wave, allow your hair to air dry. If you’re in a rush or want more volume and definition, use a hairdryer with a diffuser attachment on a low heat setting. The diffuser will enhance the wave without causing frizz.

If you feel that your hair is a bit dry after using the sea salt spray, consider applying a light hair oil or leave-in conditioner to the ends. This will counteract the drying effects of the salt and leave your hair feeling soft and manageable.

Optimal Frequency for Using Sea Salt Spray

For creating beach-like waves and volume, use sea salt spray 1-2 times a week on damp hair, avoiding the roots to prevent greasiness. For styling short hair, apply on dry hair as needed for texture or on damp hair before blow-drying for volume. For enhancing straight, flat hair, use 2-3 times a week on damp or dry hair and before styling to prolong the look. If using for skin benefits, apply every 2 days for sensitive skin or up to twice daily for normal to oily skin, followed by moisturizing.


The allure of beachy waves and the association of salt water with those relaxed, vacation-inspired curls have been long-standing. Indeed, salt water can enhance the natural patterns of our hair, giving it that sought-after wavy or curly appearance. While it does provide a texturized effect and can indeed accentuate curls, it’s essential to understand its overall impact on hair health and use it judiciously.
