Is salt water good for your hair

Although salt water is good for hair, on the other side it can also be damaging when your hair gets overexposed to the seawater. You might have noticed that if you have dipped your hair in the ocean and fully submerged it, the hair will probably not be easy to comb out later on that day. 

The elasticity, hydration, and moisture of the hair are locked by the water content that is in the hair, but when you get exposed to salt water at an extreme level, the strands can become dehydrated and gets parched if too much moisture is lost. If you sit in the seawater for a longer period of time, the salt water will draw the moisture, leaving the hair dull, hard to manage, and with hair tangles. Here are a few ​​effects of salt water on hair. 

Dries out the hair 

After swimming in the seawater, you would have noticed the skin becoming dry, and the hair gets fizzy and dehydrated. The seawater has a high salt concentration and those salt crystals will wick away the moisture from the hair leaving it dehydrated and fragile. 

 If your hair is chemically treated like dying or bleaching, it can become extremely dried by seawater. Because the chemical treatment would have already stripped your hair from the nutrients and would have artificially changed the cross-links within the hair strands. The saltwater that contains hygroscopic properties would take away the moisture even from the healthy hair and it would further worsen the strands that are chemically altered. 

When overexposed, it fades or changes the hair color and makes it rough causing it split ends and breakage. So if your hair is chemically treated, you need to give more attention and care while spending time by the sea to remain healthy and hydrated. 

Hair shafts swelling with water

The hair is permeable to water and if you swim too much in the seawater, it can enhance the water penetration to the hair. If the hair cuticle is damaged, there can be negative impacts when you wet the hair repeatedly with seawater. When the hair gets immersed in the sea, the hair shaft swells with water, given that the protecting effect of the cuticle is already inhibited. When you expose the hair repeatedly to seawater, it gradually weakens the hair. 

Lack moistures 

There is a difference in the salt concentrations between the water in the hair and the salt water surrounding it. So when you submerge in seawater, a reaction happens where the water moves from an area of lower salt concentration which is in your hair to an area of high salt concentration which is the seawater. This removes the moisture from the interior of your hair strand and leaves it brittle. The hair will get more prone to frizziness and flyaways when it lacks moisture. 

The keratin protein will become dehydrated when you swim on the beach. This will enable the molecules in salt water to enter the hair fiber and breaks the hair preset hydrogen bonds and form new ones. So you will need more time to blow0dry the hair and when you try to do styling works for the hair, it will be more difficult. 

The salt in seawater will leave the hard crystals on the hair and further develops mechanical abrasion to the cuticle.  You will notice a rough hair surface and an unpleasant hair texture. The tangling of hair increases when adjacent hairs are more prone to get caught together.

What are the alternatives for ocean water?

For those who do not live near the ocean, there is a remedy that gives the effects of dipping into the ocean. You can mix two parts of castile soap and three parts of sea salt in a bowl and blend thoroughly. Wash the hair with the mixture for 15 minutes and then rinse with cold water to eliminate the residue. 

Or you can mix three tablespoons of sea salt with warm water and massage the scalp for 6 to 8 minutes. You can rinse thoroughly with cold water afterward. You can also create a saltwater treatment by mixing 1 tbsp of warm water and 1 tbsp of sea salt into a spray bottle until the salt dissolves.  Next, add 1 tbsp coconut oil and 1 tbsp leave-in conditioner. Do not wash your hair with these solutions more than once a month to avoid developing follicle damage and rough hair.
