Cons Of Salt Water

Sometimes, ocean water can be a bit too much for you. Even if you have healthy hair, ocean water can do damage.

So, the question is does salt water damage hair? Well, besides providing various benefits, you should not overexpose your hair to the sun and sea. Overexposure can lead to dry hair, tangled hair, and hair that loses its flexibility.

Speaking of drying your hair, after swimming in salty water, the hair gets dehydrated. It is the water that makes it moisturized and elastic. But because sea water has a high salt concentration, it will strip away moisture from your hair. Do not overexpose your hair and do not swim for a whole day.

If you have dyed hair, sea water can ruin your hair. Colored hair and bleached hair should stay away from sea water. Salty water can alter the crosslinks within your hair’s structure and worsen the condition. It can fade or change your hair color.

Why Does Sea Water Cause Damage?

Well, we have to start from the beginning. Hair is permeable to water, which means too much swimming can enhance water penetration into hair. And if your hair cuticle is already damaged, repeated wetting will cause a negative impact on the hair shaft.

When you are spending too much time in the sea, your hair shafts swell with water. That gives them a protective effect. Yet, if you continue with repeated expansion and contraction, it will gradually weaken the hair. Swimming also hurts hair cuticles by friction with the water.

The Osmosis Effect

We also have to mention the osmosis effect. It is the process of moving water across a semipermeable membrane to balance the solute concentrations between two areas. This is called osmosis.

So, when your hair submerges in sea water, there is a difference in salt concentration between the water within your hair and the water surrounding it. This will cause a reaction where water moves from an area of lower salt, which is your hair, to an area of higher salt, which is the sea.

The procedure will remove moisture from the interior of your hair strand, leaving it dry and brittle. This often results in frizzy hair.

Hair Care Precautions

Now let’s talk about some precautions about sea water. We talked mostly about is salt water good for your hair. We mentioned the pros and cons. But let’s talk about some safety measures you can make to ensure your hair is healthy after swimming.

First and foremost, it is not recommended to expose your hair to ocean water if you have recently treated your hair with chemicals. This includes hair dye and bleach. Remember, treated hair has already been stripped of its nutrients. Salt water will make things worse.

Dyed hair can fade with excessive salt water exposure.

Should You Wash Your Hair After Swimming?

This is an obvious answer, yet, we still have to do it. It is important to wash your hair following swimming in the ocean.

Prolonged exposure to sea water and ocean water can lead to irreversible damage to your hair. It is essential that you rinse it after swimming as soon as possible. This is why most top-rated beaches have showers at the beach. So that you can rinse your hair instantly after swimming.

Rinsing your hair after swimming will remove sand, but also other debris, dirt, and chemical that are stuck in the hair because of the water.

You should also use hair cream with SPF to prevent damage from exposure to UV rays.
