So, you want to dye your hair but have just finished swimming in the salty ocean water. It’s important to know that it won’t end well if you do it immediately.

The best way is to first get all the salt out of your hair before you can dye your hair. You should always head to the salon to get it done correctly.

A qualified stylist knows what you need to do to get rid of all the salt. This is because salt itself contains Chlorine and can serve as a bleaching agent.

Once more, the chemicals in the hair dye will react with the salt and this can cause serious effects on your hair.


Facts about Swimming With Permanent Hair Dye


Most of us have been dyeing our hair different shades for as long as we can remember. For the most part, we know what is important when it comes to maintaining our hair once it’s colored.

You have to cover your dyed hair if you are swimming in chlorinated water. Chlorine tends to lift the hair dye which is something no one wants.

Invest in a good swim cap to prevent your color from fading too fast. If your hair is dyed, and you spend a lot of time in the pool or seawater, you’ll need to wash your hair frequently.

Use a good swimmers’ shampoo and deep conditioner to restore moisture and oils to your hair. Chlorine strips it off leaving your hair dry and dull.

Saltwater can have similar effects on your dyed hair as chlorinated water. There is a high concentration of salt in the ocean.

To avoid these effects being adverse, wash your hair thoroughly (not just rinsing it) after you leave the beach.

Effects of Chlorine on Bleached Hair


Other than knowing what Chlorine does to red-dyed hair, let’s also discuss some of the effects of Chlorine on bleaches hair.

When you bleach your hair, you remove its natural color leaving it lighter than its normal shade. There are two agents involved here.

You have an alkaline agent responsible for opening up the hair cuticles getting them ready for the alteration. Then in comes an agent for oxidation that penetrates the hair and strips its natural color, leaving it lighter.

The more the bleaching agent stays on your hair the lighter it becomes. The texture of your hair is affected in the process and you may end up with less elastic hair.

Chlorine is a very reactive chemical and even though it’s beneficial to the pool, it has the opposite effect on hair. Bleached hair is lighter than its normal shade.

Lighter colors react with chlorine making the hair appear greenish. The most affected are people with bleach blonde hair.

You have to take some precautions if you intend to go swimming regularly in chlorinated water with bleached hair.

You can opt to apply a leave-in hair conditioner before heading out for a swim. This will offer it more protection against the effects of salty or chlorinated water.

Additionally, you have to wet your hair with clean cold water before jumping into the pool or heading into the ocean.

This helps your hair not to absorb too much chlorine or saltwater when it comes into contact with it.


Swimming With Highlighted Hair


When you highlight your hair, you change the natural pigment of strands using a hair lightener or color.

It can be done on all types of hair including chemically-treated hair. This means you don’t color all the hair, just some strands.

There are four different types of highlighting that people do. You can opt for permanent, semi-permanent, demi-permanent, or temporary.

For most people, this is one way to make their hair appear fuller. It’s also preferred by people with graying hair as a way of changing the gray pigment of the new growth especially when it’s singular strands.

Hair highlights are the preferred option for those who want to have a fun look but not alter the color of their hair too much.

Not everyone is an avid fan of the complete color change. Highlights remain on the strands and barely touch the base of the hair. Highlights can be more than one color or shade.

You don’t have to settle for only one. Consult a colorist who knows how to blend different colors and let them work some magic on your hair.


Facts about Swimming With Highlighted Hair


Whether at the swimming pool or in the ocean, your highlights are bound to feel the effects. Even if you love being in the pool or ocean, try not to go in with freshly done highlights.

Deep condition your hair prior to swimming to add more moisture and natural oils into it. This helps your hair to remain moisturized and healthy even with constant swimming. This is one way to swim-proof your hair.

You can also run some fresh cold water through your hair before plunging into the pool or ocean. Dry hair absorbs the chlorine or salt in the water like a sponge leaving a lot of room for this water to affect your hair.

Add oils like Argan or coconut to it after wetting it to offer more protection.

Lastly, wash your hair as soon as you’re done swimming with a color-safe shampoo to remove all traces of the chlorinated water or seawater.

Follow this up with deep conditioning for a few minutes to restore moisture and oils to it.
