Is Sea Water Harmful to Bleached Hair? What You Need to Know

Is your dream beach vacation harming your beautiful bleached hair? While you enjoy the sun and surf, sea water might be more than just refreshing—it could be damaging your hair. But is this really true for bleached hair? 

In this article, we’ll find out if ocean dips are a threat to your gorgeous locks and share tips to keep your hair safe. 

Let’s dive in and discover the truth about sea water and bleached hair!

What is Hair Bleaching?

Hair bleaching is a fun way to lighten your hair by removing its natural pigments. This process usually involves using bleach (often hydrogen peroxide) along with an alkaline agent. Together, they open up the hair cuticle and dissolve the melanin, giving you beautiful, lighter hair that can range from a subtle shade change to a striking platinum blonde!

How It Works

  1. Alkaline Agent: This raises the pH of your hair, opening the cuticle, which is the protective outer layer.
  2. Hydrogen Peroxide: Once the cuticle is open, hydrogen peroxide gets to work inside the hair, breaking down the melanin and lightening your hair.

Effects on Your Hair

Bleaching can change your hair’s structure and health:

  1. Cuticle Damage: Opening the cuticle can make it rough and dry, leaving your hair more vulnerable to damage.
  2. Moisture Loss: Bleaching strips away natural oils, leading to dryness and brittleness, which can cause frizz and breakage.
  3. Increased Porosity: Bleached hair becomes more porous, making it easier to absorb and lose moisture, which can affect color retention.
  4. Weakened Structure: The process can weaken hair, making it more prone to split ends and breakage.

Knowing how to care for bleached hair is key to keeping it healthy and vibrant, especially when you’re enjoying activities like swimming in the ocean!

Composition of Seawater

To understand how sea water affects bleached hair, it’s important to know what’s in it:

  • Salt: The main ingredient in sea water, salt can dry out your hair.
  • Magnesium: This mineral can make hair feel rough and hard to manage.
  • Calcium: It can build up on hair, making it look dull and preventing moisture from getting in.
  • Potassium: Good in small amounts, but too much can also dry out hair.
  • Sulfate: This can dry out both hair and scalp, which is bad for sensitive or damaged hair.
  • Other Minerals: Sea water has various minerals that can build up in your hair and are tough to rinse out.

Together, these elements can be tough on bleached hair, stripping moisture and causing buildup. Knowing this can help you create better hair care routines before and after going in the sea.

Is Sea Water Harmful to Bleached Hair?

Yes, sea water can harm bleached hair. The high salt and minerals can dry it out and make it brittle, which increases the risk of breakage. Since bleached hair is already weak and porous, it’s even more sensitive to the drying effects of sea water.

FAQs

Will salt water turn my bleached hair green?

Yes, salt water can turn bleached hair green, especially if it’s been treated or exposed to chlorine. The minerals in salt water may react with the chemicals in the bleach, leading to a greenish tint.

Does sun ruin bleached hair?

Yes, the sun can damage bleached hair by causing it to become dry, brittle, and fade in color. UV rays can break down the hair’s protein structure and strip moisture, so it’s important to use UV protection products and limit sun exposure to keep bleached hair healthy.

How to protect bleached hair on vacation?

To protect bleached hair on vacation, use a hydrating leave-in conditioner, wear a hat in the sun, rinse with fresh water after swimming, and avoid excessive heat styling.
