After swimming, especially in chlorinated water, your hair typically becomes dry and dull due to the stripping away of its natural protective oils. Chlorine, while effective at killing bacteria, unfortunately also removes sebum, the natural oil that keeps your hair moisturized and healthy.
Here's a more detailed breakdown:
-
Chlorine's Impact: Chlorine acts as a powerful oxidizing agent. This means it reacts with and damages the hair's protein structure (keratin).
-
Sebum Removal: Chlorine strips away the sebum, which naturally moisturizes and protects the hair shaft. This leads to dryness and brittleness.
-
Potential for Discoloration: In certain cases, chlorine can react with metals (like copper) present in the water or your hair products, leading to discoloration, particularly for blonde or light-colored hair (often a greenish tint).
-
Increased Porosity: Repeated exposure to chlorine can increase the hair's porosity, making it more susceptible to damage and breakage. This means the hair shaft has more gaps and holes, allowing it to absorb more water (and chlorine) but struggle to retain moisture.
How to Protect Your Hair While Swimming:
-
Wet Your Hair First: Before entering the pool, thoroughly wet your hair with clean, non-chlorinated water. This helps to saturate the hair shaft, reducing the amount of chlorinated water it can absorb.
-
Apply a Leave-In Conditioner or Hair Oil: Coat your hair with a leave-in conditioner or a natural oil (like coconut or olive oil) to create a barrier against the chlorine.
-
Wear a Swim Cap: A swim cap is the most effective way to protect your hair from direct contact with chlorinated water. Ensure the cap fits snugly to minimize water seepage.
-
Rinse Immediately After Swimming: As soon as you get out of the pool, rinse your hair thoroughly with clean water to remove any residual chlorine.
-
Use a Clarifying Shampoo: Once a week, use a clarifying shampoo to remove any buildup of chlorine and minerals. Follow with a moisturizing conditioner to replenish lost moisture.
-
Deep Condition Regularly: Use a deep conditioner or hair mask once or twice a week to help restore moisture and repair any damage.
-
Consider a Swim-Specific Shampoo: There are shampoos specifically formulated to remove chlorine from hair. These can be very effective at preventing damage.
By taking these preventative measures, you can minimize the negative effects of chlorine on your hair and maintain its health and shine.
