* Salt Content: Sea water contains a high concentration of salt (sodium chloride). Salt is hygroscopic, meaning it attracts and absorbs moisture. When sea water comes into contact with permed hair, the salt draws moisture out of the hair shaft, leading to dryness, frizz, and loss of definition in the perm.
* pH Levels: The pH of sea water is typically alkaline (around 8), while hair thrives in a slightly acidic environment (around 4.5-5.5). The alkaline pH of sea water can disrupt the hair's natural pH balance, causing the hair cuticle to open up. This makes the hair more porous, susceptible to damage, and prone to tangling.
* Mineral Buildup: Sea water contains various minerals like magnesium, calcium, and others. These minerals can build up on the hair shaft over time, making the hair feel stiff, dull, and difficult to manage. Mineral buildup can also interfere with the effectiveness of hair products.
* Perm Vulnerability: Perming involves chemical processes that alter the hair's structure. Immediately after a perm, the hair is more fragile and sensitive than usual. Exposure to the harsh elements in sea water can exacerbate damage to the already stressed hair.
How to Protect Recently Permed Hair from Sea Water:
* Wet Hair First: Before entering the sea, wet your hair thoroughly with fresh water. This helps to saturate the hair shaft, reducing the amount of sea water it can absorb.
* Apply a Protective Product: Coat your hair with a leave-in conditioner or hair oil that contains UV protection. This creates a barrier against the harmful effects of salt and sun.
* Wear a Swim Cap: A swim cap is the most effective way to shield your hair from direct contact with sea water.
* Rinse Immediately: As soon as you're done swimming, rinse your hair thoroughly with fresh water to remove as much salt as possible.
* Use a Gentle Shampoo and Conditioner: After rinsing, wash your hair with a mild, sulfate-free shampoo designed for permed or chemically treated hair. Follow up with a moisturizing conditioner to replenish lost moisture.
* Deep Condition Regularly: Incorporate a deep conditioning treatment into your hair care routine once or twice a week to provide extra hydration and repair.
* Avoid Heat Styling: Minimize the use of heat styling tools (blow dryers, curling irons, etc.) as they can further dry out and damage permed hair. Air-drying is preferable.
* Regular Trims: Get regular trims to remove split ends and maintain the overall health and appearance of your perm.
In summary, sea water is not kind to permed hair, especially recently permed hair. Taking precautions to protect your hair before and after swimming can minimize the damage and help maintain the health and longevity of your perm.
