Soak your hair in the shower until it is entirely saturated. This may feel like your head is heavy. Consider rinsing with cool water if you can. Warm water opens up the hair’s cuticle while cool water helps keep it closed. Using cool water may expose your hair to less chlorine. [3] X Research source
Cover all of your hair with a product such as an oil or silicone-based conditioner. Hair serums also work well. If you prefer a natural product, coconut oil is a great alternative. Recognize that protective layers of hair product or coconut oil will not leave a residue in the water.
Purchase a latex or silicone swim cap. You can get these at sports stores, large retailers, and swimming stores.
Rinse your hair for a minute or two to remove the barrier product and any chlorine. This will allow any shampoo and conditioner to better penetrate your hair. You can also try an apple cider vinegar rinse to help get the chlorine out of your hair. After shampooing and rinsing your hair with plain water, rinse it again with a mixture of one part apple cider vinegar and two parts water. Then rinse your hair with plain water again.
Use a product designed for deep conditioning. You can switch back to regular conditioner on the days you don’t swim. Consider spraying on a leave-in conditioner so that your hair gets the benefits of moisturize throughout the day.
Consider getting a shower gel or wash with vitamin C. This can help further neutralize the chlorine on your skin and get it to wash away.
Use a moisturizer that is high in antioxidants such as vitamins C and E. These are not only very high in moisture, but can further neutralize any lingering chlorine on your skin. Select a moisturizer that is a heavy cream instead of a lotion. Thicker products are generally more moisturizing than thinner ones.
