Before entering the pool, it is suggested to take a quick shower with clean water. Wet skin is likely to absorb less chlorinated water, thus reducing the drying effects of pool chemicals. 

Hair often soaks up the chlorinated water, which can lead to dryness, breakage, & discolouration. Wearing a swim cap will provide an extra layer of protection, especially for those who swim regularly

Once you're out of the water, make sure to rinse off as soon as possible. Use a gentle cleanser to remove chlorine, salt, and impurities from your skin. 

After showering, apply a nourishing moisturiser rich in ingredients such as hyaluronic acid, glycerin, or ceramides to retain hydration. Follow up with a conditioner or hair mask to restore moisture.

Always apply a broad-spectrum sunscreen with SPF 30 or higher at least 15–20 minutes before swimming, and reapply after extended periods in the water. Wearing a hat can also provide added protection.
