Any pool chemicals or ocean salt poses a threat to your hair health, whether or not you suffer from a hair loss condition. These agents tend to make hair feel dry and brittle, which is easily remedied by reducing your swim sessions and practicing routine deep conditioning hair masks
The water of the swimming pool essentially contains chlorine, which work as an effective anti-bacterial and anti-algae agent, helping the pool water to stay clean and hygienic. The problem is that, no matter how good it is for keeping the pool water hygienic, chlorine takes a negative toll on your hairs. It damages the cuticles of the hair shafts, which triggers hair fall through breakage and in addition to that chlorine can also harm the hair follicles on the scalp which can cause extreme hair loss.
Being a natural product, ocean salt (sea water) should be less damaging to hair than chlorine
Either way, in this article you will find some useful tips on caring for your hair to minimise the damage.
